The effect of intrauterine infusion of 2% povidone iodine solution on the reproductive performance of repeat breeder cows was examined. Sixty (50) repeat breeder dairy cows were randomly divided into two groups: (a) the treatment group was given intrauterine infusion of 50 ml of 2% povidone iodine 24 hr after insemination, and (b) the control group was left untreated.
Results showed that in the treated group, the average number of days open was 169.84 days; the number of services per conception was 1.54; conception rate at first treatment after service was 53.3%, and overall conception rate was 86.7%. The corresponding figures in the control group were 207.9 days, 2.05, 16% and 66.7%. AU reproductive indices used were superior in the treatment group than that of the control group, and were statistically significant (P<0.05) except for the overall conception rate.
Thus, intrauterine infusion of 2% povidone iodine was found to improve the reproductive performance of repeat breeder cows particularly in shortening the number of days open, lessening the number of services per conception and increasing the conception rate.
