Abstract

More and more probiotics are used in poultry feeding. Understanding that the inclusion of beneficial microorganisms in the diet contributes to the normalization of intestinal microflora serves to prevent metabolic disorders, improves the activity of the gastrointestinal tract, increases immunity and, as a result, has a positive effect not only on the health of the bird, but also on its productivity indicators. Therefore, the purpose of our study was to establish the effect of the probiotic Levusell SB Plus on the productive qualities of hens in broiler breeders. The experiment was carried out in the production conditions of Kamenskaya Poultry Farm LLC, Kamensky District, Altai Territory on hens of the parent stock of the Ross 308 cross. The use of the probiotic Levusell SB Plus at a dose of 1.0 kg/t as a part of the complete feed for laying hens of the parent stock at the age of 23 to 63 weeks led to an increase in poultry livability, an increase in the total egg production and the intensity of egg-laying capacity. The addition of a probiotic to the poultry ration contributed to the optimization of the egg weight, an increase in the yield of hatching eggs, an increase in the hatch of chickens and the yield of broilers per initial layer by 3.9%.
