Development of a Light Intensity Monitoring System in Broiler Chicken Coops Based on Arduino IoT Cloud

The lighting system significantly influences the growth and productivity of broiler chickens, necessitating an efficient tool for monitoring light intensity in chicken coops. This study aims to design and develop an Arduino IoT Cloud-based light intensity monitoring system for broiler chicken coops. The system employs two BH1750 light sensors, positioned inside and outside the coop, to measure light intensity, which is then processed by an ESP32 microcontroller. The collected data is displayed on a 16x2 LCD screen and uploaded in real time to the Arduino IoT Cloud platform for remote monitoring. Testing conducted over a 6-hour period revealed that light intensity inside the coop remained stable at approximately 30 lux from 09:30 to 12:52, while the highest external light intensity reached 400 lux between 12:06 and 14:40, followed by a decrease after 14:50. These findings indicate that the system can assist farmers in timely actions, such as opening or closing coop curtains, through effective monitoring via the Arduino IoT Cloud platform.

Hepatic Transcriptomics of Broilers with Low and High Feed Conversion in Response to Caloric Restriction

Background: In broiler chickens, the efficient utilization of macro- and micronutrients is influenced by various metabolic pathways that are closely linked to feed efficiency (FE), a critical metric in poultry industry, with residual feed intake (RFI) as the preferred proxy. Feed restriction is considered an approach to address the underlying molecular mechanisms of feed conversion. We hypothesized that broiler chickens with divergent RFI subjected to quantitative feed restriction differ in their pattern of molecular pathways for efficient nutrient utilization in liver as post-absorptive tissue. Methods: Cobb 500FF broiler chickens divergent for RFI (n = 112) were feed-restricted from day 9 until market weight at day 33–37 post-hatch. Based on a previous trial, feed restriction levels were set at 92% (low-RFI birds) and 80% (high-RFI birds) relative to the control groups. Transcriptomic analyses of the liver were conducted. Results: Due to the interaction of the RFI group and feeding regimen, a total of 140 to 507 differentially expressed genes were identified for the respective contrasts, with implications for hepatic metabolism and cellular stress response. Although the broilers did not realize their full growth potential under restrictive feeding (12.4% reduced body weight vs. controls, p = 0.094), the gene expression patterns indicate a lower susceptibility to blood coagulation (KNG1, FGG, and FGB), suggesting that controlled and mild feed restriction could lead to health benefits in less feed-efficient broilers. Moreover, FE traits are shown to be linked to cellular detoxification processes (MGST3 and CYP2AC2) and triacylglycerol syntheses (MOGAT1 and LPIN1). Conclusions: Divergent transcriptional profiles between broiler groups under varied caloric conditions indicate potential for optimizing nutritional management strategies.

Assessment of the dietary amino acid profiles and the relative biomarkers for amino acid balance in the low-protein diets for broiler chickens.

Research on low-protein-level diets has indicated that even though the profiles of essential amino acids (EAAs) follow the recommendation for a normal-protein-level diet, broilers fed low-protein diets failed to achieve productive performance compared to those fed normal diets. Therefore, it is imperative to reassess the optimum profile of EAAs in low-protein diets and establish a new ideal pattern for amino acid balance. Furthermore, identifying novel sensitive biomarkers for assessing amino acid balance will greatly facilitate the development of amino acid nutrition and application technology. In this study, 12 dietary treatments [Con(+), Con(-), L&A(-), L&A(+), M&C(-), M&C(+), BCAA (-), BCAA(+), Thr(-), Thr(+), Trp(-) and Trp(+)] were established by combining different EAAs including lysine and arginine, methionine and cysteine, branched-chain amino acid (BCAA), threonine, and tryptophan to observe the growth and development of the broiler chickens fed with low-protein-level diets. Based on the biochemical parameters and untargeted metabolomic analysis of animals subjected to different treatments, biomarkers associated with optimal and suboptimal amino acid balance were identified. Growth performance, carcass characteristics, hepatic enzyme activity, serum biochemical parameters, and breast muscle mRNA expression differed significantly between male and female broilers under different dietary amino acid patterns. Male broilers exhibited higher sensitivity to the adjustment of amino acid patterns than female broilers. For the low-protein diet, the dietary concentrations of lysine, arginine, and tryptophan, but not of methionine, cystine, or threonine, needed to be increased. Therefore, further research on individual BCAA is required. For untargeted metabolomic analysis, Con(+) was selected as a normal diet (NP) while Con(-) represented a low-protein diet (LP). L&A(+) denotes a low-protein amino acid balanced diet (LPAB) and Thr(+) represents a low-protein amino acid imbalance diet (LPAI). The metabolites oxypurinol, pantothenic acid, and D-octopine in birds were significantly influenced by different dietary amino acid patterns. Adjusting the amino acid profile of low-protein diets is required to achieve normal growth performance in broiler chickens fed normal-protein diets. Oxypurinol, pantothenic acid, and D-octopine have been identified as potentially sensitive biomarkers for assessing amino acid balance.

