Prevention of subclinical endometritis in cows with Thiocephur drug

The aim of the study is to investigate the efficacy of Thiocefur for the prevention of subclinical endometritis in cows belonging to AO PZ Meliorator, Saratov Region. The object of the study was cows with subclinical endometritis. The diagnosis of pathology of childbirth and the postpartum period, functional disorders of the ovaries was made based on the analysis of zootechnical records, rectal and vaginal examinations, and subclinical endometritis was diagnosed according to the method of N.A. Flegmatov. When studying the efficacy of Thiocefur for the prevention of subclinical endometritis in cows, one experimental and one control group of animals were formed according to the analogue principle, with 36 heads in each. After delivery of the fetus and separation of the placenta, the cows of the experimental group were administered Thiocefur intramuscularly at a dose of 1 ml per 50 kg of animal weight once a day for 3 days (1-2 mg of ceftiofur per 1 kg of animal weight). Active ingredient: antibiotic ceftiofur sodium. Manufacturer: Republic of Belarus. The results of the conducted studies indicate a wide spread of obstetric and gynecological pathology in cows. The most common is retention of placenta (42.92 %). Endometritis was detected in 50.0 % of cows after calving, of which 34.43 % were subclinical. Intramuscular administration of the drug Thiocefur intramuscularly, at a dose of 1 ml per 50 kg of animal weight, once a day for 3 days after calving, allows to achieve an increase in the fertilization rate of cows by 5.55 % with a better insemination index (2.17). The results of the conducted studies allow us to consider it appropriate to use the drug Thiocefur for the prevention of subclinical endometritis in cows after calving.
