Abstract
This article presents the results of a study on the efficiency of fertilization by treatment with ovariovit and liarsin. The study was conducted on the facility of “Kamyshinskoe” farm in Shemonaikhinskiy region of Vostochno-Khazakhstanskaya oblast in the Republic of Kazakhstan. Animals of different ages and with the same productivity were selected for the experiment. Treatment of animals was carried out after gynecological clinical examination. The examination of animals was performed by rectal and biophysical methods. The efficiency of homeopathic and hormonal treatments of the dairy cows to increase fertility were studied. The performed study enabled evaluation of various schemes for increasing the fertility of dairy cows. The results of the study showed a higher efficiency with the treatment of homeopathic drugs.

The results of the present study showed the following results: Table 2 Results of the use of drugs to increase fertility in dairy cows
The results of the present study showed that monotherapy for infertility in cows is inefficient, so it is necessary to develop and implement new methods of treatment
Summary
Modern technologies applied in animal breeding are associated with stress factors that impact animals. Because of worsening of live-stock handling conditions, feed quality and veterinary care, the number of cows with health issues is increasing, which inevitably leads to livestock reproduction rate reduction, and as a result, decrease of milk yield. It is established that cows that remain infertile within a year, have their milk yield reduced by 3050% and sometimes by 70% In such conditions with varying levels of incorporated technology, these issues in live-stock reproduction persist. Reproductive organs pathology is one of the reasons of uterine infertility in bovine live-stock, under-delivery of calf crop and decrease of its survival rate. The most important fact is the decrease of insemination rate and milk productivity because of pathologic delivery and postpartum period. It is established that insemination rate decreases by 17–40% and calf crop and milk productivity – by 12–18% (Beam and Butler, 1999)
