Abstract

Two trials were conducted to determine the effects of Alfaprostol, a prostaglandin F2 alpha analogue, and uterine palpation on reproductive performance in postpartum beef cows. In Trial J, 143 multiparous and 132 primiparous Brahman crossbred embryo recipient cows were assigned to receive one 5 mg injection of Alfaprostol between 29 and 65 d postpartum or to serve as controls. Alfaprostol treatment between 29 and 42 d postpartum decreased (P < 0.05) postpartum interval in multiparous but not primiparous cows. Alfaprostol treatment increased pregnancy rate to embryo transfer. Trial II utilized 369 multiparous Brangus cows, 17 to 49 d postpartum, that were assigned to one of three groups: 1) Alfaprostol plus uterine palpation (APP), 2) Uterine palpation only (UP) or 3) Control. Completion of uterine involution was determined at treatment. Alfaprostol plus uterine palpation decreased postpartum interval regardless of uterine involution, while UP had a greater effect if uterine involution was not complete. Both APP and UP increased the number of cows which were detected in estrus by 80 d postpartum. Alfaprostol and uterine palpation, alone or in combination, can increase postpartum reproductive performance in Brahman crossbred and Brangus beef cows.
