Forty-two crossbred dairy cows or heifers were randomly allocated to two treatments: T1 (n=22) – control group, without hormonal treatment; T2 (n=20) – treated group with buserelin in the fourth day after embryo transfer, to evaluate the effect of hormonal treatment on the pregnancy rate and plasma concentrations of progesterone in bovine embryo recipients. Blood collection samples for plasma obtainment were realized on day of embryo transfer (day 0) and every other day, in a total of five samples per […]

This experiment was carried out to verify the effect of the administration of different doses of GnRH (buserelin) analogue on the emergence of a new follicular growth wave and the number of recruited follicles from this wave, accessory corpus luteum formation, the dominant follicle diameter and the spontaneous corpus luteum on the luteolitic administration day and subsequent synchronization rate and the interval between the PGF2α application and the estrus manifestation. Twenty crossbreed female cattle in diestrus, crossbred Holstein x Zebu […]