Perches used as environmental enrichment influence fast-growth broilers' biomechanics and locomotor morphometry at the age of 42 days.

Currently available conventional breeding methods for broilers often result in impaired biomechanics and skeletal growth for the animals. The addition of environmental enrichment is an alternative which can help alleviate these effects. This study examines the effects of environmental enrichment on biomechanics, morphometry, and bone mass of broilers across various age groups. In total, 112 Cobb 500 chicks (50% male and 50% female) were used in a completely randomized design experiment, with 56 broilers per treatment (T1 and T2), carried out in subdivided plots. Each plot was subjected to a different treatment, as follows: all plots were subjected to the treatments (T1 = environmental enrichment and T2 = no environment enrichment) and the sub-plots held the broilers' age groups (1, 7, 14, 21, 28, 35 and 42 days old). Eight broilers were euthanized on a weekly basis for two production cycles in order to perform morphometric (diameter and length) and biomechanical analysis of the response variables. These measurements were performed on the femur and tibia. Birds were subjected to classical linear fixed effects model and compared through Tukey's mean test. Significant interactions between environmental enrichment and broiler age were noticed, particularly at 42 days, which displayed bone development for all variables under study. Except for the length of the femur of broiler chickens (p = 0.4638). Therefore, simple effects will not be evaluated. Environmental enrichment had a notable impact on tibia length (p = 0.0035), femur weight (p = 0.0014), and tibia weight (p<0.0001) at 42 days, indicating a favorable effect on skeletal growth in broilers. Enrichment resulted in a 1% increase in femur inertia, a 2% rise in tibia inertia, and a 1% enhancement in ultimate bending stress for both bones, displaying improved structural integrity and durability. Beneficial changes in bone morphology and biomechanics were observed at 42 days after enrichment.

Partial replacement of soybean with local alternative sources: effects on behavior, cecal microbiota, and intestinal histomorphometry of local chickens

Interest in partially replacing soybean meal in poultry diets with alternative protein sources such as agri-industrial by-products and black soldier fly (BSF, Hermetia illucens) has gained significant attention due to sustainability concerns. This study aimed to evaluate the effects of broiler diets in which soybean meal was partially substituted with agri-industrial by-products with or without BSF larvae meal, on the behavior, intestinal histomorphometry, and microbiome profile of a local broiler chicken strain. There were three dietary treatments. (1) A corn-soybean-based diet (Control), (2) a diet in which soybean was partly replaced (SPR) with local agri-industrial by-products, namely sunflower meal, brewers' dried grain, and wheat middlings, and (3) a diet in which BSF (5%) meal was added to SPR (SPR+BSF). Behavior was recorded on days 14, 35, and 49 at the pen level. On day 55, intestinal segments and cecal contents were collected from eight chickens per pen for histomorphometry and microbiome analysis. Dietary manipulations did not affect the behavior of broiler chickens (P &amp;gt; 0.05) suggesting that the experimental diets had no influence on behavior. A significant interaction between the intestinal segment and diets revealed that the SPR and SPR+BSF diets decreased duodenal villus height (VH) compared to the control diet (P &amp;lt; 0.05). However, this effect was not consistent across all of intestinal segments. Diet did not affect villus height to crypt depth ratio (VH/CD; P &amp;gt; 0.05), indicating no significant impact on the absorptive capacity of the digestive system. Firmicutes and Bacteroidetes were the dominant phyla in the cecal samples. Colidextribacter and Oscillibacter spp. were more abundant in chickens fed the SPR diet compared to those fed the control diet. The SPR+BSF diet resulted in higher abundance of Rikenella and Colidextribacter spp. compared to the control diet, while Desulfovibrio, Ruminococcus torques group, and Lachnoclostridium were more abundant in the ceca of birds fed the SPR diet than those fed SPR+BSF. In conclusion, replacement of soybean with agri-industrial by-products and BSF larvae meal could regulate the cecal microbiota composition without negatively affecting the behavior and intestinal histomorphometry of the local chickens.

