Animal Nutrition and Health

The breed is a factor that determines the productivity of cattle.In the domestic and foreign literature there are numerous data on the economic characteristics of meat breed cattle but there is little reliable information about the productive features of a particular breed in the conditions of a certain region.In this regard the study of the productivity of beef cattle of different breeds in the conditions of the Kurgan region is an actual problem.The studies were conducted in the farms of Kurgan region in 2013-2014 on the young Aberdeen-Angus and Hereford breeds.It was established that the main reserve of beef production in Kurgan region is the intensive growing and fattening of the young Aberdeen-Angus and Hereford breeds (31.53 and 63.51% respectively, of the total number of livestock).The animals of the Aberdeen-Angus breed showed better productivity and economic efficiency in comparison with the Hereford animals: a body weight of 524.55 and 476.80 kg in 18 months, a slaughter yield of 61.2 and 60.8%, a protein conversion ratio of 16. 31 and 16.15%, the level of profitability of 20.98 and 13.91% respectively.During the entire period of cultivation (0-18 months) the animals of the Aberdeen-Angus breed consumed a smaller amount of EFU (energetic feed unit), exchange energy and digestible protein per 1 kg of body weight growth -6.23 EFU, 62.25 MJ and 540 g.The breed factor influences a significant effect on the average daily weight gain (12.82%), dry matter content in the pulp (42.27%), fat content in the pulp (73.72%), energy value of the pulp (58.95%), conversion rate of the energy exchange (59.14%).To increase the production of beef in Kurgan region it is recommended to breed the animals of the Aberdeen-Angus breed.
