Effect of bioactivated wheat grain enriched with sodium selenite on productive performance of quails

The results of the studies on the effectiveness of using wheat grain, bioactivated in two ways, in the diet of quails are presented. The studies were carried out on the quails of Japanese selection from birth to 153 days of age. At one day of age, three groups of chickens of 70 heads each were formed. The control group received the basic diet (BD). The first experimental group received BD + bioactivated with water wheat grain (20% of the weight of native grain in the feed). The second experimental group received BD + bioactivated wheat grain with sodium selenite (selenium 25 mg/l of water) (20% from the mass of native grain in the feed). It was found that during bioactivation in wheat grain of experimental groups I and II, sugar increases compared to native grain in the control group from 4.99% to 8.17 and 7.20%, with a decrease in starch from 76.23 to 72.49 and 71.95%, increasing the fat level from 1.35 to 1.51 and 1.74%, respectively. The inclusion of bioactivated grain in the basic diet of quails in the first experimental group helps to increase the viability of young quails by 4.3%, in the second experimental group – by 7.1% compared to the control group; live weight for 60 days of experiment by 6.0 and 7.2% (P≥0.99), average daily gain – by 6.5 and 7.4% (P≥0.99), reduction in feedcosts from 7.0 to 8.5%, slaughter yield – by 2.0 and 4.2%, an increase of lysine content in muscle mass from 0.73 (P≥0.99) to 0.79% (P≥0. 99). A positive effect of the activated grain in the composition of feed on the reproductive indicators was established: laying hens of the I and II experimental groups began laying eggs 3 days earlier than in the control. More eggs during the record period were obtained from laying quails of the II experimental group – 72.48 pieces, which exceeds the indicators of the control group by 8.7% and the I experimental group by 7.8%. In terms of egg mass, laying hens of the second experimental group exceeded the control by 8.2%, and in terms of the conditional economic effect in the production of marketable eggs – by 14.0%.
