This work aimed to study the effect of PGF2α administration on anestrous post-partum period in 80 goats, with continuos or controlled suckled, rised in semi-extensive system with water and mineral salt ad libitum. The females, with age between two and six years, were randomly distributed in three groups (GI, GII, GIII). The females of GI (n = 30) received 250µg of PGF2α in vulvar muscle on days 6th and 12th after delivery. The females of GII (n = 30) received the same treatment of Group I, but every day from days 6th to 10th after delivery. The GIII (n = 20) was the control group. The estrous detection was made by using teasers and the mating with bucks with confirmed fertility. The obtained data were analyzed by ANOVA and by analysis of standard errors of difference among proportions. Difference in the occurrence of estrous among the three experimental groups was not observed (P > 0.05), however the average time of post partum anestrous was significantly reduced (P < 0.05) in animals treated with PGF2α. It was also detected a relevant reduction (P < 0.05) of post-partum anestrous in females with controlled suckled. Difference was not registered (P > 0.05) on pregnant percentages among the different groups. It may be concluded that the administration of PGF2α in the beginning of puerperium in caprine is efficient to reduce the anestrous pos-partum period, specially in females controlled suckled; however do not influence the fertility in meat goats. KEY WORDS: Caprine, estrus, puerperium, prostaglandine.
