Determining the fertility of juvenile gilts of large white breed
Abstract
Main indicators of good productivity of number of sows on pig farms are: high percent of successful insemination, number of fetuses and vitality of piglets. Now there is no universal methods of diagnostics of fertility that can be used on practice. The reproductive potential of each pig is judged after the fact, after the first or second farrowing. That is why, an indirect judgment about the future productivity of gilts through the determination of hormones during puberty can significantly reduce the economic losses for the maintenance of low -producing gilts.
In order to establish the hormonal status of gilts, we determined the concentration of sex hormones (Е2) and Müller-inhibiting hormone in the blood serum.
Our studies of the level of anti-Müllerian hormone (AMH) using enzyme-linked immunosorbent assay in blood serum proved the possibility of early assessment of fertility in pigs. This method will allow early culling of low-yielding gilts from the broodstock.
Further development of methods for determining the fertility of pigs, as well as conducting testing for the level of antiMüllerian hormone by ELISA in the mandatory gynecological clinical examination of gilts at pig breeding enterprises is economically feasible and effective.
