Treatments to Induce and Control Ovulations and Reduce the Incidence of Abnormal Luteal Phases in Postpartum Suckled Beef Cows
Abstract
dc:descriptionAnestrous postpartum suckled beef cows can be induced to ovulate by gonadotropin releasing hormone (GnRH) but the luteal phase following that ovulation is generally six to twelve days long. It was hypothesized that the presence of a luteolytic compound (prostaglandin F(,2)(alpha)) and the duration of the GnRH-induced LH surge are causes of the abnormal luteal phase. The aim of this dissertation was to determine the cause of abnormal luteal phases and to develop a procedure to induce and control fertile ovulations in both anestrous and cyclic postpartum suckled beef cows.
