Abstract	Resumo: Objetivou-se desenvolver um protocolo hormonal que viabilizasse um melhor momento da IATF com semen sexado. Para isso, 60 femeas foram avaliadas por palpacao retal e ultrassonografia e consideradas aptas a reproducao. Em um dia aleatorio do ciclo estral (D0), as 16:00h os animais receberam um dispositivo intravaginal de progesterona (DIB®, MSD Saude Animal) associado a 2mg de Benzoato de Estradiol (BE) por via intramuscular (i.m.) (Gonadiol®, MSD Saude Animal). No D8, as 16:00h os dispositivos intravaginais foram retirados e aplicou-se 300U.I. de eCG i.m. (Novormon®, MSD Saude Animal) e 500μg de Cloprostenol i.m. (Ciosin®, MSD Saude Animal). No D9, as 18:00h aplicou-se 1mg de BE i.m. e no D11, as 6:00h os animais foram divididos aleatoriamente em dois grupos: G1-CONV (n=30), animais inseminados com doses de semen convencional e G2-SEX (n=30), animais inseminados com doses de semen sexado. O diagnostico de gestacao foi realizado por ultrassonografia transretal, 30 dias apos as IATFs e as analises dos dados, executadas pelo teste do qui-quadrado (2) disponivel no Statistical Analysis System (P<0,05). Dos 60 animais inseminados, 30 ficaram prenhes (50,0%). A taxa de concepcao entre os grupos experimentais nao diferiu estatisticamente, os grupos G1-CONV e G2-SEX obtiveram taxas de concepcao de respectivamente, 60,0 e 40,0%. O protocolo possibilitou aos animais inseminados com semen sexado 62 horas apos a retirada do dispositivo intravaginal, alcancarem taxas de concepcao proximas as femeas inseminadas com semen convencional.
