Our attention was drawn to an important biological value of arginine. Arginine performs the role of building blocks of proteins and polypeptides, regulate key metabolic pathways that are necessary for maintenance, growth, reproduction, and immunity. Arginine is one of the most versatile amino acids in animal cells. It is required for the synthesis of several compounds, such as ornithine, polyamines (spermidine, spermine, and putrescine), proline, creatine, protein, nitric oxide, and citrulline, besides glutamate and agmatine in mammals. Arginine is also a powerful secretagogue, increasing the release of insulin, the growth hormone, and IGF-I in the blood stream. For birds this amino acid is indispensable. The basis of mixed fodders for quails lacks the arginine grain. So the introduction of its synthetic counterpart is a prerequisite for effective production of poultry meat. Experiments were carried out at an experimental base for problem research laboratory of feed additives at the Department animal feeding and feed technology named after P. D. Pshenychnuy of the National University of Life and Environmental Sciences of Ukraine. For this experiment, we used the breed Pharaoh. We investigated the impact of different levels of arginine in mix fodder on indicators of slaughter of youngsters quails of meat production . We found that feeding quails aged 1-35 days of feed containing 1. 66% arginine increases the quails weight before slaughter by 3%. The aim of this research is to establish the optimal level of arginine in the fodder for young quails by comparing their parameters of slaughter. The results of our investigation have practical value and can be used for work of poultry house.
Key words: quails, amino acids, arginine, mixed fodder, indexes of slaughter, the yield of edible parts.
