REPRODUCTIVE QUALITY HEIFERS SIMMENTAL, AND LIMOUSIN BREEDS AND THEIR HYBRIDS OF DIFFERENT GENERATIONS
In beef cattle the lasttime are widely used genetic resources of the Simmental breed. This is due tothe high productive qualities, longevity Simmental. At the same time, thecattle of this genotype is not fully adapted to the breeding technology of beefcattle. Animals are not high enough mothering and calving difficulty. In thisregard, the most effective breeding technique is the use of Simmentalinterbreeding as the mother base. Cattle of specialized meat breed –Limousin-became very popular in beef cattle breeding in many countries. Animalsare characterized by high meat and maternal qualities easy calving. At the sametime, a characteristic feature of the animals of this genotype is not highenough adaptation to the conditions of the sharply continental climate.Promising in this regard is the crossing of Simmental cattle with limousinesand the creation on this basis of crossbred breeding herds in order to determinethe effectiveness of crossing these breeds of animals, we have studied thereproductive qualities of the initial breeds of animals and their hybrids ofdifferent generations. The results of studies indicate a fairly high level ofreproductive abilities of young crossbreeds. As a result, the crossbredbreeding stock obtained by crossing cows of Simmental breed with limousines canbe effectively used in the formation of crossbred, uterine herds.
