Therapy of ovarian dysfunction in cows in the conditions of farms of the udmurt republik

Abstract

Increasing the reproductive qualities of animals is the main task of dairy farms. Replacement of the main breeding stock with young animals, often leads to the fact that young animals, being exposed to ovarian diseases, undergo a longer recovery time and reduce the effectiveness of artificial insemination. This work highlights the issue of infertility of cows in specific farms, under certain feeding and housing conditions. The aim of the work was to develop a system therapy of infertility of cows with ovarian diseases.The experiment was conducted in two farms of Uvinsky district of the Udmurt Republic, with the formation of six groups of animals in each farm for each individual disease. In particular, the main diseases were ovarian hypofunction and ovarian follicular cysts. Six schemes of ovarian therapy were developed.During a gynecological examination, hypofunction of the ovaries was found in 14% of cows in the SPK "collective farm Udarnik" and in 18% of cows in OOO "Riko-Agro". Follicular ovarian cysts were found in 10% of cows in the SPK "collective farm Udarnik" and in 12% of cows in LLC "RikoAgro". During the experiment, the activity of the manifestation of sexual characteristics in cows was monitored. At the same time, it was found that with hypofunction of the ovaries, all experimental cows came into heat only according to scheme No. 2. This scheme includes drugs such as Surfagon and ASD-2fr emulsion. and Tetravit. In the treatment of follicular ovarian cysts, attention was paid to the regression of cysts. The greatest amount of cyst regression (100%) was achieved using scheme No. 5, which includes Metrostim, Fertagon and Estrofan. As a result of the work, we found that in the case of ovarian hypofunction, the most effective treatment regimen included Surfagon, ASD-2fr. and Tetravit. The rate of cow fecundation was over 67% of cows in both farms on the first insemination. With follicular ovarian cysts the greatest efficiency of therapy was achieved using the scheme including Metrostim, Fertagon and Estrofan.Fertilization of cows at the first insemination after therapy was also more than 80%. For the purpose therapy of these diseases, we recommend to use schemes including the above mentioned drugs.