Comparative Effect of Feeding Maiwa and Pearl Millet as Dietary Energy Source for Broiler Chicken

This study compared the effects of feeding broiler chickens, maiwa and pearl millet as dietary energy sources. The effectiveness, performance, and carcass features of broiler chickens given varying amounts of maiwa and pearl millet as dietary energy sources were evaluated in a feeding trial/experiment. The experiment used 200 day-old broiler chickens. The experiment was divided into two phases: starter and finisher. Five experimental meals containing 20 and 23% crude proteins were created for each phase. For T1, T2, T3, T4, and T5, five experimental diets were developed with different inclusion levels of 0, 25, 50, 75, and 100% respectively. In a randomized completely block design (RCBD), each treatment was duplicated four times, with ten birds each replication. Feed and water were provided ad libitum from 2nd to the 9th week of age. The result of the experiment on percentage composition of the experimental diets indicated that crude protein and metabolizable energy are within the range adequate for raising broiler chickens. The daily feed intake values (53.80-57.05g; 120.30-124.35g; 82.79-85.35g) and the daily weight gain values (29.95-33.82g; 41.77-44.66g; 34.22-35.88g) obtained from the performance of broiler chickens revealed non-significant differences among the treatments in the three (3) phases. The dietary treatments had no effect on the carcass and visceral organ parameters of broiler chickens, with the exception of caecal weight and small intestine length, which differed significantly (P≤0.01), with values ranging from 0.41%-0.72% and 160.85-191.33cm, respectively. Thus, the study comes to the conclusion that broiler chickens can safely be fed maiwa and pearl millet along with other items as nutritional energy sources.

PERANCANGAN SISTEM INFORMASI ANALIS BREAK EVEN POINT DAN STOK PADA BUDIDAYA AYAM POTONG BERBASIS WEB

Although broiler chicken farming offers many benefits, there are also risks of losses, especially when production costs are not accurately recorded, leading to inaccurate per-unit pricing that can harm farmers. To assist farmers in accurately determining the Break Even Point (BEP) price for each chicken, a web-based cost and stock management information system for broiler farming has been developed. To provide a clear and sequential software lifecycle approach, this system was built using the waterfall method, which includes the stages of requirements analysis, design specifications, coding, testing, and maintenance. Each stage produces measurable outcomes before proceeding to the next. The development results indicate that the system successfully records the total production costs, including detailed costs for feed, medicine, operational expenses, and chicken stock. By using the formula BEP = total production cost/number of live chickens, the system achieves accurate pricing for broiler chickens. Based on these findings, future research is suggested to improve the user interface for greater appeal, optimize system accessibility on mobile devices, and integrate this system with other systems.

