Remediation quantum of organic amendments to immobilize potentially toxic heavy metals in wastewater-contaminated soils through maize cultivation

Wastewater is considered a good reservoir of mineral elements that can be used for agriculture, aquaculture, and some other activities after adopting suitable measures. The gap between supply and demand for water is increasing exponentially because of the abrupt boost to the world’s population. This poses a threat to human life as it has reached alarming levels in some parts of the globe. Normally, wastewater consists of liquid waste produced by commercial or industrial sources for daily use, consumption, and production. It is time to refocus our attention on a kind of circulating water system by reusing municipal wastewater for agricultural purposes, particularly irrigation. The recycled or treated water would be used as an alternative to fresh water. In the current study, the impact of various organic amendments was studied to mitigate the toxic effects of pollutants present in wastewater by cultivating maize as a test crop. The present study comprised five treatments replicated four times with a randomized complete block design under field conditions. In this experiment, the treatments included T1 (treatment 1) = control (wastewater-polluted soil without the application of any amendment), T2 = farmyard manure (FYM) at 2.5 tons ha-1 (hectare-1), T3 = FYM at 5.0 tons ha-1, T4 = compost at 2.5 tons ha-1, and T5 = compost at 5.0 tons ha-1. The application of FYM at 5.0 tons ha-1 (T3) was recorded as being the most effective as the maximum improvement was observed in soil characteristics such as pH, electrical conductivity (EC), sodium adsorption ratio (SAR), and organic matter, and for T3, these were 7.33, 2.22 dS m-1, 8.16, and 0.94%, respectively. T3 remained most superior in reducing the concentration of heavy metals in the soil; for example, lead, cadmium, nickel, and arsenic for T3 were 8.64, 1.34, 10.44, and 2.25 mg kg-1 (milligrams per kg), respectively. Maximum fresh biomass (fodder yield) of 9.98 tons ha-1 was harvested when FYM was applied at 5.0 tons ha-1 to the soil compared to 6.2 tons ha-1 in the control plot. The highest contents of nitrogen (1.20%), phosphorus (0.41%), and potassium (3.97%) were observed in maize plants for T3. In maize plants (T3), the concentration of lead, cadmium, nickel, and arsenic was reduced to levels of 1.92, 0.23, 2.28, and 1.25 mg kg-1, respectively. Therefore, it can be concluded from the findings of the experiment that the application of FYM significantly reduced heavy metal concentrations and improved soil health, along with maize crop growth and productivity.

Synbiotic effects of Lactobacillus plantarum CMT1 and Morinda citrifolia on the growth performance and disease resistance of whiteleg shrimp

This study assesses the effects of a prebiotic derived from Morinda citrifolia (noni fruit) extract and a probiotic of Lactobacillus plantarum CMT1 alone and in combination on the survival, growth performance, digestive enzymes, and disease resistance of whiteleg shrimp. A total of 1200 juvenile shrimp were randomly allocated to four treatments: control (not supplemented with noni fruit extract or L. plantarum CMT1), Treatment 1 (TRT1) (supplemented with 1 % noni fruit extract), Treatment 2 (TRT2) (supplemented with 108 CFU/kg L. plantarum CMT1), and Treatment 3 (TRT3) (supplemented with 1 % noni fruit extract and 108 CFU/kg L. plantarum CMT1). After 56 days of feeding, the growth indices of the TRT3 group were statistically larger than the other treatments (P < 0.05). Shrimp in the three treatment groups demonstrated significantly enhanced survival compared to those in the control group (P < 0.05), but no significant differences were observed among these three groups (P > 0.05). Shrimp fed the TRT3 diet had the lowest feed conversion rate, which was statistically significant compared to the other groups. Shrimp in the TRT3 group also had significantly higher amylase and protease levels than the control group. In addition, the use of fruit extract or L.plantarum CMT1 alone and in combination significantly increased shrimp survival after exposure to Vibrio parahaemolyticus, with the TRT3 group recording the highest value. The results indicate that a synbiotic of M. citrifolia extract and L.plantarum CMT1 could be used in shrimp aquaculture to promote animal development and health.

Effect of supplementation of cactus (Opuntia ficus-indica) cladodes, Acacia saligna, wheat bran and cotton seed cake on feed intake, digestibility, growth and carcass characteristics of goats

