Teza

In the conditions of constant reduction of number of cattle, which is accompanied by increase in the number of cows in the herd and simultaneous increase in plume cattle in our country becomes a little more extensive. This has led to a sharp reduction in livestock production. Therefore, along with the adoption of a complex of organizational, economic and technological measures necessary to increase the intensity of use of the genetic potential of highly productive producers. To improve the efficiency of large-scale selection, which provides a permanent increase in milk yields need to increase the intensity of selection of the best bulls on quality of posterity. Along with this, it is necessary to intensify the process of structural changes of species composition of animals that meet the increasing requirements of the economy. Given the situation, it becomes apparent that the use of traditional methods of play can not solve the problems the livestock problems. In these conditions the special urgency of the activities aimed at improving the organization of the reproduction on the basis of modern biotechnological methods, which have already been approved in cattle and can be used in the reproduction of other species. Primarily these include biotechnological method embryo transfer, which is based on the principles of purposeful regulation of reproductive functions. In this sense, it should be noted that scientists have developed a new technology of transplantation of embryos, allowing for the basic parameters (1112 ovulation and 55-60 quality embryos per donor, 55 calves per 100 embriodered), to be at par with the best world analogues. Hence, in breeding programs the use of the method of embryotransfer allows to intensifythe breeding progress by use of the genetic potential, which is a reserve gene pool of cattle. Transplantation method in the practice of pastoralism is also used for rapid recovery of the number and wide distribution of rare and endangered species, the accelerated establishment of herds of cows recordist, create a Bank of cryopreserved embryos and their subsequent transfer in herds. Obviously the advantage of this method for imports and exports of agricultural animals.. However, it should be noted that the method of embryotransfer effective at the perfect observance of the hygienic norms of the maintenance, freeding and maintenance of animals, when all process elements are performed by highly qualified specialists in healthy animals. The main prospect of the development of the method of transplantation should be the development of new methods allowing obtaining the maximum number of calves from the animals with the desirable genotype.
