Sixteen cows following parturition were selected at 35–50 days postpartum, randomly and equally divided into two groups as group I and II. All cows were orally supplemented with 30–50 grams mineral mixture daily continuously for 15 days. Group I cows were treated with ovsynch protocol between 50th and 65th day post-partum. The percentage of ovulatory response was 100.00 and 62.50 percent in group I and II, respectively. The first service, second service and overall conception rates observed were 37.50, 50.00 and 87.50 and 25.00, 37.50 and 62.50 percent in group I and II, respectively. It is concluded that mineral mixture plus ovsynch protocol improved the conception rate in postpartum dairy cows.
