Production and quality of meat from hair sheep grazing on Tanzania grass and supplemented with different protein levels

Objective: To evaluate the effect of a supplementary feeding (with different crude protein (CP) levels) in the yield and growth performance and meat characteristics of hair lambs grazed on Tanzania grass.
 Design/Methodology/Approach: A 120-d-1 experiment was conducted; it included four treatments and seven replications in a completely randomized design. Twenty-eight hair lambs (22.6 ± 1.6 kg LW) were allowed to graze on Tanzania grass (Panicum maximum) and were provided concentrate feeds (with 10, 12, 14, and 16% crude protein). The aim was to assess the effects of the latter food on growth, carcass characteristics, and meat quality.
 Results: Compared with the lambs fed with 10, 12, and 14% CP, the heaviest carcasses (P<0.05) were obtained from lambs fed with 16% CP. The percentage of crude protein and fat of the biceps femoris linearly increased (P<0.05) as the CP percentage increased in the concentrate feed. Meat color, water retention capacity, and cutting force were not impacted by the CP percentage of the concentrate feeds. Compared with the lambs fed with 10, 12, and 14%, the lowest palmitic acid percentage and the highest oleic acid percentage were found in the meat of lambs fed with 16% CP.
 Study Limitations/Implications: A high area was selected to avoid excessive rain.
 Findings/Conclusions: Compared with the lambs fed with 10, 12, and 14% CP, the lambs grazed on Tanzania grass and supplemented with 16% CP grew more, recorded a higher carcass yield, and their meat had a better unsaturated fatty acids ratio.

Oilseed flax and alfalfa as sources of nutrient elements in the Central region of non-chernozem zone of Russia

The article presents the results of research for the year 2022. The objects of the research were oilseed flax and alfalfa. Percentages of crude protein, fiber and ash elements were evaluated in the crops. The content of nutrient elements was estimated by infrared spectrometry. In flax the content of the studied elements in seeds was estimated, in alfalfa the content of nutrient elements in green mass after the second cutting was estimated. Among oilseed flax samples, the highest raw protein yield was provided by Raduga variety (3.40 c/ha), it also provided the highest ash element yield among flax samples (0.92 c/ha), and Nilin variety provided the highest fiber yield (2.24 c/ha). Among alfalfa samples, sample Taisia (152.15 c/ha and 154.44 c/ha, respectively) showed the highest values for raw protein and fiber collection, while sample Agnia (54.90 c/ha) was the leader in ash elements collection.

YIELD AND CHEMICAL QUALITY OF CHEPIL (Crotalaria longirostrata Hook. & Arn) FORAGE AT DIFFERENT SEEDING DENSITIES AND CUTTING FREQUENCY

Ruminant grazing in the tropics requires supplementation given the nutritional characteristics of pastures to cover protein needs. The objective of this research was to evaluate the yield and chemical quality of chepil (Crotalaria longirostrata Hook. & Arn) forage at different seeding densities and cutting frequencies to obtain the optimum harvest time. The experiment was set up in a completely randomized design with three replications. The treatments were planting densities T1: 200 000; T2: 100 000; and T3: 50 000 plants ha-1. The variables evaluated were: dry matter yield, morphological composition, growth rate, leaf:stem ratio, intercepted radiation, plant height, crude protein, neutral detergent fiber, acid detergent fiber, dry matter, and ash. For the 64-day cutting frequency, the three densities presented the highest yield with 3406, 3500, and 4200 kg MS ha-1, for 200 000, 100 000 and 50 000 plants ha-1, respectively (p < 0.05). PC decreased (p < 0.05) in T2 and T3 (23 %) in comparison to T1 (24 %). The planting density with the highest percentage of crude protein was 200 000 plants ha-1 with 24 %. The densities of 100 000 and 50 000 plants ha-1 presented a lower crude protein percentage, with 23 % (p < 0.05). It is concluded that the optimum cutting time is at 36 days of regrowth, when the chepil is planted at a density of 100 000 plants ha-1, and harvested at the frequency of 36 days of regrowth, since 95 % of intercepted radiation and better quality between yield and chemical characteristics, mainly crude protein, are obtained.

