Evaluation of the effectiveness of treatment of cows with persistent ovarian corpus luteum

Abstract

The article presents the results of studies on the use of the drug regostenol in persistent ovarian corpus luteum. The studies were carried out in JSC "PZ" Meliorator "of the Saratov region, where they noted the widespread obstetric and gynecological pathology in cows. Among these diseases, 43.91% are functional disorders of the ovaries. Persistent corpus luteum was recorded in 12.69% of animals. After the use of regostenol, 91.67% of cows showed the stage of excitation of the sexual cycle, and the time for the onset of the first sexual cycle came in 5.2 ± 0.03 days. In the control group of cows, no manifestations of sexual cyclicity occurred. Experimental studies have shown that after the use of regostenol in cows with a persistent corpus luteum, 75.0% of animals became pregnant with an insemination index of 1.8. Whereas in the control group, all animals remained infertile. The data obtained indicate the expediency of using the drug, since it allows achieving the manifestation of sexual cyclicity after prolonged anaphradesia and fertilization of most of the cows after insemination.
