Effects of two estradiol esters (benzoate and cypionate) on the induction of synchronized ovulations in Bos indicus cows submitted to a timed artificial insemination protocol.
The effects of estradiol benzoate (EB) and estradiol cypionate (EC) on induction of ovulation after a synchronized LH surge and on fertility of Bos indicus females submitted to timed AI (TAI) were evaluated. In Experiment 1, ovariectomized Nelore heifers were used to evaluate the effect of EB (n = 5) and EC (n = 5) on the circulating LH profile. The LH surge timing (19.6 and 50.5 h; P = 0.001),...
متن کاملImportance of estrus on pregnancy per insemination in suckled Bos indicus cows submitted to estradiol/progesterone-based timed insemination protocols.
The objective was to evaluate the effect of estrus occurrence (based on removal of tail-head marks) on ovarian responses and pregnancy per AI (P/AI; 30 d after AI) in suckled Bos indicus beef cows submitted to timed AI (TAI) protocols. Cows received an intravaginal device containing 1.0 g progesterone, and 2.0 mg estradiol benzoate im; 8 d later, the intravaginal device was removed, and they we...
متن کاملInduction of estrus in ovariectomized cows and heifers: effects of estradiol benzoate and gonadotropin releasing hormone.
Three experiments were conducted with ovariectomized (OVX) cows and heifers to investigate potential neuroendocrine mechanisms controlling estrous behavior. In Exp. 1, 10 OVX cows were treated with either 125 micrograms estradiol benzoate and 10 cc saline (125 micrograms EB + SAL), 125 micrograms EB and 500 micrograms gonadotropin releasing hormone (125 micrograms EB + GnRH), 250 micrograms EB ...

On d 0 of the experiment Bos indicus x Bos taurus (n=130) cows received an injection of GnRH and a progesterone-releasing device called an Eazi-BreedTM CIDR® for 7 d with a prostaglandin F2a injection at CIDR removal. Upon CIDR removal cows were divided into two AI treatments: 1) injection of estradiol cypionate (ECP) 24 h after CIDR removal with AI 8 to 10 h after a detected estrus and timed-A...