Effect of a Low-Protein Diet with Different Levels of Amino Acid Mixture in Laying Hens on their Performance and Some Qualitative Characteristics of Eggs

This study was conducted for the period from 1/1/2022 to 1/8/2022 (210 days), to study the effect of replacing the mixture of amino acids (methionine, lysine, and threonine) instead of the protein concentrate in the diets of laying hens that reduced crude protein by (1, 1.5, 2%) in some qualitative characteristics of eggs. In the study, (128) laying hens of the Lohmann Brown type were used, at the age of (21) weeks, preceded by two weeks of preparation for the herd. They were randomly distributed among 8 treatments, with 8 replications for each treatment, as each repetition includes (2) chickens (16 chickens/treatment). And the experimental treatments were as follows: T1 the control (standard diet), T2 (a treatment devoid of the protein concentrate), and the treatments T3, T4, and T5 (in which the percentage of crude protein was reduced by 1% and a mixture of amino acids consisting of methionine, lysine, and threonine was added by 1, 1.5, and 2%, respectively)., and treatments T6, T7, and T8 (in which the percentage of crude protein was reduced by 2% and a mixture of amino acids consisting of methionine, lysine, and threonine was added by 1, 1.5, and 2%, respectively). The results showed that there was a significant (P < 0.05) superiority for the treatments T1, T4, and T8 in yolk weight, yolk diameter, yolk relative weight, and yolk index at the middle of the experiment at the age of (21-32) weeks, while both were significantly superior (P < 0.05) From the coefficients T2, T9, T10 in the yolk weight, yolk height, yolk diameter, and the relative weight of the yolk in the last period of the experiment, The results showed a significant superiority (P < 0.05) for treatments T1, T8, and T10 when calculating the Albumin weight, Albumin height, Albumin diameter, and the relative weight of the egg, Treatments T2 and T3 were significantly (P<0.05) superior when measuring the weight of the eggshell, the relative weight of the eggshell, and the average thickness of the eggshell, compared with most of the experimental treatments. These results indicate that there is a qualitative improvement for some of the studied traits when adding the mixture of amino acids and reducing the percentage of total protein by 1.2% compared to the control group that does not contain amino acids.

Halquinol and nanoencapsulated essential oils: A comparative study on growth performance, intestinal morphology and meat quality in broiler chickens

Diets supplemented with halquinol and/or nanoencapsulated essential oils (N-EOs) have shown positive effects on the productive parameters of broiler chickens. However, there is limited comparative evidence between these two products. This study aimed to investigate and compare the efficacy of N-EOs blends with halquinol as dietary supplements for broiler chickens. A total of 500 male Cobb 500 broiler chickens were randomly assigned to five dietary groups. The control group received a conventional diet supplemented with halquinol (60%), while the experimental groups received supplementation with N-EOs blends derived from soursop (S), lemon (L), and eucalyptus (E) in different proportions: T1 (S:33.33%, L:33.33%, E:33.33%), T2 (S:50%, L:25%, E:25%), T3 (S:25%, L:50%, E:25%), and T4 (S:25%, L:25%, E:50%). The trial lasted for 42 days. The results showed that the T1 and T4 groups obtained the highest values (p &lt; 0.05) for average daily growth rate and breast yield. The feed conversion ratio was significantly lower in groups T1 and T4 (p &lt; 0.05). All N-EOs supplemented groups exhibited higher carcass yield (p &lt; 0.05). At day 42, the T1 group displayed increased villus height and villus height/crypt depth ratio in the duodenum (p &lt; 0.01), while all experimental groups showed increased villus width in the jejunum and ileum (p &lt; 0.05). Texture analysis revealed that N-EOs-treated groups had texture values similar to halquinol, except for the T1 group, which significantly increased hardness (p &lt; 0.05). Bromatological analysis showed that the T4 group significantly improved the percentage of crude protein, fat, and ash compared to the halquinol-supplemented group (p &lt; 0.05). Additionally, the T1 and T4 groups exhibited lower levels of lipid peroxidation (p &lt; 0.05). In conclusion, dietary supplementation with N-EOs holds promise as a potential alternative to halquinol, with the added advantage of improved oxidative stability.

