The effect of the biologically active additive betaine-aldehyde on the meat productivity of quails

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