The objective of this study was to evaluate the effect of supplementation of cactus (Opuntia ficus-indica) cladodes, Acacia saligna, wheat bran and cotton seed cake on growth, digestibility, intake and carcass characteristics of goats. A randomized complete block design was used in the experiment with 24 yearling central highland goats with an initial body weight of 15.6 - 16.1kg. The same amount of grass hay (GH) + 150 gDM/head/day wheat bran (WB) was given to all animals. The experimental diets consisted of 80 cotton seed cake (CSC) as treatment 1 (T1), 45CSC +160 cactus cladodes (CC) as T2, 45CSC+ 80 Acacia saligna (AS) as T3, and 45CSC+80CC+40AS as T4 (gram dry matter: DM, per day per goat), Data were gathered on the goats' growth, digestibility, intake, and carcass of major organs, edible and nonedible organs. The consumption of dry matter and organic matter was higher in goats fed T2 and T4 than in the T1 group. The DM, organic matter (OM) and crude protein (CP) digestibility, average daily body weight gain and feed conversion efficiency were higher in T4 and T3 goats when compared to T2 goats. Goats fed on T4 had higher hot carcass weight and dressing percentage on slaughter body weight basis than T2, T3, and T1 supplemented goats. Generally, the experimental diets improved goats’ performance in descending order (T4 &gt; T3 &gt;T1 &gt;T2). Supplementation of T4 (replacement of 35 g DM of cotton seed cake per day by 40g of Acacia saligna and 80g of cactus cladodes on dry matter bases) could be recommended to improve goat performance.

Does Pelleted Starter Feed Restriction and Provision of Total Mixed Ration Ad Libitum during Weaning Influence the Behavior of Dairy Calves?

Currently, in dairy farming, there is growing concern for the welfare of calves during the critical period between the separation from their dams and weaning. During weaning, rationed feeding is a practice used to improve feed efficiency and control the calves’ growth, but it could also have negative consequences associated with hunger and feed restriction behavior. One such consequence could be the performance by calves of stereotyped behaviors indicative of poor welfare, such as non-nutritive oral behaviors. We hypothesized that making a Total Mixed Ration (TMR) available to calves, in addition to the standard pelleted starter diet, thanks to its structural and nutritional characteristics, could help to focus the oral behavior of the subjects towards nutritional activities and therefore limit the development of stereotyped behaviors, even when the amount of starter is restricted. To test this hypothesis, 30 female Holstein calves (equipped with an accelerometer based on an ear tag), were randomly assigned to one of three treatments: a control diet (CTR) with an ad libitum calf starter but without TMR; Treatment 1 (TRT1) with both ad libitum calf starter and ad libitum TMR; Treatment 2 (TRT2) with ad libitum TMR and a restricted amount of a calf starter (50% of the intake starter of the control group day by day). All animals were kept in individual cages equipped with a slow-flow teat bucket apparatus for milk feeding and with access to separated buckets (one for drinking water, one for the starter, and one for the TMR) placed on the outside of the front gate of each cage. Sucking behavior, as well as resting, ruminating and activity behavior, was recorded individually from 7 days of life to weaning (63 d of age) by an automated monitoring system based on ear-tag accelerometers (SCR eSense, Allflex, Irving, TX, USA). The results showed that in the CTR group, there was a greater sucking activity compared to the TRT1 group (26.25 min/head/day vs. 16.83 min/head/day, p = 0.0181), while the TRT2 group showed intermediate values (20.41 min/head/day). We hypothesized that this increased sucking activity may be explained by the oral activity directed at sucking the Milk Bar tube observed only in CTR calves after complete consumption of available milk and could indicate a higher stress level than in the TRT1 group. The time spent resting was significantly lower for the CTR group compared to the TRT1 group (9.20 h/day vs. 11.15 h/day, p = 0.0049) while the TRT2 group was in an intermediate situation (10.65 h/day). Furthermore, the increase in time dedicated to rest observed in TRT1, in light of the good vitality of the calves shown by the daily patterns of resting behavior and daily activity, also seems to suggest an improvement in welfare conditions compared to calves receiving pelleted starter alone. Based on these results, we can deduce that providing TMR ad libitum in the diet of weaning calves could be an effective strategy to improve calf welfare due to the reduction in stereotyped oral activity. However, further studies are needed to establish threshold values useful for distinguishing physiological from pathological resting times in weaning calves raised in individual cages.

483 DMI, gastrointestinal tract fermentation and permeability, and white blood cell responses in beef heifers provided post-ruminal yeast cell wall extract following feed restriction

