The feasibility of using a probiotic to increase the egg productivity of chickens

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