Through a transrectal ultrasonography (Aloka SSD 500 microplus equipment, linear transducer of 7.5 MHz) a total of 267 observations were performed in a group of 50 females mainly Bos indicus, raised under humid tropical conditions and pregnant from day 20 every other day until day 40 post artificial insemination (AI). The objective was to measure the size of the amniotic vesicle and the longitudinal and transversal axis of the embryo, to determine the day in which it is possible to measure this structure and detect the heart contractions in the screened embryos. The accuracy in identifying the amniotic vesicle was 60% (12/20) on day 20 of the first screening with embryos having an average length of 0.44 ± 0.20 cm. Accuracy in detectin...