Abstract The objectives of this study were to 1) evaluate gastrointestinal fermentation characteristics and permeability, and white blood cell concentrations as beef heifers recovered from a feed restriction (FR) challenge, and 2) determine whether post-ruminal provision of a yeast cell wall extract (YCW) modulated responses. Ruminally cannulated beef heifers (n = 8) were used in a 2 × 2 crossover design. Treatments (TRT) included an abomasal infusion of a placebo (PLC; maltodextrin) or YCW derived from Saccharomyces cerevisiae (2 g/dose) infused at 0600 and 1800 h. Heifers were subject to 5-d of FR (offering 30% of ad libitum DMI) followed by five 5-d recovery phases (REC1, REC2, REC3, REC4, and REC5). Daily DMI, and rumen, fecal, and blood samples were collected on d 5 of FR, REC1, REC3, and REC5 with an additional collection on d 2 of REC1. Total gastrointestinal and post-ruminal permeability were measured using a ruminal dose of Cr-EDTA and an abomasal dose of Co-EDTA, respectively, during FR, REC1, REC3, and REC5 with concurrent urine collection. Data were analyzed to determine the effects of YCW provision, day, and the 2-way interaction. There were no TRT or TRT×day effects for any variables except DMI (interaction, P = 0.04), where DMI did not differ during the FR challenge; however, heifers provided YCW had a greater increase by REC1 compared with PLC heifers without any means differing. DMI progressively increased from FR, to REC1, REC2, and REC5. Ruminal acetate concentration increased (P &amp;lt; 0.01) from FR (45.4 mmol/L) to REC1 d5 (60.1 mmol/L) and increased further to REC3 (67.3 mmol/L) with no change thereafter (68.3 mmol/L in REC5). Ruminal propionate concentration increased (P &amp;lt; 0.01) from FR (14.5 mmol/L) to REC1 d2 (27.7 mmol/L) and was not different thereafter. Similarly, butyrate concentration increased (P &amp;lt; 0.01) from FR (7.9 mmol/L) to REC1 (d 5; 15.0 mmol/L) and was not different thereafter. Fecal acetate, propionate, and butyrate concentrations were not affected by day (P ≥ 0.12). Total gastrointestinal and post-ruminal permeability were greatest during FR (P &amp;lt; 0.01; 2.6% and 2.2% of the infused marker was excreted in urine, respectively) and decreased to 1.6% and 1.1%, respectively, in REC3 followed by an increase in REC5 for total (2.0% of infused) but not post-ruminal (1.0% of infused) permeability. The concentration of neutrophils (P &amp;lt; 0.01) was greatest on REC1 d2 (4.84 ×106 μmol/mL) and eosinophil concentration (P &amp;lt; 0.01) was greatest during FR (0.53 ×106 μmol/mL), least on d 2 of REC1 and increased on d 5 of REC1 but was not different thereafter. WBC (P &amp;lt; 0.01) gradually decreased (P = 0.02) from FR and REC1 d2 to REC3 and REC5. Post-ruminal provision of YCW may accelerate increases in DMI early in the recovery from FR, yet treatment did not modulate ruminal or fecal SCFA, blood concentrations, or gastrointestinal permeability.

Biofortification in garden peas through multi-micronutrient formulations

Soil micronutrient deficiencies lead to crops with low essential element concentrations, affecting human health through micronutrient malnutrition. Effective practices, like foliar nutrient application, improve crop quality and reduce malnutrition. The garden pea (Pisum sativum L. var. hortense) is cultivated worldwide for its nutritional value and such nutrient-rich crops, through agronomic biofortification, offer a sustainable solution to global health issues by addressing micronutrient deficiencies. Four liquid micronutrient formulations [Treatment 1 (T1), Treatment 2 (T2), Treatment 3 (T3), and Treatment 4 (T4)] were prepared using either water or vermiwash as a carrier, with variations that included the presence or absence of plant growth regulators (GA3 + NAA)] and evaluated along with commercially available formulations [Arka Vegetable Special (T5) and ProKissan (T6)]. Micronutrient formulations, particularly T3, demonstrated notable effects on various parameters, including plant height, biomass, root characteristics, pod weight, and micronutrient contents in seeds of garden pea var. Kashi Nandini. T3 significantly outperformed other formulations in promoting plant growth, resulting in higher values for plant height, biomass, branches per plant, nodule mass, root biomass, surface area, volume, and density. Yield parameters such as pod length, weight, number of pods, and seeds per pod were also positively influenced by micronutrient treatments, with T3 leading to the highest overall yield, with a 24.09 % increase per plant and a 13.39 % increase per hectare compared to the control. Additionally, foliar application of micronutrients increased the concentration of copper, zinc, iron, and manganese in seeds, positively impacting seed quality. Quality parameters, including total soluble solids, protein, total phenol, and total flavonoid contents, were significantly improved by micronutrient treatments, with T3 showing the most favorable outcomes. Texture analysis indicated that peas treated with T3 had lower firmness values, suggesting maintained tenderness and sweetness. Correlation analysis revealed strong positive associations between various growth parameters, yield traits, and micronutrient contents. Overall, foliar micronutrient application proved to be a valuable biofortification strategy for enhancing the performance and quality of garden peas.

Effect of supplemented paprika oleoresin solution on the physicochemical properties and shelf-life of boiled pork sausages with nitrite reduction.

