Abstract
The article presents the results of research on the use of feed additives (E-selenium, Butophan OR, Nitamine OR) when keeping chickens in the period of 20–29 weeks of age. It was found that the intensity of egg laying in the experimental groups during the study period was 1,6–2,6% higher than in the control group. Minimum feed consumption (1,33 kg per 10 PCs. eggs) was set in the 2nd and 3rd experimental groups, which was lower than in the control group (by 0,02–0,1 kg). In all experimental groups (except the 1st), 100% safety of livestock was registered. In addition, a significant influence of the studied preparations on the commercial quality of eggs was established. In all experimental groups, the average egg mass was 0,5–2 g higher, and the total egg waste was 2,4–3,8% lower than in the control group. The maximum egg mass was registered in the 2nd, 3rd and 4th experimental groups. Egg incision was minimal (2,4%) in the 3rd experimental group. In the control and experimental (1st, 2nd and 4th) groups, these indicators were 3,28, 2,77 and 2,55%, respectively. There was no egg fight in 3 experimental groups, and in all the others it varied within 1,2–1,73%. Shell abnormalities were registered only in groups 1 and 2 (0,97; 1,19%) versus 1,48% in the control group.
