We developed an effective technology of reproduction in meat cattle breeding, which allows rational use of the bulls-producers, to obtain a high output calves (85-95%), to organize the accuracy of the account of the origin of young animals, to improve the level of selection-breeding work on the improvement of productive and breeding qualities of animals and create in a shorter time highly productive herds of meat cattle
The features of milk production of Holstein Friesian
imported heifers to Krasnodar region from Germany with a view of linear supplies and their ancestors on the main indicators of productivity and breeding value are shown. A comparative analysis of the productive qualities of the German Holstein-Friesian with Black Pied cattle domestic breeding is made. The ways of the effective use of the Holstein Friesian German-breeding to create a highly productive dairy cattle herds in the North Caucasus are outlined
Obtaining a high intensity of growth calf in dairy period contributes to the feeding of the high daily doses of milk (8-10 kg) and schooling to early eating plant forage, which increases their live weight by 11.4-15,1%, growth energy - 13,2-16.5% and reduces the cost of feed per 1 kg of body weight gain of 4.6-8,6%
