Abstract

Transrectal ultrasonographic examination of ovaries of thirty dairy cattle, showing clear cervico-vaginal
discharge at estrus, was carried out on the day of 1st artificial insemination (AI) to establish a relation between the
dominant follicle diameter and subsequent pregnancy. Pregnancy diagnosis was undertaken on day 60 post-AI.
The difference (P<0.05) between mean follicular diameter in pregnant (11.53±0.32 mm, n=10) and nonpregnant (10.16±0.35 mm, n=20) cattle suggested a relation between dominant follicle diameter at AI and
subsequent pregnancy outcome in dairy cattle.
