Open-access Fertility of Nellore females after a fixed‑time artificial insemination according to antral follicle count

AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    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.