DIFFERENTIATED IN VITRO LYSOZYME ACTIVITY IN AVES AND MAMMALIA IN RESPONSE TO SEABUCKTHORN (HIPPOPHAE RHAMNOIDES) STIMULATION

Lysozyme, an intrinsic component of the immune system, is a naturally occurring enzyme with antimicrobial activity (Khorshidian et al., 2022), by hydrolyzing the muramyl dipeptide in the bacteria cell wall. Considered to be an endogenous antibiotic, it differs by species (Ferraboschi et al., 2021). Some of the medicinal plants were cited to inhibit the anti-lysozyme activity and biofilm formation by bacteria (Bukharin et al., 2003). The aim of this research was to evaluate the differences in the in vitro activity of lysozyme between the classes Aves and Mammalia when treated with a protein-carotenoid extract of Hypopphae rhamnoides compared to well-known immune modulating preparations (selenium or selenium and copper compounds). The investigations were carried out on serum samples from: a) commercial broiler chickens aged 34 days (n = 19) and b) 5-month-old Supercunirom breed male rabbits (n = 19). The agar gel radial immune diffusion method and the Micrococcus lysodeicticus test strain were used to define the in vitro lysozyme activity. The sera were mixed with serial dilutions (1:2, 1:4, etc.) of the tested compounds. The groups were compared by Student’s t test for statistical significance of the results. He increase in activity (%) versus control were calculated. Sea buckthorn extract significantly (t= 7.22, p &lt; 0.001) decreased the in vitro activity of lysozyme at both dilutions used (1:2, 1:4). The concentration of serum lysozyme was higher in rabbits than in chickens and its lytic activity was enhanced by selenium and copper combinations in chickens (183.69 ± 37.91%) and less in rabbits (128.45 ± 84.10%) in a dose dependent manner. At lower dilutions (3:4), the lysozyme activity remained below that of the control treated with saline. The protein-carotenoid extract of sea buckthorn acted inhibiting on lysozyme activity, proving the need for tailored extraction and treatment protocols depending on the bacteria and host species.

Long-Term Effects of Early Low-Phosphorous Nutritional Conditioning on Broiler Chicken Performance, Bone Mineralization, and Gut Health Under Adequate or Phosphorous-Deficient Diets

Phosphorous is essential for many metabolic functions and the constitution of bones. Poultry have limited ability to use phosphorous from diets, which is mainly excreted and causes environmental concern. For this reason, diets are commonly supplemented with inorganic phosphorus and phytases. It has been suggested that chickens can adapt to an early nutrient restriction by increasing its efficiency of utilization, an adaptation that has been defined as nutritional conditioning. The aim of this study was to investigate a strategy of phosphorous nutritional conditioning by feeding low phosphorous diets during the first week of life as a strategy to improve the efficiency of phosphorous utilization later in life. To test this, 600 male broiler chickens were fed either a standard (control group) or a phosphorous-deficient diet (conditioned group) during the first week of life. Later in life, the effect of conditioning was tested using standard or P-deficient diets during the finishing phase (21–43 d). Conditioning did not affect overall performance, despite finding evidence for reduced relative phosphorous excretion between days 19 to 21, increased duodenal gene expression for the phosphorous transporter SLC34A2 at day 30 (−6% and +17%, respectively), and tendencies for improved phosphorous digestibility (+7%) and tibia mineralization (+6%) at the end of the trial. It is concluded that phosphorous nutritional conditioning early in life can increase subsequent dietary phosphorous utilization and bone mineralization in poultry, although it may not be able to counteract severe phosphorous deficiencies. Further research is required to assess the extent to which phosphorous supplementation in post-conditioning diets may be reduced with this strategy without compromising performance.

Effect of Supplementation of Spirulina (Spirulina platensis) on Growth Performance of Broiler in Konkan Region, India

The experimental trial of six weeks was conducted on 200 broiler chicks. They were randomly distributed into five experimental treatment groups. Each treatment group was replicated into four with 10 birds per replication. The control (T1) group was fed standard ration and T2, T3, T4 and T5 group were provided same standard ration supplemented with 1.00 g, 2.00 g, 3.00 g and 4.00 g spirulina powder, respectively. The result of experimental trial showed that supplementation of spirulina powder was significantly highest live body weight in treatment T5 (1944.50 g/bird) as well as average live body weight gain (277.79 g/bird). It is concluded that, 4.00 g of spirulina powder significantly improved growth performance of broiler chicks than other treatments groups.

