The article analyzes the scientific data and own research on study and formulation the preventive efficacy of ketoprofen during embryonic mortality in cows for estrus synchronization, depending on the duration of the period after birth. It is known that in cows at spontaneous recovery of sexual cyclicity after calving for its next synchronization form smaller corpus luteum, although their fertilization is higher than in animals without sexual cyclical recovery after giving birth to synchronize estrus. The application for cows with small yellow bodies of NSAIDs inhibit the production of prostaglandin F2α by uterine lining through blocking Cyclogenesis of type II. Stimulation and sexual cyclical synchronization was performed using surfagon and estrofan and at the 10th day cows were inseminated. Animals of the experimental subgroups at the 11th day after insemination were injected in therapeutic dose NSAIDs ainil. The prophylactic use of ainil towards embryonic mortality after insemination of cows for previous estrus synchronization promotes animal insemination by average of 7.3%. Such effect of NSAIDs on cows fertilization depending on the period after calving can point to the prevention of fetal death in animals with restored sex cycles after calving regardless the cause of the formation of the corpus luteum at spontaneous manifestation of the sexual cycle or estrus synchronization.
