This study investigates the effect of different chromium picolinate levels as food supplementation and sex on Japanese quail meat characteristics. Ninety Japanese quail chicks with one day of age were reared in 340C temperature and continuously feed and water providing at the Faculty of Agriculture , University of Diyala animals’ field, vitamins were provided with water and temperature were monitored continuously. Birds were allocated for three treatments with convergent of weight average when reached the age of 14 days, each treatment contain three replicates and ten birds for each replicate, each replicate birds were rearing in cage with 50×50×50cm for four weeks (until 42 day of age), all treatments birds were provide with free same ration and chromium was added to the treatments ration as follows: control treatment: without chromium, treatment one (T1) adding 250μg (0.25mlg) chromium picolinate/kg ration, treatment two (T2) adding 500μg (0.5mlg) chromium picolinate/kg ration. After the period of the experiment finished, six birds were selected randomly from each treatment (three from each sex) and weighted then slaughtered, many measurements were taken from meat and carcasses, including hot and cold carcass weight, dressing percentage, carcass cuts weight, breast and leg cooking loss, thawing loss and meat chemical composition. Statistical analyses show that no clear effect of supplementation on these measurements and no real benefits from adding it with quail ration in this ratio and this experiment conditions and traits. It might be concluded that the chromium presented normally in ration and water was adequate to normal quail requirement and chromium supplementation may not be essential. Higher chromium ratio should be tested.

AbstractCommon carp (Cyprinus carpio L.) is a dominant fish species in aquaculture, and as it is a stomachless species, absorption and digestion of nutrients take place in the intestine. The aim of the study was to evaluate the effects of a prebiotic on the content of selected minerals found in the meat, gills, and skeleton of common carp. The research applied trans-galactooligosaccharide (GOS) prebiotic produced by enzymatic transgalactosylation of milk lactose by whole cells of Bifidobacterium bifidum. The following diets have been applied: control diet without feed additives (C), diet 2 (B1) with 1% of GOS, and diet 3 (B2) with 2% of GOS. In the freeze-dried samples, concentrations of the analyzed metals were determined using atomic absorption spectroscopy (AAS). The content of phosphorus was determined using colorimetric method. The analyses confirmed that the highest level of Mg was detected in the skeleton of fish fed with 1% GOS (2.51 g kg−1) and was significantly higher compared the control treatment (2.11 g kg−1) (P < 0.05). Zn content in fish meat fed with 1% GOS (35.41 mg kg−1) was significantly higher (P < 0.05) than in the control group (24.59 mg kg−1). The tissue that accumulated the greatest amount of Zn was the gills. GOS had a positive effect on Fe accumulation in the meat, gills, and skeleton. It has been concluded that supplementation of feed with 2% GOS significantly influenced the positive correlations between Mg and P in the meat and skeleton, Fe–Ca correlation in gills, and Fe–Zn correlation in the skeleton.

Abstract The response to probiotics and enzymes is often documented in research facilities with a high degree of control and via pigs with no insults to health or feed intake. However, in commercial conditions, the response to feed additives promoting advanced gut health and improved digestion must be consistent and defined over a wide range of health statuses, stocking densities, feed intakes, environments, and diet formulations. The objective of this experiment was to determine if a combined feed protease and probiotic system (Syncra® SWI 201, DuPont, Wilmington, DE) would improve growth performance and mortality under commercial conditions. A total of 127,092 pigs (6.0 ± 0.1 kg; PIC 337 sired, Hendersonville, TN) from a sow farm producing porcine reproductive and respiratory virus and rotavirus positive weaned pigs were placed in 53 2,400-head commercial wean-to-finish barns that were alternated to 1 of 2 treatments (a control treatment without Syncra® SWI (SSWI) or with SSWI included at 72.6 g/ton of finished feed from 22.7 kg of BW to harvest) in a rolling allotment over a 12-month period. Pigs were on the experiment for an average of 162 ± 1.0 days (until harvest). Throughout the 12-month experimental period, diets (outside of the SSWI inclusion) could change in order to maximize return over feed costs. Data were analyzed using Proc MIXED (SAS 9.4; Cary, NC) with treatment as the main effect and barn as the experimental unit. Compared to the control, adding SSWI improved mortality by 1.9% and percent grade 1 marketed pigs by 2.2% (P ≤ 0.025). Compared to the control, SSWI did not improve ADG (control = 0.75 vs. SSWI = 0.78 kg) or gain:feed (control = 0.401 vs. SSWI = 0.396). In conclusion, the inclusion of the SSWI combined feed protease and probiotic system can improve mortality and grade 1 marketed pigs, but not growth performance under commercial conditions.

The goal of the present study was to evaluatecharacteristics of the carcass and meat of steers and heifers, finished in feedlots and fed different high-grain diets. Forty-five bovines were used: 21 heifers, with an initial age of 32 months and initial weight of 359.9 kg, and 24 steers, with an initial age of 20 months and initial weight of 337.6 kg, from a Charolais × Nelore crossbreed. The animals were divided among the treatments, which were defined by the energy source used in the diet: rice, white oats, or corn; seven heifers and eight steers were used per diet treatment. The animals remained confined until reaching an estimated warm carcass weight of 220 kg. The experimental design was completely randomized, with a 3 × 2 factorial arrangement. Weights at slaughter were higher for animals fed white oats (449.3 kg) or corn (430.4 kg) than for animals fed rice (401.8 kg). Higher carcass yields were found in corn-fed animals. Animals that received rice had lower coverfat thickness. The yields of the rib and hind-quarter commercial cuts were higher for cattle that received white oats or corn. Animals that received corn diets had greater arm circumference than animals that received white oatsand both were larger than animals that were fed rice. The tenderness (5.15 points) and palatability (5.46 points) of rice-fed animals werelower than those of animals fed white oats (5.73 and 6.40 points, respectively) or corn (6.04 and 6.45 points, respectively). Slaughter weights were similar between categories - 424.1 kg and 430.2 kg for steers and heifers, respectively. Steers had higher fore-quarter yield (38.0% vs.37.4%), whereas heifers had a greater carcass length (126.0 cm vs. 123.1 cm). The finishing of cattle with corn- or white oat-based high grain-diets yielded heavier carcasses, with adequate deposition of fat, andbetter performance of principal carcass cuts. Feeding with rice in high-grain diets produced leaner meats, but reduced carcass weight, with greater losses upon cooling and less tender meat. The production of confined heifers or steers ensures similar meat products.

