Technological platform of the development of beef cattle breeding in food supply system

Abstract

An effective method of increasing the meat productivity of livestock in herds is the industrial crossing of part of cows and heifers with producers of highly productive meat breeds. For the experiment, according to the principle of analogue pairs, 2 groups of newborn gobies were formed taking into account the live weight of the animals. The first group included Hereford bulls, the second group consisted of crossbred bulls (♀ red-motley x ♂ Hereford). We studied the productive qualities of gobies by the dynamics of growth in live weight of gobies. To assess the meat qualities, a control slaughter of experimental gobies was performed. Domestic bulls exceeded (P <0.05) pure-bred calves in live weight. For the growing period (from 6 to 12 months of age), the difference in live weight between the bulls of the first and second groups was 24.3 kg or 7.5 percent (P <0.1). When feeding on natural pastures for 90 days, the difference in live weight between the groups was between the first and second - 29.1 kg (7.3%). As a result of the experiment, the cost of production of 1 kg of beef obtained from cross-breed gobies is 1180.2 rubles lower. The profitability of growing crossbred bulls is 11.2 orders of magnitude higher. In order to increase meat productivity and improve meat quality in commodity cattle breeding, it is advisable to practice rearing and feeding of young animals obtained by crossing red-motley cows with Hereford bulls in order to raise fattening young animals using intensive technology of meat cattle breeding.
