| Title : | EFFECTIVENESS OF BUSERELIN IN EARLY PUERPERIUM ON RESTORATION OF OVARIAN CYCLICITY AND SUBSEQUENT CONCEPTION IN PRIMIPAROUS DAIRY COWS |
| Abstract : | The postpartum period is an important period in the reproductive life of both dairy and beef cows due to its great influence on subsequent pregnancies. A major reproductive problem on dairy farms is the delayed restoration of postpartum ovarian activity, which is reflected in a prolonged intercalving interval, where farmers suffer large economic losses. Dairy cows have between two and five months after parturition to become pregnant again if reproductive capacity and productivity are to be kept in desirable range. Utilisation of hormones is quite common in dairy industry, but to achieve improvement in reproductive performances they have to be used with caution. The study was focused on the restoration of the ovarian cyclicity in the early postpartum period and the reduction of the service period, where a total of 50 primiparous Simmental cows were divided into experimental and control groups. The experimental group was treated with the hormone buserelin, hormonal MSD preparation - Receptal®, which is a GnRH agonist was used in dose of 5 ml on the 10th, 11th, 12th, 13th or 14th day postpartum for earlier restoration of ovarian cyclicity. It is expected that about 30-40 heifers will require some assistance during parturition. A slightly higher number of animals had earlier restoration of ovarian cyclicity and had more conception in the experimental group in contrast to the control group. Buserelin applied at day 13th or 14th looks to be relatively efficient in shortening the service period and intercalving interval in primiparous simmental cows. |
