Influence of enzyme preparations on the growth and development of Ross-308 cross meat chickens
Abstract
The studies were carried out in 2017-2018 in the poultry farm of OJSC JV firm “Virtech-Agro” (joint American-Russian-Uzbek enterprise), which is located in the Zangiata district of the Tashkent region, 25 km from the city of Tashkent, Uzbekistan. As a result, the characteristics of broiler chickens of the Ross-308 cross, technical conditions of use and characteristics of flavomycin, its effect on the growth of chickens and on the quality of feed during long-term storage, the effect on the digestive process and pathogenic microflora in Uzbekistan were studied. The results obtained show that the use of these components shortens the broiler rearing period from 38 to 42 days, increases weight gain, improves the meat quality of chickens, reduces feed costs and, at the same time, reduces labor costs for workers.