This study was performed to evaluate the quality characteristics of reduced-nitrite boiled pork sausages (BPSs) with paprika oleoresin solution (POS) to compensate for the reduced sodium nitrite (NaNO2). POS was prepared by diluting paprika oleoresin with sunflower seed oil at a ratio of 1:20. BPSs were subjected to four different treatments: reference (REF), BPS added with 150 ppm NaNO2; control (CTL), BPS added with 37.5 ppm NaNO2; treatment 1 (TRT1), BPS added with 37.5 ppm NaNO2 and 0.1% POS; treatment 2 (TRT2), BPS added with 75 ppm NaNO2 and 0.1% POS). The pH values of CTL were lower than those of other treatments. The a* values of TRT1 were higher than those of CTL, and those of REF were lower than those of TRT1 and TRT2. The b* values of TRT1 and TRT2 were higher than those of REF and CTL. The total plate counts of CTL were the highest among all treatments, and Enterobacteriaceae counts of CTL and TRT1 on the 14th day were higher than those of REF and TRT2. The combination of 75 ppm NaNO2 and 0.1% POS to BPS during storage had an antimicrobial effect similar to that of adding 150 ppm NaNO2. Thus, POS can be used to reduce the use of NaNO2 in meat products.

Evaluation of substrates for optimizing vermicomposting products

The high global market value of fresh mushrooms implies high importance of spent mushroom substrate (SMS) as a by-product that poses environmental challenges, if not properly treated. Reported studies demonstrate the positive effects of SMS on earthworm growth and reproduction, particularly when combined with other substrates such as cow dung (CD). This study utilized SMS and CD as substrates in varying ratios. A total of 375 young non-clitellated Eisenia fetida were randomly assigned to plastic containers, ensuring similar average individual worm weight, and maintained at 50% to 60% moisture. Weekly observations were made on earthworm average weight, cocoon production, and hatchling count. The growth and reproduction of earthworms differed significantly among treatments, with Treatment 3 (T3) (50:50 SMS and CD) showing the highest growth and Treatment 5 (T5) (0:100 SMS and CD) the lowest. Changes in pH, EC, total Kjeldahl nitrogen (TKN), total organic carbon (TOC), C/N ratio, and total available phosphorus (TAP) were observed over the experimental period, indicating dynamic nutrient dynamics within the substrates. The exchangeable potassium decreased with increasing proportions of CD, while the exchangeable sodium content showed variation across treatments. The observed variations can be attributed to differences in initial substrate composition and microbial activity during vermicomposting.

Astaxanthin supplementation ameliorates simulated heat stress by regulating physio-biochemical responses in Sirohi goats.

The present study was undertaken to assess the ameliorative effect of dietary supplementation of astaxanthin in Sirohi goats under simulated heat stress conditions. Eighteen healthy female Sirohi goats were divided equally into three groups (n = 6): Heat-Stressed Control (HSC), Treatment 1 (T1), and Treatment 2 (T2). During the experiment, goats in the T1 group were supplemented with astaxanthin at the rate of 25mg/animal/day, while those in the T2 group received supplementation of 50mg/animal/day. The experiment was conducted for 42 days: 14 days of acclimatization period, next 21 days animals were exposed to 42ºC for 6h from 09:00h to 15:00h and 7 days of recovery period. On a daily basis, we recorded the physiological responses of goats and collected environmental data at the experimental site. Blood samples were collected 0 and 14th days of acclimatization, on 1st, 6th, 11th, 16th and 21st day of heat exposure and on the 7th day of the recovery period. The rectal temperature and respiration rates of the treatment groups were lower than those of the HSC group during the exposure period. Heat stress in the supplemented groups was associated with reduced levels of hepatic enzymes such as AST and ALT. Serum urea, creatinine and albumin levels were significantly (P < 0.05) different between control and treatment groups. It was thus concluded that dietary inclusion of antioxidant astaxanthin can ameliorate induced thermal load as evident from changes in physio-biochemical parameters in the Sirohi goats, that was more prominent at 50mg/ animal/day than 25mg/ animal/day.

Growth performance of durian based on crop water requirement (ETc) using irrigation system

Water use for agricultural production in water scarcity regions requires precise irrigation water for sustainable irrigation management. The correct amount of irrigation water should be applied to ensure the survival of plants. Currently, farmers apply irrigation without considering the actual amount of the crop water requirement (ETc), which may lead to over or under-irrigation. These problems may cause water logging, crop stress, reduced yield and inefficient farm management. Durian (Durio zibethinus) is an important economic crop of Southeast Asian countries, including Thailand, Malaysia, and Indonesia. Lately, durian plantation has been increasing in Malaysia with innovative and sustainable approaches through irrigation or fertigation. The growth of durian is highly affected by water and nutrients given to the plants. This paper highlights the effect of precise irrigation through durian water requirement. Hence, this study aims to compare the difference in growth performance between existing practices (irrigation without ETc) and irrigation based on ETc. The study was conducted in the durian plantation at Sri Lalang, Kluang, Johor. There were two treatments tested on the durian, which are treatment 1 (T1) existing practice (irrigation without ETc) and treatment 2 (T2), irrigation based on ETc. The experimental design for this experiment is a Randomized Complete Block Design (RCBD) with four (4) blocks, and four trees for each treatment per block. The data collection includes the height of the tree, canopy width, girth’s diameter, node distance, leaf length and leaf weight. These data were analysed using ANOVA and LSD. Data was collected from April until November 2020. There was a significant difference in node distance from April until September. However, there were no significant differences for other growth parameters, suggesting precise crop water requirement can save water and minimize cost for the whole irrigation management.