Comparison of Different Antibiotic Alternatives for Safe Broiler Production

The use of growth-promoting antibiotics in broiler feed, once widespread, is now recognized as risky due to antibiotic resistance and residue concerns in meat. To mitigate these risks, the goal of this study was to compare different alternative additives like organic acids, neem, enzymes, and probiotics for producing a safe broiler. A total of 360 Cobb-500-day-old broiler chicks were indiscriminately assigned into six treatment groups, i.e., Control (T1), Basal feed + Antibiotic (T2), Basal feed + Organic acid (T3), Basal feed + Enzyme (T4), Basal feed + Probiotic (T5), and Basal feed + Medicinal plant (T6) having four replications of 15 birds in each. During the experiment, significant differences (P &lt; 0.05) in body weight (BW), body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) among the experimental groups were observed only in the 5th week. At the end of the study, the highest BW, BWG, and FCR were found in organic acid, followed by the enzyme, antibiotic, probiotic, neem, and control group. There were no significant differences (P &gt; 0.05) in BW, BWG, and FI among the dietary groups during the 1st, 2nd, 3rd, and 4th weeks. No significant differences (P &gt; 0.05) in meat yield (drumstick meat, thigh meat, wing weight, and breast meat), bone development, and dressing parameters were observed among the dietary groups. Supplementation of different additives significantly (P &lt; 0.05) affects cholesterol and glutamic oxaloacetic transaminase content, whereas HDL, LDL, triglyceride, GPT, and creatinine were not affected among the groups. The neem and organic acid groups had the lowest cholesterol and glutamic oxaloacetic transaminase values, respectively, compared to the others. It can be concluded that supplementing organic acid, probiotics, enzymes, and neem enhanced the growth performance, carcass quality, and blood biochemical profiles of the broilers, potentially serving as antibiotic alternatives. Mainly, the organic acid gives the best results among all the antibiotic alternatives.

Using an enzyme preparation and vitamin C to increase the meat productivity of broiler chickens

Purpose: to study the effect of vitamin C and MEK Feedbest®VGPro when introduced into the compound feed of broiler chickens with excessive background of heavy metals on the indices of meat productivity, food and biological value, ecological safety of their meat.Materials and methods. The objects of the study were meat chickens of the ROSS-508 cross. At the age of one day, 4 groups of 100 birds each were formed from them in accordance with the principle of analog groups. In the composition of the used recipes of complete compound feed in all three age periods of growing, the main grain and protein ingredients were represented by locally produced feed: corn, wheat, peas and rapeseed meal. Growing of experimental broilers for meat was completed at the age of 42 days and their control slaughter was carried out, for which 5 birds were selected from each group. The concentration of salts of heavy metals was determined in the samples of feed and meat of the experimental birds.Results. The experiment substantiated the feasibility of combined introduction of MEC Feedbest®VGPro at a rate of 100 g/t of feed and vitamin C at a rate of 500 g/t of feed into diets with excessive content of heavy metal salts. Compared to the control analogues, broilers of the 3rd experimental group showed a reliable (p&lt;0,05) decrease in fat by 0,26 % and a simultaneous increase in dry matter, protein and the value of the protein-quality indicator in the pectoral muscle samples. Combined additions of the tested preparations contributed to a decrease in the concentration of zinc by 63,17 % (p&lt;0,05), cadmium by 61,11 % (p&lt;0,05) and lead by 62,34 % (p&lt;0,05) in poultry meat samples from the 3rd experimental group, compared to the control. Moreover, in the meat samples of broilers of the 3rd experimental group, the maximum permissible concentrations of none of these elements were exceeded.

