The present research was carried out on 25 cows of first calving and multiparous, between 3 and 5 years of age, with a single insemination in the PROLACNOR barn of the locality of Cartavio, jurisdiction of the District of Santiago de Cao. The cows were randomly selected from a group of 70 cows in production, determining embryonic death under the ultrasound method that consisted of using an ultrasound that allows us to obtain accurate results per day during the third until the seventh week of insemination; Where he evaluated the presence of the embryo during the days previously described and the moment in which it is lost observing through echographic screen absence of echogenic liquid. A pregnancy rate of 92% was obtained, with embryonic deaths between 27 and 29 days after insemination. With 11.11%, 66.67% and 22.22% for days 27, 28 and 29 respectively.
