Fourteen anovulatory postpartum (38.0 ± 1.9 d) beef cows that ovulated after an injection of 250 µg gonadotropin releasing hormone (GnRH) in saline were used to examine the influence of indomethacin on luteal function. Beginning the d after GnRH, 6 cows were given intrauterine infusions of indomethacin for 14 d and the other eight cows received vehicle. After GnRH treatment, concentrations of progesterone in serum were elevated longer (P<.01) for indometacin treated cows than for vehicle-treated cows. At the same time prosta glandin metabolite (PGFM) concentrations were lower (P<.01) in indomethacin treated cows than in vehicle treated cows. In summary, indomethacin suppressed PGFM concentrations and enhanced function of corpora lutea induced in postpartum suckled beef cows. |
