Beef production in conditions of stable-pasture and industrial technologies in breeding farms

Abstract

The article presents data on the comparative study of beef production in the conditions of stable-pasture and industrial technologies. For this purpose, in the first series of experiments in the breeding farms of Antonovskoye CJSC and Energia LLC, 40 black-and-white bulls (group 1), Kalmyk (group 2) and Hereford breeds (group 3) were formed. Black-and-white bulls were individually kept in a dispensary, 15-day-olds were grouped into 20-30 heads and were tied up in a calf coop using farm pastures. Calmyk and Hereford bulls up to 7-8 months of age were raised in both farms with mothers on full suckling. After weaning from mothers, 20 8-month-old bulls from each group were kept together, in conditions of stable-pasture technology with the expectation of obtaining 800-900 grams of daily gain. 20 8-month-old bulls of each group for the second series of tests were implemented for rearing at the Agro-Park-Razvilnoye industrial complex LLC and had free access to self-feeders with concentrates and coarse feed. In the first series, the daily increase was 749-804 g, and in the second series – 1275-1360 g, with an advantage in favor of gerefords. Therefore, the live weight of 18-month-old bulls, respectively, by birth was 619.0; 646.6 and 657.7 kg, or 178-192 kg more than with stable-pasture technology (P>0.999). At the control slaughter, the Herford bulls were highly reliably superior in both series of experiments in terms of carcass weight, muscle tissue and slaughter yield. However, the profitability of production in the first series of experiments is 1-2% higher, and the live weight is 29-30% lower.