Assessing the nutritional composition of sweet corn (zea mays l. var. saccharata) stover and kernel corn (zea mays l. var. indentata) stover for ruminant feed

Corn stover, which includes stalks, leaves, and husks left in the field after harvest, holds promise as a feed source for ruminant livestock due to its nutritional value. However, a lack of research on its nutritional composition has led to wasteful practices like open burning and disposal. Therefore, this study aims to determine and compare the nutritional value of corn stover between sweet and kernel corn. The samples of corn stover were collected at Universiti Sultan Zainal Abidin Farm. All samples were subjected to the cleaning, chopping, drying, and grinding processes before undergoing nutritional analysis using proximate analysis. The proximate analysis was measured based on the percentage of crude protein, ash, crude fibre, moisture, and fat. The results indicate that sweet corn stover exhibits the highest nutritional value (p&lt; 0.05) in terms of ash, crude protein, and fat, with percentages of 5.44%, 19.04%, and 3.86%, respectively, particularly in its leaves. Additionally, the stalks of sweet corn stover contain the highest percentages of moisture (4.89%) and crude fiber (27.05%). This study found that sweet corn stover is more suitable for ruminant feed because it contains the highest levels of essential nutrients like crude protein, fat, and ash.

PSII-14 Chemical Composition of Tropical Forage Fertilized with Different Sources of Nitrogen Fertilizers

Abstract Nitrogen fertilization can improve the chemical composition of tropical forages, as nitrogen is required at all stages of plant development. The aim of this study was to verify the chemical composition of Urochloa brizantha cv. marandu fertilized with different sources of nitrogen fertilizers from the following treatments: without nitrogen fertilization (CO), fertilization with urea (UR), fertilization with ammonium nitrate (NI) and fertilization with ammonium sulfate (SA). The study was carried out from December 2021 to April 2022, in the cerrado biome of Brazil at the FCAV/UNESP Forage Sector, Jaboticabal Campus, during the rearing phase of Nelore cattle, non-castrated males kept on pasture, managed in a continuous stocking system and variable load capacity. In treatments with fertilization, 150 kg of N· ha-1 were applied, divided into 3 applications. The design used was in randomized blocks (DBC). The evaluation of the chemical composition of the forage was carried out from collections every 28 days of samples of the fraction of the forage consumed by the animals through the hand-plucking method. The samples were dried at 55ºC for 72 hours and ground in a Willey mill, with a 1 mm mesh sieve. The chemical composition of the forage was estimated by spectroscopy in the near infrared light region, NIRS (Near Infrared Spectrometer), using a modular FT-NIR spectrometer. The data obtained were submitted to ANOVA and Tukey's test (P ≤ 0.05), using the statistical program R, version 3.4.4. Nitrogen fertilization significantly increased the organic matter content of the forage (P = 0.001). The organic matter content of the non-fertilized treatment was 91.97%, while the average of the fertilized treatments was 92.22%. The percentage of crude protein in the forage also showed a significant difference (P &amp;lt; 0.001) between the non-fertilized treatment, which had an average of 10.64%, and the fertilized treatments, which had an average of 17.75%. The neutral detergent fiber and acid detergent fiber components also differed from the application of nitrogen fertilizer (P &amp;lt; 0.001) but did not differ between the types of fertilizers. The neutral detergent fiber content was significantly different (P &amp;lt; 0.001) between the non-fertilized treatment (59.21%) and the fertilized treatments (54.30%). The observed data for acid detergent fiber were 31.46% for the treatment without the use of fertilizers and 30.24% for the treatments with the use of fertilizers. Non-fibrous carbohydrates and liguinin components were also analyzed, but showed no difference between treatments, P = 0.078 and P = 0.209, respectively. This study confirms that the chemical composition of Urochloa brizantha cv. Marandu can be significantly improved through the application of nitrogen fertilizers. However, our results showed no significant difference between the types of fertilizers tested.

