Effects of dietary butyrate supplementation and oral nonsteroidal antiinflammatory drug administration on uterine inflammation and interval to first ovulation in postpartum dairy cows

Cows experience postpartum uterine inflammation (endometritis), which may consequently delay ovulation. We evaluated whether the oral administration of a nonsteroidal antiinflammatory drug (NSAID; meloxicam) and the dietary supplementation of butyrate could reduce endometritis, determined by polymorphonuclear leukocytes (PMN), and reduce the interval to first ovulation. There were no differences between butyrate and control-fed cows for any of the parameters assessed. Mean interval to first ovulation did not differ between NSAID and placebo-treated cows, but NSAID-treated cows tended to have a lower ovulation rate up to 56 days postpartum compared with placebo-treated cows. Oral NSAID administration and dietary butyrate supplementation during the transition period were not effective in reducing endometritis and interval to first ovulation.
