The Effects of Administering Estradiol Benzoate Plus Progesterone During the Growth or Static Phases of the Dominant Follicle in CIDR-Treated Lactating Dairy Cows
Abstract:Abstract.We studied the effects of administering estradiol benzoate (EB) plus progesterone (P4) as part of a CIDR-based protocol during the growth or static phases of dominant follicle development on follicular wave emergence, follicular growth, synchrony of ovulation and pregnancy rate following CIDR withdrawal, treatment with PGF2α and GnRH, and fixed-time artificial insemination (TAI). Forty-one previously synchronized lactating Holstein dairy cows were randomly allocated to three treatment groups. The cont… Show more