A field experiment was carried out in three (03) areas viz: experimental field of Bangladesh Sericulture Research and Training Institute (BSRTI), Rajshahi, 05 farmers field of Bholahat, Chapainawabganj and 05 farmers of Paba, Rajshahi during 2020–2022. The objective of this research was to assess the effect of vegetables intercropping in mulberry garden on sericulture productivity and economy. Randomized completely block design (RCBD) with 3 replications and 7 treatments which includes, T0 = Sole mulberry (Control) T1 = Mulberry + Potato, T2 = Mulberry + Cabbage, T3 = Mulberry + Cauliflower, T4 = Mulberry + Red amaranth, T5 = Mulberry + Spinach and T6 = Mulberry + Data shak. The growth and yield parameters of mulberry viz average branch number per plant, total leaf number per plant, total branches height per plant (cm), nodes per meter per plant, length of longest shoot (cm), leaf present per branch, 10 leaves area (cm2), total leaf weight per plant (g), total shoots weight per plant (g) and total leaf yield/ha/crop (mt) were higher in T1 (10.89, 1223.35, 753.12, 23.03, 118.16, 20.58, 537.98, 833.35, 402.84 and 10.37) followed by other treatments except control (12.3, 1365.77, 768.82, 23.62, 122.5, 23, 572.92, 901.03, 414.76 and 10.82), respectively. Leaf quality viz moisture, total chlorophyll, crude protein, total sugar, reducing sugar and mineral percentage were significantly higher in T3 (75.7, 38.8, 20.85, 6.48, 4.1 and 12.71) respectively over the T6 (74.86, 38.05, 19.61, 5.59, 3.12 and 11.1). The silk cocoon attributes like weight of 15 larvae (g), single cocoon weight (g), shell weight (g), cocoon shell ratio, highest filament length (m), renditta and cocoon productivity/100 dfls (kg) were higher also in T3 (53.46, 32.41, 0.21, 19.85, 977.84, 11.1 and 70.66) as compared to T6 (51.48, 31.42, 0.18, 18.24, 966.04, 12.31 and 69.24), respectively. The growing of Cauliflower as an intercrop was given maximum B: C (2.31) due to expansion soil fertility, higher leaf yield (except control), leaf quality, cocoon yield and additional income paralleled with other intercrops (cabbage-2.09, red amaranth-2.05, spinach-1.67, potato-1.49, sole mulberry-1.34 and data shak-1.22).

Response of Ryegrass to Nitrogen Fertilizer under Two Irrigation Systems

The objective of this study was evaluation the effectiveness of the some irrigation systems, and determining the best nitrogen fertilizer level and its effect on some growth characteristics and quality of Italian ryegrass seeds. A field experiment was carried out in two locations, the first is the Khan Atshan pasture station in the Karbala, and the second is the Dikkah pasture station - Khanaqin affiliated to the Forestry and Desertification Control Department - Ministry of Agriculture during the fall season 2021-2022. The experiment was carried out according to a randomized complete block design, in split plots arrangement, with three replications. The main plots included two irrigation systems (solid set sprinkler irrigation and free flow irrigation), and the sub plots included the addition of four levels of nitrogen fertilizer in the form of urea (46% N): 0, 15, 30, and 45 kg N h-1, The results showed that the solid set sprinkler irrigation system was significantly superior to the free flow irrigation system in achieving the highest average of the total chlorophyll content in the leaves 17.69 % and 9.63%, crude protein in the cereal 20.54% and 23.60 % and the percentage of carbohydrates in the cereal 13% and 14% for both experimental location, while the free flow irrigation system was significantly superior in achieving the highest mean of the flag leaf area 4.32% and 5.08% and the dry weight of the plant 13.55% and 46.67% for both location. The results also showed that increasing the added nitrogen fertilizer up to the level of 45 kg h-1 led to a significant increase in each of the flag leaf area cm2 and the total chlorophyll content in the leaves mg g-1, percentage of crude protein in cereals, dry weight of plants, percentage of ash in cereals, and percentage of carbohydrates in cereals in two experiment location.