Abstract In the context of the implementation of environmental, resource-saving systems of agriculture, research in the system of biogeocenosis is very relevant: soil – plant-feed-animal-livestock products. Peatlands and developed peat soils are a kind of environment for human activity in this system. As a result of many years of research, it was found that perennial grasses grown on peat soils have differences in chemical composition compared to plants grown on mineral soils. They contain more organic matter and raw protein. However, their digestibility of nutrients is lower than in herbs grown on mineral soils. Therefore, for a full-fledged balanced feeding of cows, the realization of the genetic potential of animal productivity, and the preservation of their health, scientifically-based diets are necessary, developed on the basis of bulky feeds obtained from peat and developed soils, with the introduction of appropriate feed additives in them.

The materials of the article present data on research on the chemical, mineral-vitamin composition and nutritional value of a new feed additive from citrus pomace. The article presents the results of research on the technological line of granulation of citrus waste, established the optimal composition for granulation of citrus feed additives: sunflower meal - 20%, molasses - 5% and 75% of citrus fruits.Their chemical composition was studied, the gross content of proteins, fats, assimilated carbohydrates, including simple sugars, was determined, and the efficiency of use in the diets of farm animals was determined. The positive influence of citrus waste granulation technology has been established, which allows to obtain high-quality granules. Chemical analysis of citrus granules showed that 100 g contains: protein - 6.15 g, fat - 0.99 g, carbohydrates - 21.8 g, of which simple sugars 14 g, the energy value of this feed additive - Kcal (kJ) - 120.7 (505.7).The possibility of preparation of feed additives in the form of granules is revealed, which allows to avoid selfsorting of components and overdose of microelements and to improve the consumption of feed ingredients. The ability to prepare feed additives in the form of granules avoids self-sorting of components and overdose of micronutrients and improve the consumption of feed ingredients. The results of zootechnical researches, structure and nutritional value of average daily rations with use of citrus pomace are resulted.It was found that the introduction into the diet of dairy cows feed additives from citrus pomace during stable lactation increases the average daily expectations by 1.8 kg or 15.5%, feed costs for milk production containing 4 fat were 0.97-0, 98 feed units. When using a feed additive from citrus pomace, the nutritional value of the diet is improved due to the ratio of sugar - protein (0.62: 1 vs. 0.8: 1.2).

AbstractUse of antibiotics as feed additives has been reduced to avoid the hazard of drug residues, and consequently, the search for alternative natural additives has developed. Thus, the aim was to evaluate the influence of royal jelly (RJ) supplementation on milk composition, blood biochemical and antioxidant parameters of lactating ewes. Thirty-six Ossimi ewes were divided randomly into two groups (18 animals each). For a period of 4 weeks, the control group (CON) was fed a basal diet only, while the other group was fed the basal diet and supplemented with a single bolus of RJ (1000 mg/head). The RJ-supplemented ewes produced significantly higher milk protein, fat and total solids than the CON group. The RJ group had a significantly higher red blood cell count, haemoglobin content, haematocrit value and total leucocyte counts, but lower neutrophil to lymphocyte ratio when compared with the control treatment. The RJ group showed significantly higher concentrations of total antioxidant capacity, superoxide dismutase activity and glutathione in the serum compared with the control treatment. In conclusion, RJ supplements can improve the nutritive value of milk fat and the serum antioxidant activities in lactating ewes.

Abstract The aim of this study was to investigate the effects of a non-animal protein source in nursery diets on performance and carcass characteristics of wean to finish pigs. A total of 432 piglets with initial BW 6.31 ± 0.13 kg were blocked by BW and randomly assigned to 1 of 6 treatments. Treatments included PC1AP1: animal protein, nursery nutrient specifications without additives; PC2AP2: animal protein, growernutrientspecification without additives; NC1NP1: Non-animal protein, nursery specification without additives; NC2NP2: Non-animal protein, grower specification without additives; NC1 NP1 + FA[(Feed Additives)]: NC1 NP1 with additives; NC2 NP2 + FA: NC2 NP2 with additives. Feed Additives [Enzymes (Xylanase, β-Glucanase, Invertaseused), Oregano Essential Oil] were used in Treatments NP1 +FA and NP2 +FA. A linear model was used via the GLM procedure of SAS 9.4, with treatment as fixed effect and block as random effect. Pigs fed on the non-animal protein source and supplemented with feed additives had similar ADF, ADG, and G:F at finishing compared with treatment group on animal protein source (P > 0.05). No treatment differences (P > 0.05) for digesta, liver and serum based on a principal component AA analysis. (P>o.o5)[H2] No positive carry-over effects (P > 0.05) were found for performance except that pigs fed onthe animal protein source had greaterhad greater hot carcass weight (P < 0.05) than the non-animal protein group. In conclusion, wean pigs fed either animal or non-animal protein source at nursery had similar performance at finishing stage and similar carcass characteristics even though pigs on animal protein source had greater hot carcass weight relative to those on plant protein.
