PREVALENCE, DIAGNOSTICS AND PREVENTION OF EMBRYONIC MORTALITY IN COWS

Abstract

The authors of the work recommend using the commercial Bovine Pregnancy Test Kit for ELISA research and the ELx808 microplate reader (microplate reader) for the early diagnosis of pregnancy in cows by the method of determining the blood serum content of specific pregnancy-associated glycoproteins (PAG) from day 26 after artificial insemination cows. The prevalence of embryonic mortality in cows of Medeu Commerce LLP was 22.22%. It was found that the determination of the PAG content on day 26 after artificial insemination and rectal examination on days 60-65 after artificial insemination is an affordable and accurate method for diagnosing embryonic mortality in cows. Under the conditions of the economy, for the prevention of embryonic mortality, intramuscular administration of a 2.5% oil solution of progesterone at a dose of 10 ml should be used on days 5 and 7 after artificial insemination, this method allows to reduce embryonic mortality by 8.24%.