Yielding of aquaponics using probiotics to grow tomatoes with tilapia

Aquaponics is a cutting-edge technology where plants and fish are grown together in a close-loop re-circulating system. It is not feasible to use growth-promoting agents, such as pharmaceutical antibiotics, with this biological and ecologically friendly technology to prevent or treat fish diseases. Examination of different growth booster substances became necessary because of this, and probiotics are one potential solution. The purpose of this experiment was to figure out the effect of gut probiotics, water probiotics and biofloc inputs in aquaponics to grow tilapia and tomato. Tilapia was fed with 29.40% protein containing feed with the supplement of gut probiotics (AQ-GT), water additive probiotic (AQ-WT), combination of probiotics-molasses-yeast (AQ-BF) and without any probiotic supplement (AQ) as control in media-based aquaponics. The investigation was incorporated for 75 days with triplicates of each treatment. Water quality, tilapia and tomato plant were sampled at 15-days interval. Moreover, matured tomatoes were harvested regularly. The findings showed that the treatments differed significantly in terms of electric conductivity, dissolved solids, calcium, sodium, potassium, magnesium, phosphorus, boron, copper, ammonia, nitrite, and nitrate concentration in tank water. The highest tomato flower was recorded in control (P < 0.01). On the other hand, the highest tomato and tilapia production were in AQ-BF (P < 0.01). The research findings revealed that biofloc technology (AQ-BF) significantly lower the feed conversion ratio and enhance the specific growth rate of tilapia than the other treatments. Moisture, crude protein, crude lipid, crude fiber, ash, and nitrogen free extract percentage in tilapia varied significantly among the treatments. Contrarily, statistical similarity among the treatments exists in terms of moisture, lipid, and ash content of tomato. The results indicate that, combination of biofloc technology with aquaponics is more viable for higher fish and vegetable production with favorable water quality than the other ways of probiotic inclusion in aquaponics.

Fatty Acids and Mineral Content in Milk of Locally Reared Ruminant in Sokoto

The nutritional content of milk is determined by its protein, free fatty acids, and essential mineral contents which are indicators of high- quality dairy. This work aimed to evaluate some nutritional indices of milk obtained from locally reared Sokoto Red goats, Yankasa sheep, and Red Fulani cows. Milk samples were collected from each group of five breastfeeding goats, sheep, and cows. Crude protein and percent ash contents were determined using the Kjeldahl method while free fatty acid and mineral contents were determined using Gas Chromatography (GC) and Atomic Absorption Spectroscopy (AAS), respectively. The results obtained show that the percent crude proteins of cows, sheep, and goats were 7.00 ± 0.10, 9.60 ± 0.10, and 25.50 ± 0.10 %, respectively. The percent abundance of free fatty acids show that saturated fatty acids (SFA) were 54.70, 46.19, and 32.28 %, monounsaturated fatty acids (MFA) were 54.96, 47.76, and 35.94 %, while polyunsaturated fatty acids (PFA) were 1.71, 6.04, and 2.99 %, respectively for cow, goat, and sheep. The content of zinc, potassium, and magnesium in the samples were 24.30, 35.50, and 15.70 mg/L, and 11.20, 61.30, and 23.20 mg/L; and 85.20, 97.3, and 86.30 mg/L, respectively for cow, goat, and sheep milk. Results also showed that there is significant difference (p &lt; 0.05), between goat's milk which had high percent crude protein, zinc, magnesium, and potassium when compared with sheep and cow milk. Interestingly, sheep milk contained the important essential fatty acids arachidonic acid and nervonic acid in cow's milk. Quantitatively, goat and sheep milk MFA and PFA contents are superior to that in cow milk. While goat milk is rich in zinc, potassium, and magnesium, and significant presence of arachidonic acid in sheep milk, no significant difference was observed in the tested constituents of goat and sheep milk.

The effect of diet density on allometry in pullet growth and early egg production

Understanding the effect of nutrition on pullet growth curves and body composition may help to design new feeding strategies that influence body composition and (long-term) laying performance. Therefore, this study examined the effect of nutrient density (low, medium or high metabolizable energy and essential amino acids), fed in the rearing phase until 17 wk of age, on Hy-Line white W80 pullet growth, body composition development and egg production performance until wk 35. Data were subjected to mixed model analyses. To determine a multiphasic allometric relationship between body components, an overall growth curve was established and inflection points were determined. The linear higher BW at the end of the rearing phase, due to increased diet density, was maintained during the peak production phase until wk 35. Egg production parameters were not affected by rearing diet density. Breast and body crude protein percentages were not influenced by dietary treatments, whereas body crude fat and abdominal fat pad percentages were linearly increased with diet density from early age onward. Body crude protein was initially deposited at the same rate as body dry matter. In a second phase of growth from wk 12 onward, crude protein deposition was lower than body dry matter deposition, but was not influenced by rearing diet. Body crude fat, on the other hand, initially grew at a lower rate than body dry matter, but increased in deposition rate during a second phase of growth starting at wk 2 to 5. Pullets fed the high density diet showed higher deposition of crude fat vs. dry matter as compared to pullets fed the medium density diets in the first phase until wk 2, but exhibited lower crude fat deposition in the second phase until wk 8. These results indicate that until approximately wk 12, crude protein deposition was mainly driving growth and was not influenced by diet density. From wk 5 to 6 onward, crude fat deposition relative to protein deposition increased and this was influenced by diet density from an early age.

