Abstract

Cows remaining open for more than 150 days after calving were randomly divided into three groups and treated. Group A (n=20) was treated with Nelex® on Day 1 (day of beginning treatments), cloprostenol on Day 20 and Nelex® 24 hours after breeding. Group B (n=32) was given Nelex® on Day 1 and cloprostenol on Day 20. Group C (n=332) were treated with cloprostenol upon detection of a corpus luteum. Definite oestrus expression within three days after cloprostenol administration was exhibited in 50% of the animals in groups A and B and 25% of those in group C. Pregnancy rates for groups A, Band C were 65.0, 59.4 and 40.6% respectively. These results suggested that Nelex® in combination with cloprostenol  could  improve  oestrus expression and fertility of postpartum cows
