Meat Productivity of Cattle of French Meat Species in the Conditions of the Northern Trans-Ural Region |
|
|
The article presents the results of the scientific and economic experience in the cultivation and fattening of cattle of French meat breeds limusinsky, Charolais, obak and salers in the conditions of the Northern Trans-Ural region. The data obtained were compared with the data on the Hereford breed of cattle. As a result of the conducted studies it was established that the breed of animals had a significant effect on the magnitude of the live mass. At the age of 18 months, the largest weight was in the Charolais breed, the lowest in the Hereford breed.
Intensive cultivation affected the formation of the meat type of the physique of animals, they formed a broad-bodied body type with well-defined meat forms. This was confirmed by a control slaughter. Bulls of all breeds gave heavy, well-groomed mascara.
The lightest paired carcass was obtained from the Herefordian animal - 263.0 kg, in the second place in terms of the carcass size were the animals of the salers-284 kg, then in the form of 297 kg, but the difference in the weight of the carcass is not reliable. The heaviest carcass was obtained from bulls of the Charolais breed, it was more than from the Hereford bulls, by 79 kg (P≥0.99), and the limousine by 45.9 kg (P≥0.95). Accordingly, the highest yield of carcass (58.3%) was in Charolais breeds. The greatest yield of internal fat was in animals of the Hereford breed: 4.9%, or 12.9 kg.
The highest yield of muscle tissue is observed in the Charolais animals – 74,9%, in the second place the Limousine breed – 73,9, the third place - Hereford breed – 73,0%, further – 70,9 and the salers finish – 70,0%.
