Abstract

The authors conducted a scientific and economic experience in LLC "Alyona". For research on the principle of analogues from chickens of the Rhodonite-2 cross, 2 groups (400 heads each) were formed from the daily age, taking into account gender, body weight and physiological condition. The duration of rearing of the repair young was 17 weeks, after which the bird was transferred to the laying hens workshop. The planting density, light mode, and feeding front of birds of all groups were the same and corresponded to the norms of VNITIP. Feeding was carried out with the same full-fledged compound feed, balanced in all nutrients and metabolic energy, with the inclusion of a probiotic SUB-PRO in the feed mixture of the experimental group. The introduction of a probiotic into the diet when raising chickens up to 13 weeks of age ensured a higher safety of young animals in the experimental group. The addition of a probiotic reduced feed costs. During the growing period of 1-13 weeks, feed costs per 1 kg of growth were lower in the experimental group, by 3.3% for 14-21 weeks and by 3.9% during the experiment period.
