Abstract
The experimental results of betaine-aldehyde additive use in young quail diets rations have been provided. To conduct the experiment, two groups of Phoenix quails at the age of 10 days fed with complete compound feed were formed. Poultry of the second group received betaine-aldehyde additionally with drinking water (Sumus LLC, Kazan). It has been established that in the second group receiving the experimental supplement, live weight and average daily gains were significantly greater in males than in control groups by 2.6 % (P≤000.1) and 7.9 % in females, by 4.5 % (P≤0.01) and 12.7 % (P≤0.001), respectively. In the second group of quails, the slaughter weight increased by 7.8 %, the mass of the ungutted carcass by 8.8 %, the half-gutted and the gutted carcass ‒ by 8.7 %, the yield of edible parts ‒ by 11.3 % and muscles by 13.5 % (P≤0.01), as well as the relative and absolute mass of the liver and muscular stomach. The use of betaine-aldehyde had no negative effect on the organoleptic indicators of the experimental poultry meat.
