“…Formulation of a compound feed with the content of amino acids corresponding to the "ideal protein" is the crucial condition for the most effective use of the genetic potential of modern crossbred broiler chickens characterized by fast growth rates. In addition, amino acid nutrition is the main factor in ensuring poultry health and product quality (Nahm, 2002;Kryvenok et al, 2017a, Kryvenok et al, 2017b.…”

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%.

“…Based on an in-depth study of the phenomena of imbalance, it has been established that even a small excess of amino acids in poultry diets can cause a sharp decrease in biosynthetic processes in their body (Zampiga et al, 2018). Topical issues are both the improvement of feed nutrition assessment systems and the development of recipes for the most effective feed, and new approaches to the normalization of amino acid nutrition of poultry, taking into account both quantitative and qualitative indicators (Kryvenok, 2017). The bird's need for essential amino acids depends on the level of protein in the diet and can vary widely.…”

The influence of different levels of arginine and lysine in compound feeds of replacement chickens on their growth, development and metabolism was studied. The effective ratio of arginine to lysine in the diets of replacement chickens was experimentally established, which, depending on the rearing period, was: 1.0:1 for 1-3 weeks, 1.1:1 for 4-8 weeks, 1.2:1 for 16 weeks and 1.2:1 for 17-18 weeks. It was found that the change in the ratio of arginine and lysine in poultry diets has a much higher degree of influence on their productivity, digestibility of feed nutrients, assimilation and efficiency of amino acids than changes in the levels of these amino acids. It was found that the ratio of arginine and lysine in the last period of rearing chickens (16-18 weeks) to a lesser extent affects the productivity of replacement young (R2=0.59) compared to the first (R2=0.96) and second periods of rearing (R2=0.65). The growth of replacement young during all periods of the experiment and the nature of the effect of changes in levels and ratios of these amino acids in feed depending on age and productivity, described by a mathematical model with nonlinear characteristics (polynomial trend line), which has a higher value of approximation (R2) linear dependence. The use of modern modeling methods and the proposed regression equations allow to predict the content of amino acids in feed for replacement young poultry in accordance with the program of their cultivation and amino acid composition of feed.

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%.