Effect of Bacillus licheniformis on Growth, Bone Mineralization, and Intestinal Microbiota in Broilers Fed Cowpea Diets

This study investigates the effects of the Bacillus licheniformis (BL) ATCC 21424 strain, as a potential bacterial probiotic in broiler diets based on soybean meal (SBM) or cowpea seeds (CWP), on growth performance (GP), bone mineralization, and intestinal/fecal microbiota status (0 to 42 d age). A 2 × 2 factorial arrangement was employed in a completely randomized design, with four dietary treatments: SBM and CWP diets with or without BL supplementation (1.0 × 1011 CFU spores g−1 feed). A total of 480 one-day-old mixed-sex Ross 308 broiler chickens were randomly assigned to the treatments, with 6 pens of 20 chicks each. The results showed that broilers fed with CWP diets showed comparable body weight gain (BWG), feed intake (FI), and feed conversion rate to those fed the SBM diet (p &gt; 0.05). The inclusion of BL improved BWG during the grower and finisher periods (p = 0.01) and overall study (p &lt; 0.001), resulting in a numerical increase in FI (p = 0.054). In addition, BL in birds’ diets reduced abdominal fat (p = 0.032) and influenced cecum weight (p = 0.040). Additionally, BL improved tibia iron (Fe) and phosphorus (P) bone mineralization and reduced the calcium–phosphorus (Ca:P) ratio (p = 0.0001). Microbial analysis revealed that BL inclusion decreased Coliforms counts in the CWP diet (p = 0.073), reduced E. coli in the ileum (p ≤ 0.05), and lowered Clostridium spp. and Enterococcus spp. in the cecum broilers on SBM diets (p ≤ 0.05). The presence of Staphylococcus spp. in broiler feces was also reduced in both SBM and CWP groups (p &lt; 0.05). In conclusion, the addition of BL to broiler diets enhanced growth performance and bone mineralization and positively influenced gut and excreta bacterial populations in both SBM and CWP diets.

Dietary Zanthoxylum bungeanum leaf powder improves growth performance and antioxidant capacity via Nrf2/HO-1 signaling pathway in broilers.

This study focused on the effects of dietary Zanthoxylum bungeanum leaves (ZBL) powder on the growth performance and antioxidant capacity via the Nrf2/HO-1 signaling pathway in broilers. The experiment adopted a single-factor completely random design, and 440 healthy one-day-old AA broiler chicks were randomly divided into four groups: the control group (CON) was fed a corn-soybean meal-based diet, the CZ1 group was fed a basic diet with 1% ZBL powder, the CZ2 group fed a basic diet with 2% ZBL powder, and the CZ3 group fed a basic diet with 3% ZBL powder. The experiment was divided into the starter period (1-21 d) and the grower period (22-42 d). There were five replicates per group in the starter period, with 22 chickens per replicate. The same grouping as in the starter period was used in the grower period, with 20 chickens per replicate. The results showed that the addition of ZBL powder to the diet had no adverse effects on the growth performance and morphological structure of the intestine of broiler chickens in the CZ1 and CZ2 groups (P > 0.05). Compared with the control group, the diet with 1% and 2% ZBL powder significantly increased the antioxidant indicators such as CAT, T-AOC, and T-SOD in the serum and liver tissue of broiler chickens, it upregulated the related genes expression of nuclear factor erythroid derived-2/heme oxygenase-1 (Nrf2/HO-1) signaling pathway such as Nrf2, NQO1, HO-1, SOD1, and CAT in the jejunal mucosa and enhanced the expression of ZO-1 and OCLN genes in the jejunal mucosa (P < 0.05). In conclusion, dietary supplementation with 1% and 2% of ZBL powder into the daily diet can enhance the body's antioxidant capacity by elevating antioxidant levels in both serum and liver, upregulates the expression of genes associated with the Nrf2/HO-1 signaling pathway in the jejunal mucosa, and helps maintain the integrity of the intestinal mucosal barrier. The optimal addition level of ZBL powder in the diet was determined by quadratic regression analysis to be 1.36%-1.60% during days 1-21 and 1.14%-1.50% during days 22-42.

