Evaluation of methods for overretained afterbirth expulsion in cows

Abstract

The article presents the results of the overretained afterbirth expulsion in cows. It was found out that retention of placenta is recorded in 39.04% of cows. Most often, incomplete retention of placenta was noted in 36.98%,  and complete one in 2.05%. The efficiency of afterbirth expulsion with uteroton was 58.82%, with metrostim and metrostim in combination with enroflon - 64.71%. Fertility of cows turned out to be the highest after intramuscular use of metrostim in combination with intrauterine administration of enroflon (76.47%) with the best insemination index (1.6±0.01). According to experimental studies, for a conservative method of  overretained afterbirth expulsion in cows, it is advisable to use a myotropic drug in combination with a drug that has a bactericidal effect on the microflora of the uterine cavity. This helps to accelerate the involution of the uterus, increase fertility and prevent the occurrence of various forms of endometritis.
