title: The effects of gonadotrophin releasing hormone administration in early postpartum dairy cows on hormone concentrations, ovarian activity and reproductive performance: a review.
abstract: Gonadotrophin releasing hormones have become widely used hormonal compounds in veterinary medicine, particularly with respect to bovine reproduction. The character and physiological actions of gonadotrophin releasing hormone are briefly reviewed and its clinical applications are summarized. The endocrinological research concerned with the use of gonadotrophin releasing hormone in the early postpartum period is discussed. Field trials which have been conducted to assess the effects of postpartum gonadotrophin releasing hormone administration on reproductive performance have varied widely in both design and interpretation of results. These experiments are reviewed, including the clinical trials using normal cows as well as those on cows with retained placenta.
