Abstract
<p>The productivity of young meat quails was estimated at use of feed with different levels of arginine. Experimental studies were conducted in course of Problem Research Laboratory of feed additives of National University of Life and Environmental Sciences of Ukraine. Pharaoh quails were used for scientific experiment that was carried out by method of analog groups. Arginine level contamination in the diets of experimental groups was regulated by the introduction of feed synthetic analogs of amino acid. Part of arginine in mixed fodder of poultry control group was 1.57 % in the fodder of quails of 2-nd, 3-rd, 4-th and 5-th research groups and that were 1.39, 1.48, 1.66, 1.75 % respectively. The feeding of the was done by group and feed was distributed twice – in morning and evening. Ii was proved that the feeding of quails by mix fodder with arginine content of 1.66% contributes to increment of the live weight by 2.6 % on average, daily gain - by 2.7 %, the weight before slaughter by 3 % and reduce the cost of feed per 1 kg of growth by 1.5 %. This could contribute to the further research of arginine-lysine optimal ratio in mixed fodder for quails and their impact on zootechnical indices.</p>
