The efficiency of growing Hereford cattle of the Andrianov type with year-round grazing

Abstract

Relevance . Increasing beef production and reducing costs is one of the main tasks of the agro-industrial complex. In this regard, it is necessary to develop a resource-saving technology for growing Hereford cattle with year-round grazing. OOO "Andrianovsky" of the Bogradsky district of the Republic of Khakassia — a breeding reproducer for the Hereford breed of cattle of the Andrianov type. The productive and reproductive abilities of cows, the dynamics of the live weight of young animals from birth to 18 months of age, the meat productivity of bulls were studied, and the efficiency of keeping Hereford cattle with year-round grazing was calculated. Results . The technology of breeding animals provides for their year-round grazing using light-weight premises during adverse weather conditions. The average daily increase in cows from calving to weaning of calves was 387 g, the service period was 85 days, the calving interval was 378 days, the coefficient of reproductive capacity was 0.97, the yield of calves per 100 cows was 92%, the safety of young animals was 98%. Live weight at weaning at 8 months of age in bulls was 228 kg, heifers — 224 kg, at 18 months — 520 and 447 kg, respectively. The average daily gain for the entire period of growing in bulls was 912 g, in heifers — 781 g. Keeping animals in light-weight premises with year-round grazing makes it possible to grow bulls to high slaughter conditions (carcass weight — 302.7 kg, yield — 59.7%, meat index — 5.0%) and get heifers suitable for insemination at the age of 16 months with a live weight of 400 kg. The calculation of the economic efficiency of growing animals of the Hereford breed of the Andrianov type with year-round grazing showed high profitability — 46.6%. To increase the production of beef, we recommend using a resource-saving technology for growing beef cattle in the conditions of the steppe zone of Khakassia.