Analysis of the UV filter Benzophenone-3 assimilation in Crossostrea gigas oysters post-exposure in a controlled environment by LC-MS/MS

Benzophenone-3 (BP-3), utilized as a UV filter in cosmetic products, is an emerging contaminant that constitutes a threat to natural resources and environmental health. This study investigated the assimilation of the UV filter BP-3 in Crassostrea gigas oysters collected in Florianópolis, Santa Catarina, Brazil. Lyophilized oyster tissue extracts were prepared using the QuEChERS method, and LC-MS/MS was employed to determine the BP-3 concentration in the samples. The method was applied to specimens intentionally exposed to two concentrations of the contaminant, for different periods of exposure (1 and 7 days). Samples from treatment 1 (T1) were exposed to a concentration of 1 μg L−1 of the BP-3 standard, and samples from treatment 2 (T2) were exposed to a concentration of 100 μg L−1 of the BP-3 standard. The results revealed rapid absorption of BP-3, with an increase of 126% for lower concentrations, reaching 1.13 μg of BP-3 per gram of oyster tissue, and 17% for higher concentrations, reaching 34.6 μg of BP-3 per gram of oyster tissue after 7 days. The presence of BP-3 even in samples not directly exposed to the contaminant indicates its widespread environmental distribution. The rapid bioaccumulation suggests the need to consider seasonal variations, such as increased tourism in the summer. The validated analytical method demonstrated efficacy in quantifying BP-3, providing an integrated approach for long-term monitoring of pollution levels and their dynamic variations over time. In addition, variation in BP-3 levels in the samples may be related to transport patterns influenced by tides and discharges from septic system, highlighting the need to improve wastewater treatment. These findings underscore the necessity for continuous biomonitoring and effective environmental management to safeguard the health of marine ecosystems and humans.

Administration of Nanocurcumin in Mice Models of Endometriosis as an Effort to Improve Folliculogenesis

The purpose of this study is to ascertain how nanocurcumin 0-50 nm affects malondialdehyde (MDA) levels, folliculogenesis, and the quantity of corpus luteum (CL) in a mice model of endometriosis. 24 mice were used in this scientific experiment, and they were split up into 4 treatment groups; positive control (C+) as mice model of endometriosis, Treatment 1 (T1) as mice model of endometriosis given nanocurcumin 0-50 nm (2.5 mg/KgBW) PO, Treatment 2 (T2) mice given nanocurcumin (5 mg/KgBW) and Treatment 3 (T3) as mice model of endometriosis treated with nanocurcumin (10 mg/KgBW). The nanocurcumin was administered for 14 days. The findings demonstrated that, out of all treatment groups, T3 had the lowest MDA level (20.78±4.58 ng/ml) and statistically significant (p&lt;0.05) compared to C+, T1 and T2. Significant differences (p&lt;0.05) were observed in the number of primary, secondary, and tertiary follicles at T3, from C+, T1, and T2, according to the folliculogenesis profile. Although the number of Graafian follicles tended to grow, there was no discernible difference between the number of Graafian follicles and the CL. It can be concluded that the administration of nanocurcumin for 14 days decreased MDA levels and increased the folliculogenesis profile. Administration of nanocurcumin at a dose of 10 mg/KgBW caused a decrease in MDA levels and an improvement in the folliculogenesis profile. Thus, administering nanocurcumin could improve the quality of folliculogenesis in endometriosis sufferers and improve reproductive health.

Effects of Dietary Inclusion of Angelica gigas Nakai root extract on the Growth Performance, Hematological and Serum Biochemical Parameters in Broilers

The study aimed to evaluate the impact of dietary supplementation with Angelica gigas Nakai (AGN) root extract on growth performance, hematological indices, and serum biochemical parameters in broiler chickens. A total of 320 straight-run Cobb broiler chicks from a commercial hatchery were distributed among four treatment groups: Basal diet (BD) as the Control; Treatment 1 (T1): BD + 2 g/kg AGN; Treatment 2 (T2): BD + 4 g/kg AGN; and Treatment 3 (T3): BD + 8 g/kg AGN), each comprising eight replicates with 10 birds per replicate. The supplementation of AGN resulted in dose-dependent improvements (P &lt; 0.05) in body weight, gain, and feed efficiency. On both day 21 and day 35, increasing AGN dosage in the diet led to a significantly higher (P &lt; 0.05) values of red blood cells (RBCs), white blood cells (WBCs), hemoglobin (Hb), and packed cell volume (PCV). By day 21, AGN supplementation dose-dependently decreased (P &lt; 0.05) serum alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), urea, and creatinine levels. Meanwhile, AGN dose escalation correlated with a notable increase (P &lt; 0.05) in serum total protein (TP), albumin, and globulin levels. On day 35, increasing AGN levels led to a significant reduction (P &lt; 0.05) in serum AST and ALT activity, along with lowered serum glucose, cholesterol, triglycerides, urea, and creatinine levels. In conclusion, AGN supplementation enhanced growth performance and positively influenced hematological indices and serum biochemistry profiles in broiler chickens. The study confirms the safe and effective utilization of AGN at an 8 g/kg (0.8 %) feed additive dosage to optimize broiler performance. These findings provide valuable insights into the potential benefits of AGN in poultry nutrition.

