The objective of this work was to determine the effect of antral follicle number (AFC) on the conception rates of Nellore females, in a fixed‑time artificial insemination (FTAI) program. For that, 481 females were subjected to a FTAI protocol and evaluated for antral follicle counts (AFC) and pregnancy diagnosis. The animals were grouped into the AFC categories considered as low (<34 follicles), intermediate (34–53) and high (>53). There was no difference between the conception rates obtained for the AFC categories in FTAI protocol with use of chorionic gonatropin.Downloads