Compositional Analysis of Four Varieties of Rice-Chevally, Njavara, D1 and Bhadra

Background: Rice is the most important and extensively grown food crop in the world in terms of food, area and production. It is a staple food which serves for nearly half of the world’s seven billion people (IRRI, 2013). Rice constitutes high percentage of carbs with substantial amount of proteins, fat, fibre, mineral and vitamins. Methods: Composition and nutritional content of rice varies with varieties and especially processing method. The objective of the present investigation titled “Compositional Analysis of Four Varieties of Rice-Cheruvally, Njavara, D1 and Bhadra” was to compare the proximate composition and total amylose-amylopectin content of rice cultivars selected. Total Amylose content, amylopectin content and amylose-amylopectin ratio was estimated spectrophotometrically at 620 nm. Among the proximate composition analysis, percentage of carbohydrate, crude protein, ash, moisture and fat were determined using AOAC standard method. Result: In the present investigation the results of the proximate composition and the amylose content of all the four rice varieties indicated significant difference in all the parameters assessed. It is understood that the rice samples selected for the study belongs to high amylose variety with amylose-amylopectin ratio falling between 0.35-0.45. In summary, the study on the proximate composition and amylose content of rice cultivars has revealed some vital information and these generated results will find their way in determining their suitability in food and other relevant industries.

Influence of Ageing Time and Method on Beef Quality and Safety.

The effectiveness of dry ageing with regard to retaining meat quality is still subject to debate. At 4 d post mortem, samples of boneless strip loins were excised from young Charolais carcasses and then stored for a further 26 d in a cooler, either vacuum-packaged (VP) or dried-aged (DA). Loin samples were also dissected 7 d post mortem as a control treatment (CT). Chemical, instrumental and microbiological data (n = 18) were determined in longissimus dorsi and underwent ANOVA to estimate the differences in the ageing fixed factor split into two orthogonal contrasts: control vs. aged and VP vs. DA. Ageing loss (both surface dehydration and water purge) was greater in DA compared to VP samples, resulting in the lowest moisture content and highest crude protein and fat percentage in DA loins. The ageing method did not affect meat surface colour, except for redness, which had the lowest value in DA samples. Meat tenderness improved a similar amount following both VP and DA ageing treatments. Compared to the control, prolonged ageing raised both the peroxide value and the total microbial count, especially in DA samples, though both remained within the recommended limits. In summation, both ageing methods improved beef meat tenderisation, preserving its shelf life.

Nilai Nutrisi dan Rendemen Ekstrak Metanol Pelet Katuk Depolarisasi sebagai Parameter Standar Mutu Produksi

Standardization of the quality of the depolarized katuk pellet production process as a feed additive is very important to maintain product quality. The production process requires dry katuk leaves (DKK) as raw materials which are then processed into depolarized katuk leaves (DKD), and continues in the pelleting process to become depolarized katuk pellets (PKD). Quality standard can be done by measuring the parameters of nutritional value and also the yield of methanol extract. Nutritional values were obtained from the results of proximate analysis, namely the percentage of dry matter, ash content, crude protein, crude fiber, crude fat, beta-N, calcium, phosphorus, and gross energy (Cal/g). Mean while, the yield of methanol extract was obtained by maceration using methanol solvent. This study aims to evaluate the nutritional value and yield of crude methanol extract of katuk leaves (DKK, DKD, PKD) which can be used as a quality assurance standard for the depolarized katuk pellet production process. In general, the nutritional value of DKD and PKD had the same value as that of DKK, except for calcium which was quite high (P&lt;0.05) in DKD and PKD, and the percentage of crude fiber was lower (P&lt;0.05) in PKD compared to DKK and DKD. The percentage of crude fat in pellets (PKD) was higher (P&lt;0.05) when compared to DKK and DKD. The yield of methanol extract was very high (P&lt;0.05) in DKK, compared to DKD and PKD. The nutritional parameters and the yield of the katuk leaf extract can be used as quality assurance standards for the depolarized katuk pellet production process.&#x0D; &#x0D; Keywords: depolarization, katuk, methanol, nutrition, pellet