Temporal Association Rule Mining: Race-Based Patterns of Treatment-Adverse Events in Breast Cancer Patients Using SEER-Medicare Dataset.

Disparities in the screening, treatment, and survival of African American (AA) patients with breast cancer extend to adverse events experienced with systemic therapy. However, data are limited and difficult to obtain. We addressed this challenge by applying temporal association rule (TAR) mining using the SEER-Medicare dataset for differences in the association of specific adverse events (AEs) and treatments (TRs) for breast cancer between AA and White women. We considered two categories of cancer care providers and settings: practitioners providing care in the outpatient units of hospitals and institutions and private practitioners providing care in their offices. We considered women enrolled in the Medicare fee-for-service option at age 65 who qualified by age and not disability, who were diagnosed with breast cancer with attributed patient factors of age and race, marital status, comorbidities, prior malignancies, prior therapy, disease factors of stage, grade, and ER/PR and Her2 status and laterality. We included 141 HCPCS drug J codes for chemotherapy, biotherapy, and hormone therapy drugs, which we consolidated into 46 mechanistic categories and generated AE data. We consolidated AEs from ICD9 codes into 18 categories associated with breast cancer therapy. We applied TAR mining to determine associations between the 46 TR and 18 AE categories in the context of the patient categories outlined. We applied the spark.mllib implementation of the FPGrowth algorithm, a parallel version called PFP. We considered differences of at least one unit of lift as significant between groups. The model's results demonstrated a high overlap between the model's identified TR-AEs associated set and the actual set. Our results demonstrate that specific TR/AE associations are highly dependent on race, stage, and venue of care administration. Our data demonstrate the usefulness of this approach in identifying differences in the associations between TRs and AEs in different populations and serve as a reference for predicting the likelihood of AEs in different patient populations treated for breast cancer. Our novel approach using unsupervised learning enables the discovery of association rules while paying special attention to temporal information, resulting in greater predictive and descriptive power as a patient's health and life status change over time.

Effect of coconut shell extract on the growth performance and some haemato-biochemical parameters of broiler chicken

This experiment was carried out at Sumitra Research Institute, Gujarat, India to evaluate the effect of coconut shell extract on the growth performance and some haemato-biochemical parameters of broiler chicken. 240 – 1 day old Hubbard broiler chicks of mixed sex were randomly distributed to six treatments with six replicates containing ten birds each in a completely randomized design. Birds in treatment 1(T1) was fed standard diet with no coconut shell extract; T2: standard diet with 1.0 mL coconut shell extract per liter of water; T3: standard diet with 2.0 mL coconut shell extract per liter of water and T4: standard diet with 3.0 mL coconut shell extract per liter of water. Standard diet was formulated according to the nutritional needs of broilers. The study lasted for fifty-six day and birds were offered fresh clean water and feed ad libitum. Phenols (410.3 mg/g-1), tannins (98.21 mg/g-1), alkaloids (100.6 mg/g-1), flavonoids (309.5 mg/g-1), saponins (71.4 mg/g-1) and steroids (28.7 mg/g-1) were identified coconut shell extract. Overall weight gains of birds fed T3 (2506.3 g) and T4 (2527.6 g) had a numerical and a remarkable significant improvement if feed conversion ratio from 1.92 to 1.59 compared to T2 (2210.0 g) and T1 (1996.1 g). Mortality was only recorded among birds in T1 (2.00 %) (p &lt; 0.05). Pack cell volume, red blood cell, white blood cell, haemoglobin, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentrations were influenced (p &lt; 0.05) by the treatments. However, values were within the normal range for healthy birds. Total protein, albumin and globulin values were higher in T2, T3 and T4 except for alanine phosphatase, aspartate transaminase and alanine transaminase values which were not significantly (p &gt; 0.05) different among the treatment. Total cholesterol was higher (p &lt; 0.05) in T1 relative to the other treatments. It was concluded that coconut shell extract can be fed to broilers up to 3.0 mL without causing any negative effect on the health status of animals.

