ABSTRACT

In order to evaluate the estrous and ovulatory activities of goats submitted to estrus synchronizationwith essential oils of Vitex agnus castus L. (OEVAC), 48 Anglo Nubian goats were divided into four groups(n=12) for estrus synchronization MAP-COM group, 75 µg of D-cloprostenol was intramuscularly (im)administered and one intravaginal sponge impregnated with 60 mg of MAP was deposited and removed fivedays later when it was injected im 300 IU eCG; MAP-ART group with similar treatment of MAP-COM, butintravaginal sponges were manually prepared and impregnated with 60 mg of MAP; in the OEVAC60 andOEVAC120 groups it was performed the same as in MAP-COM, but intravaginal sponges were impregnatedwith 60 mg and 120 mg of OEVAC, respectively. The use of intravaginal sponges impregnated with 60 mg of theOEVAC it is able to synchronize estrus but not the ovulation in goats.(AU)