Optimization of Water Use Efficiency of Hydroponic Maize Fodder Production System under Different Microclimatic Conditions

Aims: Hydroponic method of producing fodder is an advanced technique which helps to achieve very high-water use efficiency (WUE). The main objective of the study was to optimize WUE by controlling the system and reducing the stress on the crops to give higher yield.&#x0D; Study Design: The experiment employed a statistical design known as Completely Randomized Design Place and duration of the study: The experiment was carried out in the Precision Farming Development Centre (PFDC) building, Kelappaji College of Agricultural Engineering and Technology (KCAET), Tavanur during May and June 2021.&#x0D; Methodology: Three different water application methods namely, mist (I1), micro sprinkler (I2), fogger (I3) was selected. Artificial light source of LED red (L1), LED blue (L2), LED red + blue (L3) and sunlight (L4) were considered for the study. Statistical analysis was conducted to understand the significance of different treatments used in the experiment in optimizing yield and WUE of the system.&#x0D; Results: Highest yield was observed in treatment involving fogger irrigation and LED red + blue (2.11 kg/tray) with highest WUE (515.43 kg/m3) compared to other treatments. Seed to fodder ratio obtained was 1:6. Chemical analysis showed higher percentage of crude protein (13.56%) and crude fibre (12.59%) in this treatment. Higher growth of green fodder under artificial light source can be attributed to the continuous supply of energy compared to highly varying sunlight and also the uniform distribution of water by fogger irrigation which maintained favourable condition for fodder growth.&#x0D; Conclusion: Results clearly indicated that growing green fodder with artificial light source (LED red + blue) and water supply with fogger can be recommended to farmers for achieving better growth of green fodder for domestic animals.

Effect of Dietary Supplementation of L-Valine on Growth, Immunocompetence Traits, Carcass Quality and Meat Composition of Turkey Poults

Background: Valine is an important amino acid and its deficiency may result in reduced growth and immunity. However, studies in turkeys are limited. Hence a study was conducted to assess the effect of supplemental L-valine (L-val) on growth performance, immunocompetence traits, carcass quality and meat composition of turkey poults. Methods: Day old turkey poults (n= 96) were distributed into four dietary treatment groups:T1-basal diet, T2-T1+0.04% L-val, T3- T1+0.08% L-val , T4- T1+0.12% L-val, having three replicates of 8 birds each. Result: No significance difference observed in average weekly body weight (BW), body weight gain (BWG) and feed conversion ratio (FCR) of birds throughout experimental period except at 7th week where T2 and T3 poults had a significantly higher (P less than 0.05) BW, BWG and significantly better (P less than 0.05) FCR. HA titre was significantly higher (P less than 0.05) in T3. Per cent breast weight was significantly higher (P less than 0.05) in T3. Percent crude protein level in breast muscle of turkey poults was significantly higher (P less than 0.05) in T3. Thus, supplementation of L-val @ 0.08% in turkey poults resulted in significantly better humoral immune response, higher percent breast yield and higher percent crude protein in breast meat.

Nutritional values of wild edible freshwater macrophytes.