297 Effects of plasma zinc concentration on longissimus thoracis metabolic status of beef steers

Abstract The objective of this study was to examine the role of Zn status on muscle glucose and other metabolites. Angus steers [n = 144; body weight (BW) = 525 ± 30 kg] with varying plasma Zn concentration and implant status served as the initial pool for this secondary experiment. Steers were assigned to one of two implant (IMP) treatments: no implant (NO) or Component TE-200 (TE-200; Elanco, Greenfield, IN) on d 0. Zinc was supplemented as ZnSO4 at 0 mg Zn/kg dry matter (DM; analyzed 54 mg Zn/kg DM), 30 mg Zn/kg DM, or 100 mg Zn/kg DM, starting 60 d before implant day. Steers were fed via GrowSafe bunks (GrowSafe Systems Ltd., Airdie, AB, Canada), and steer was experimental unit. Steers were fed in two blocks with a 14-d stagger for sample logistics. Blood and muscle biopsies of the longissimus thoracis were collected on d 40 after implant, a minimum of 2 h post-feed delivery. Plasma Zn was quantified via ICP-OES and 144 samples were stratified into quantiles by plasma Zn concentration. Samples (n = 12 low and 12 high from NO and TE-200 groups) were identified and designated as low plasma Zn (LOW, 1.1 mg Zn/L average) and high plasma Zn (HI, 1.6 mg Zn/L average) treatments (TRT). Muscle samples from these 48 steers were homogenized and derivatized for subsequent analysis via gas chromatography-mass spectrometry (GCMS) for non-targeted metabolomic analysis. Data were analyzed as a complete randomized design using the MIXED procedure of SAS 9.4 (SAS Inst. Inc., Cary, NC) with fixed effects of TRT, IMP, BLOCK, and TRT×IMP. A TRT×IMP effect was observed for muscle glycine (P = 0.02) where LOW/IMP was similar to HI/NO but had greater glycine concentrations than LOW/NO and HI/IMP. There was a tendency for a TRT×IMP (P = 0.07) effect where LOW/IMP and HI/NO tended to have greater concentrations of hydroxyisovaleric acid. Given the role of glycine in protein synthesis and hydroxyisovaleric acid in leucine metabolism these data suggest differential protein responses to implants in cattle of lesser vs. greater plasma Zn concentrations. Hydroxybutyric acid, a ketone body which can be utilized for energy, tended to be greater in muscle of steers receiving an IMP (P = 0.09). Contrary to our hypothesis that greater plasma Zn would support differential muscle glucose metabolism, no effects of plasma Zn TRT or IMP were noted for glucose, lactate, and other detected metabolites. Both LOW and HI plasma Zn concentrations were still considered adequate, and future research should explore the impact of distinctly deficient and adequate plasma Zn concentration on glucose metabolism pathways in muscle.

The effects of raja banana (Musa acuminata) peel extract on body weight, body mass index, body fat percentage, and visceral fat mass in male rats with obesity

&lt;p&gt;&lt;strong&gt;&lt;em&gt;Background: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;Obesity is a risk factor for metabolic syndrome which can increase mortality. Obese sufferers often fail to lose body weight (BW) through non-pharmacological therapy. Obesity synthetic drugs can cause side effects, so natural ingredients are needed as alternative therapies.&lt;/em&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Objectives: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;This study aims to determine the effect of raja banana peel extract (RBPE) on BW, body mass index (BMI), body fat percentage (BFP), and visceral fat mass in obese male rats.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Methods: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;The research subjects were 30 male Wistar rats weighing 125-200 g, aged eight weeks. Obesity was induced by being given high-fat high fructose (HFHFr) feed for 28 days. Rats were randomized and divided into five groups: the negative control group (C-) was given standard feed and distilled water, the positive control (C+) was given standard feed and orlistat, treatment 1 (T1), treatment 2 (T2), and treatment 3 (T3). Which were given standard feed and RBPE doses of 200 mg/kgBW/day, 400 mg/kgBW/day, and 800 mg/kgBW/day. Data before and after the induction of obesity were analyzed using paired t-tests. BW, BMI, and visceral fat mass were analyzed using the One-Way Analysis of Variance (ANOVA) and Repeated Measure ANOVA tests. BFP was analyzed using the Kruskal-Wallis test and the Friedman test.&lt;/em&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Results: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;RBPE can significantly reduce BW (p=0.026), BMI (p&amp;lt;0.001), and BFP (p&amp;lt;0.001). However, all groups had no significant difference in visceral fat mass (p=0.187). T3 was the group with the lowest average BW, BMI, BFP, and visceral fat mass although the highest weight loss during the intervention period occurred in C+.&lt;/em&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;&lt;strong&gt;&lt;em&gt;Conclusions: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;RBPE has the potential as an alternative therapy for obesity because it can reduce BW, BMI, and BFP. Future studies can investigate the effect of RBPE on other obesity parameters such as lipid profiles.&lt;/em&gt;