ANALYSING DETERMINANTS OF HOUSEHOLD BROILER CHICKEN MEAT PURCHASES AMIDST SOCIAL-MEDIA MISINFORMATION: A TOBIT STUDY

The Indian poultry sector significantly boosts GDP. It is grown at 8-10% annually, reaching $22.97 billion in 2022, expected to hit $41.94 billion (10.18% CAGR) from 2023 to 2028. Social media misinformation adversely affected the broiler sector, lowering prices and consumption. Using the Tobit Model, this study analysed Indian households' broiler chicken purchases during misinformation. Data on demographics, socioeconomics, and monthly consumption of chicken meat was collected from 503 respondents and analysed. On average, men favoured broiler chicken, while women preferred native chicken. The potential impact of social media misinformation on women's choices and the influence on households with senior citizens, which consumed significantly less quantity compared to their counterparts, remained intriguing. Unexpectedly, households with better incomes and more education purchased less broiler meat. Marital status, place of residence, cohabitation, and presence of children did not significantly affect the outcome. Muslim families purchased more broiler chicken meat, and larger households consumed more. Consumption frequency was important, with daily and alternate-day customers making larger purchases. Purchases of broiler meat were negatively impacted by the consumption of country chicken. Amidst social media misinformation, while a slight adverse impact on household broiler consumption may have occurred, it's notable that a significant portion of households (97.20%) continued to purchase broiler chicken meat, exhibiting the potential effectiveness of media-driven interventions in mitigating the impact of misinformation and reiterated the persistent favourability for broiler chicken as a dietary protein choice within the larger consumer demographic. The Indian poultry industry is vital for food security and economic growth, making it imperative to address social media-induced panic. Transparency, trust, and accurate information transmission are essential. In order to effectively handle market challenges, stakeholders need to take into account factors like demography and dietary preferences that impact consumer behaviour.

Effect of antioxidant and adsorbent on the digestibility and digestibility of nutrients in broiler diets while reducing the risk of aflatoxicosis

Purpose: determination of the adsorbent toxin and antioxidant vitamin C on the digestibility and assimilation of nutrients in the composition of compound feed for broiler chickens with a tolerant level of aflatoxin B1.Materials and methods. The objects of the study were broiler chickens of the KOBB-500 cross. When setting up the experiment, the duration of 42 days, 4 groups of 100 heads each were formed from day-old chickens according to the principle of analog groups. The experimental birds were fed complete compound feeds (CF) based on corn, sorghum and fodder beans. The samples of compound feeds have a high chemical composition and the presence of mycotoxins. Upper limits of permissible concentrations (ULC) for aflatoxin B1 were established in all three types of feed grain. Therefore, they were mixed with safe mycotoxin additives using dispensers in the feed shop of the poultry enterprise. In this way, tolerable levels (no more than 0,25 mg/kg of feed) of the content of this mycotoxin in the composition of the PK fed to the experimental birds were achieved. Against the background of the conducted scientific and production experiment with the use of chromium oxide in the composition of compound feed (as an inert indicator) on chickens (aged 35-42 days) of comparable groups (5 heads from each group), we conducted an exchange (physiological) experiment. Based on the results of chemical analysis of the fed compound feed and excrements in the droppings of the experimental birds, the level of digestibility and assimilation of nutrients in the diet was calculated.Results. During the experiment, the leadership of the combined introduction of the adsorbent toxfin in the amount of 1500 g/t and ingredient C in the amount of 500 g/t of feed into complete feeds for broiler chickens with a tolerant level of aflatoxin B1 was established. As a result, compared to the birds of the control group, the chickens of the 3rd experimental group had significantly (р&lt;0,05) higher coefficients of digestibility of dry matter by 3,66%, organic matter by 3,90 %, crude protein by 3,63 %, fiber by 3.06% and NFE by 3,19 %, respectively. In terms of the degree of nitrogen assimilation (60,45 %), the result (51.45 %) and phosphorus (49,67 %) from the generally accepted amount with feed, the best indicators were also obtained in broilers of the 3rd experimental group, which reliably (р&lt;0,05) outperformed their control indicators for these indicators by 3,74 %, 2,91 % and 2,45 %, respectively.