The social acceptability of wild freshwater macrophytes as locally consumed vegetables is widespread. Freshwater macrophytes have several uses; for example, they can be used as food for humans. This study determined the proximate composition and mineral content of three freshwater macrophyte species, i.e., Eichhornia crassipes, Limnocharis flava, and Neptunia oleracea. Young shoots of E. crassipes, L. flava, and N. oleracea were collected from shallow channels of Puchong (3°00'11.89″N, 101°42'43.12″E), Ladang 10, Universiti Putra Malaysia (2°58'44.41″N, 101°42'44.45″E), and Kampung Alur Selibong, Langgar (06°5'50.9″N, 100°26'49.8″E), Kedah, Peninsular Malaysia. The nutritional values of these macrophytes were analysed by using a standard protocol from the Association of Official Analytical Chemists. Eight replicates of E. crassipes and L. flava and four replicates of N. oleracea were used for the subsequent analyses. In the proximate analysis, N. oleracea possessed the highest percentage of crude protein (29.61%) and energy content (4,269.65 cal g-1), whereas L. flava had the highest percentage of crude fat (5.75%) and ash (18.31%). The proximate composition trend for each species was different; specifically, all of the species possessed more carbohydrates and fewer crude lipids. All of the species demonstrated a similar mineral trend, with high nitrogen and potassium and lower copper contents. Nitrogen and potassium levels ranged from 12,380-40,380 mg kg-1 and from 11,212-33,276 mg kg-1, respectively, and copper levels ranged from 16-27 mg kg-1. The results showed that all three plant species, i.e., E. crassipes, N. oleracea, and L. flava are plant-based sources of macro- and micronutrient beneficial supplements for human consumption.

Utilization of Date Pulp and Pit Powder to make Decaf Coffee to Improve Cognitive Health

The health-conscious consumers are interested in replacing health-deteriorating drinks with functional beverages in current epochs. There is no higher truth that coffee consumption reduces risk of type II diabetes, Alzheimer, and other brain anomalies but it is also the fact that CGA (chlorogenic acid) and caffeine in coffee may pose risk of cardiovascular diseases and unhealthy mood fluctuations. Various health concerns of coffee consumption urge the need to produce a caffeine-free healthy alternative to coffee, which should also acquire the taste attributes of coffee. The development of instant coffee powder using date seeds and pomace powder for improved cognitive function can break new grounds in the market. The goal of the current study was to investigate the compositional profile of coffee prepared from date pomace and date seed powder. Date seeds were roasted at 200 °C for 20 min and a blend was made in combination with date pomace, milk powder and coconut as flavor enhancer. Proximate analysis of coffee powder such as moisture, ash, crude fat, crude protein, crude fiber and NFE percentages was determined. The results showed that prepared coffee powders contained significant fiber, low fat, less protein and a nearly equal percentage of moisture and ash as compared to Coffea arabica powder (control), with nearly zero caffeine content. Preliminary tests such as color, acidity, calories, total polyphenols, DPPH test, and FRAP assay were carried out because the study attempted to replace Arabica coffee beans with date beans. Phytochemical screening of coffee powders revealed that total phenolic content was highest for CB4 (20.90 ± 0.46 mg/g) which contained maximum date seed powder (35 %). Similarly, DPPH and FRAP assay were also found maximum for CB4 which were 81.11 ± 0.32 % and 23.17 ± 0.44 % respectively. Acidity and caffeine of prepared coffee powders were lower than control. It is hypothesized that decaf coffee may substitute caffeinated coffee for neurological health.

Valorisation of aquaculture sludge into microbial protein using bioreactor with an optimised nutrients

The present study was conducted to optimise the nutrients used for producing high nutritional biofloc in bioreactor utilising aquaculture waste. Full Factorial design (23) of independent variables such as sludge quantity (20 and 30 gL−1), carbon nitrogen ratio (15:1 and 20:1) and bioflocculant (cationic starch) doses (30 and 60 ppm) were used for optimisation. The percentage of crude protein and crude lipid in biofloc was shown to be significantly influenced by the interaction between carbon nitrogen ratio and bioflocculant dose (BC) as well as the interaction between sludge quantity, carbon nitrogen ratio, and bioflocculant dose (ABC) (p < 0.05). The floc volume of biofloc was shown to be significantly influenced by the interaction between carbon nitrogen ratio and bioflocculant dose (BC) (p < 0.05). The optimised parameters were 30 gL−1 of sludge, a carbon nitrogen ratio of 20:1, and 30 ppm of cationic starch, which resulted in a maximum CP of 27.09%, a maximum CL of 4.36%, and a maximum floc volume of 132 mL L−1. Principal component analysis (PCA) resulted in a 2 principal components (PC 1, nutritional factors which decides the nutritional composition of biofloc and PC 2, nitrification factors which are needed for biofloc formation) that explained 85% of total data variation. This study found the production of nutritive biofloc in a bioreactor using aquaculture waste with optimised nutrients.