EFFECTS OF DIETARY INCLUSION OF VARIED LEVELS OF BUTYRIC ACID AS ANTIBIOTIC ON THE PERFORMANCE OF TURKEY POULTS

The effects of butyric acid supplemented diets on growth performance of turkey poults were examined in a 49-day experiment using one hundred and sixty (160) (one-day old) Nicholas turkey poults. The experimental design was a Completely Randomized Design. Poults were brooded for 7 days, after which they were allotted to 4 dietary treatments with 5 replicates of 8 birds per replicate. Treatment 1(T1) was the basal diet with no supplement while treatments 2 (T2), 3 (T3), and 4(T4) were supplemented with antibiotics, 0.2% butyric acid and 0.4% butyric acid respectively. Feed was offered ad-libitum. Final weight and weight gain of poults fed control, antibiotics and 0.2% butyric acid supplemented diets were similar but significantly (p&lt;0.05) higher than birds fed 0.4% butyric acid diet. Significant higher feed intake was observed in birds fed control and antibiotics diets while the least was recorded in birds fed 0.4% butyric acid diet. It was observed that 0.2% butyric acid appears to be a viable alternative to antibiotics growth promoter in turkey diets without any detrimental effect on the productive performances.

Conch Shell (Turbinella pyrum) Powder: A Potential Marine Biological Source of Calcium and Some Trace Minerals for Growing Crossbred Calves.

The present study was conducted to evaluate the effect of feeding conch shell (Turbinella pyrum) powder (either fresh or calcined) as a marine organic source of calcium (Ca) supplemented in the diet of crossbred calves on voluntary intake, growth performance, and blood biochemistry in growing crossbred Jersey calves. A growth trial of 90days was conducted on 15 Jersey crossbred female calves (Av. weight, 70.68 ± 2.90kg; Av. age, 197.73 ± 12.40days), equally divided into three groups of 5 animals each, i.e., control (T0), treatment 1 (T1), and treatment 2 (T2). All animals were fed total mixed ration (TMR) prepared with a concentrate mixture, chaffed paddy straw, and green fodder at the ratio of 40:30:30 on DM basis. Calves under the control group were fed with TMR containing a standard mineral mixture having dicalcium phosphate (DCP) as a Ca source. Calves under T1 group were supplemented with TMR containing fresh conch shell powder (FCSP), and T2 calves were fed with TMR containing conch shell calcined powder (CSCP) as Ca source. We observed 11.66% increase (p < 0.01) in Ca concentration in CSCP compared to FCSP. The concentration of minerals like Mg, Co, Mn, and Fe was enhanced in CSCP compared to the FCSP. However, the calcination process of fresh conch shell powder (FCSP) reduced the concentration of Cu, and Zn. The Ca/P ratio was estimated as 2.11, 2.06, and 2.10 in T0, T1, and T2 diets, which could be considered ideal for calf ration. Calves under T1, and T2 groups consumed significantly (p < 0.001) greater amounts (g/kg W0.75) of DM and CP compared to T0. However, increased voluntary intake did not translate into increased body weight gain (kg), and feed conversion ratio (kg DMI/kg gain) in T1 and T2 groups in comparison to T0. We observed similar blood glucose, urea, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine transaminase (ALT) concentration among the three treatments. Ca, and P levels in blood plasma were also identical among the three groups. The digestibility of Ca was increased significantly (p = 0.01) in FCSP (T1)- and CSCP (T2)-treated calves compared to control (T0) calves. Similarly, T1 and T2 enhanced P digestibility compared to T0. This first report with short-term experimentation depicted some promising scope for the use of locally available conch shell powder (fresh or calcined form) as a potential source of Ca for feeding to livestock, because these new sources of Ca did not affect intake, digestibility of Ca and P, growth performance, blood chemistry, and liver enzymes negatively in weaned crossbred calves.

Supplementing Broiler Chicken Diet with Uvaria chamae Leaf Meal: Effects on Immune Response, Gut Microbial Population and Growth Performance

The purpose of this experiment was to determine how supplementing Uvaria chamae leaf meal (UCLM) affects growth performance and a few hematological markers of broiler chicken. For a 56-day study, 500 one-day-old (Ross 307) broiler chicks were randomly assigned to five treatments, each consisting of 100 birds. Standard feed was formulated according to the nutritional standards for broilers. Treatment 1 (T1) was fed a standard diet with 0.25 g/kg oxytetracycline while T2, T3, T4, and T5 were provided a standard diet supplemented with UCLM at 5g, 10g, 15g, and 20g, respectively. The treatments had a significant impact on body weight gain, feed conversion ratio and mortality. In contrast, the mortality rate and Escherichia coli counts were higher in T1 and T2 compared to other groups, whereas body weight gain was higher in T2, T3, T4, and T5 compared to T1. Regarding crude fiber digestibility and average daily feed intake, there was no statistically significant difference. The dry matter, crude protein, ether extract, ash digestibility, hemoglobin, packed cell volume, red blood cell, lymphocytes, monocytes, immunoglobulin A, Y, and M and Lactobacillus sp. counts of the birds supplemented with UCLM at 2 g/kg (T2), 4 g/kg (T3), 6 g/kg (T4), and 8 g/kg (T5) were similar but significantly greater than those of T1 (0.25 g/kg oxytetracycline). It was determined that broilers' diets can include up to 20 g/kg of UCLM supplementation without harming the birds' health.
