Sincronización del estro en ovejas de pelo mediante protocolo basado en prostaglandinas + GnRH

Abstract: El uso de progestágenos puede contaminar el medio ambiente y el tejido animal, por lo que el uso de prostaglandinas F2α (PGF2α) y hormona liberadora de gonadotropinas (GnRH) pueden representar una alternativa viable. El objetivo del presente trabajo fue evaluar el efecto de aplicar una dosis de GnRH en el intervalo de aplicación de dos dosis de PGF2α, y compararlo con protocolos basados en progestágenos y PGF2α, comúnmente utilizados en la sincronización de estros, con respecto al pico pre-ovulatorio de la hor… Show more

“…It is a technology that enables the ewes within the herd to accept mating and pregnancy during the same time or close times of the year [40]. The Optimal Use of these technologies in reproductive function enables us to tune in to estrus, increase the rate of ovulation, and the appropriate timing of IVF, which, in turn, increases the reproductive efficiency of agricultural animals [41].…”

“…CL regression is attributed to the action of prostaglandins, ending diestrous and triggering proestrous (3 and 2 days for cattle and sheep, respectively) (Atuesta and Diaza, 2011). This results would enable an estrous response the following day, basing its action within 72 h in sheep (Thimonier 1981;Ávila-Castillo et al, 2019) and 96 h in cattle (Córdova et al, 1983;Liu et al, 2017Liu et al, , 2018. In published reports, the period considered is greater than the effect attributed to the action of prostaglandin.…”
