“…Arginine plays a crucial role in various metabolic, pathophysiological and immunological processes in poultry (Fernandes & Murakami, 2010;Fouad et al, 2012;Khajali & Wideman, 2010;Ibatullin et al, 2020). Due to the absence of the urea cycle, birds are unable to synthesize endogenous L-arginine and therefore this amino acid is indispensable (Tamir & Ratner, 1963).…”

Licensed under a Creative Commons Attribution 4.0 International LicenseThe article presents the results of the research on the effect of different levels and ratios of arginine and lysine in the compound feed of broiler chickens on their meat productivity. We conducted the research by the group method, on 600 heads of Cobb-500 crossbred broiler chickens, divided into six research groups according to the principle of analogs. During the experiment, chickens consumed the compound feed that differed only in the content and ratio between essential amino acids: arginine and lysine. We established the efficiency of increasing the arginine-lysine ratio in the compound feed of broiler chickens to 1.10 at the age of 1-10 days; 1.06 at the age of 11-22 days and 1.07 at the age of 23-42 days. That contributed to an increase in the pre-slaughter live weight by 0.68-0.88% (р <0.05), the carcass weight before evisceration -by 0.97-1.27% (р <0.05), the semi-eviscerated and eviscerated carcass weight -by 0.39-2.24%, the breast muscle weight -by 8.95-11.47% (p <0.01), and the leg muscle weightby 1.67-9.47% (p <0.05). The yield of the breast muscles increased by 1.64-2.18% (р <0.01), of the leg muscles -by 0.17-1.47% (р <0.05); the meatiness of the carcass, breast and legs increased, respectively, by 3.45% (р <0.05); 1.80 (р <0.05) and 1.64%; the yield of edible parts increased by 1.46-3.96% (р <0.05). Narrowing the arginine-lysine ratio, accordingly to 1.02; 0.97 and 0.98, led to a decrease in the yield of breast and leg muscles by 1.91 and 1.07%, respectively (р <0.05); the yield of internal fat increased by 0.40-1.10% (р <0.05); carcass meatiness decreased by 1.08-3.23% (р <0.01), breast meatiness -by 0.66-2.15% (р <0.05), leg meatiness -by 0.43-1.10% (р <0.01); the yield of edible parts decreased by 0.11 -0.33%.

It is established that the growth of young quails depends on the optimal glycine content in the feed. The article presents data on the use of compound feed with different levels of glycine in the feeding of young quails of meat productivity. The research was conducted in the vivarium of the Department of Animal Feeding and Feed Technology. PD Wheat on quail breed Pharaoh. 300 day-old quails were selected for the experiment and three groups were formed. The level of glycine in feed for experimental animals was regulated by the introduction into its composition of a synthetic preparation of this amino acid by weight dosing and stepwise mixing. It was found that the live weight of quails depended on the glycine content in their diet. Thus, from the age of 14 days, the quails of the second and third groups had a live weight higher by 1.2% and 1%, respectively, compared to the control. At 21 days of age, the live weight of quails of the second group, which was fed feed containing 1.50% glycine, was 0.9% higher than in the control group, and the third group, with the level of glycine 1.60% – 1% lower. When feeding quail feed with a content of 1.50% glycine, their live weight at 28 days of age was 1.5% (P<0.01) greater than the control, and the live weight of birds of the third group was 1.5% (P <0.01) less. At the age of 35 days, the quails of the second group had the largest live weight, which is 0.9% more than the birds of the control group. During the first week of life, quails of the second group had an average daily gain less than analogues from the control group by 1.9%; and a week later, this figure increased by 2.6% compared to control. The highest average daily gain for the entire period of the experiment was in poultry of the second group – 8.72 g, which is 0.9% higher than in the control. Thus, it was found that feeding quails compound feed with a glycine content of 1.50% contributes to an increase in their live weight by 0.94%, average daily gains – by 0.9%, and reducing feed costs per 1 kg of growth by 1.4%.

Currently, a growing industrial poultry sphere in many countries is quail farming. Quails have a complex of unique economic-productive advantages, as compared with other poultry, – high body temperature, intensive metabolism, small size, fast maturation, and high egg productivity. In the study, we examined the specifics of microscopic structure of morphometry of the spleen of the control and experimental birds as characteristics sensitive to the action of supplements. The proposed methods are intended for studying effects of protein-vitamin mineral supplements on poultry farming. Therefore, for 21 days, with the main diet, the quails were given mineral supplements produced by the Multilife trade mark (crude protein, amino acids (lysine, threonine, methionine, cysteine), calcium, available phosphorus, sodium, chlorine, vitamins (A, D3, E)), by the Missi trademark (protein, vitamins, minerals), and by the Standard Agro trademark (soybean press cake, vitamins А, D3, Е, В1, В2, В6, В12), multi-enzyme complex, salt, ground limestone, phosphate monocalcium, amino acids (lysine, threonine, methionine with cysteine). This is the first study of the ultrastructural organization of the spleen of Japanese quail (Coturnix japonica) fed with protein-vitamin mineral supplements. The tested supplements were beneficial for the productivity of the quails, as evidenced by increase in the body and spleen weight. Body weight of the quails increased by 5.8% in the group that was fed additionally with the Multilife supplement, and by 12.5% in the group that consumed the Missi supplement added to the fodder, and by 8.1% in the group that consumed the Standard Agro supplement with the diet. At the same time, the spleen weight increased by 7.2%, 16.0%, and 10.5%, respectively. However, the relative weight (0.1%) underwent no changes, which characterizes this parameter as permanent for age and species of animals. Analysis of the data of our morphological studies revealed that the splenic microscopic structure of the quails was characterized by presence of support-contractile apparatus (capsule and trabeculae) with the relative area of 4.6 ± 0.8% and single radial trabecula. The parenchyma was formed by white and red pulps without distinct boundaries. In the white pulp, there were designated lymphoid nodes with no light centers, and also periarterial lymphoid sheaths and ellipsoids. In the reticular stroma of the white pulp of the spleen, we found blood cells of various maturity, in particular, lymphocytes, which were clearly divided into large, average, and small; mononuclear and multinuclear macrophages, which contained hemosiderin and melanin, leukocytes, mostly eosinophilous. The ultrastructural organization of the spleen of the quails had the following peculiarities: nuclei of leukocytes contained large nuclei, endotheliocytes of the central artery of lymphoid follicle performed phagocyte function by accumulating autophagosomes in its cytoplasm. In the quails that had consumed the diet containing supplements, the macroscopic, microscopic, and ultramicroscopic structures underwent no changes. At the same time, there was seen a tendency towards increase in the relative area of white pulp and the support-contractile apparatus. The relative area of white pulp of the spleen increased by 0.5% in the group of quails that had received the diet with the Multilife supplement, by 1% in the group that had consumed the diet with the Missi supplement, and by 0.6% in the group that had consumed the diet with the Standard Agro supplement. The relative area of the red pulp in the spleen of the quails was observed to have the tendency towards decrease: by 0.4% in the group that received the Multilife supplement, by 1% in the group that consumed the Missi supplement, and by 0.5% in the group that consumed the Standard Agro supplement. The relative area of the support-contractile apparatus of the spleen increased by 0.4% in the group of quails that consumed the Multilife supplement, by 1% in the group that consumed the Missi supplement, and 0.5% in the group that consumed the Standard Agro supplement. Taking into account the data we obtained, we may conclude that our studies confirm the benefits of using modern protein-vitamin supplements in poultry farming for stimulation of growth and development. Especially valuable is the absence of negative effect on the morphofunctional parameters of the spleen, which we used as biomarkers.
