Serum Biochemical Changes in Relation to Some Nutritional and Hormonal Managements for Treatment of Inactive Ovaries in Buffaloes

Abstract

Summer infertility may be considered as the major reproductive problem in buffaloes. This study aimed to evaluate the efficacy of hormonal and nutritional-dependant protocols to alleviate summer infertility in buffaloes. In this study, thirty buffalo cows affected with summer infertility were used; they were divided randomly into three groups (10/each). Group-I: were administrated with propylene glycol in addition to trace element mixture (containing zinc and selenium), Group-II: received the same previous treatment with hormonal estrous synchronization (GnRH-PGF-2a- GnRH), Group-III: received only the previously mentioned hormonal treatment. The results revealed that, all the treatment protocols has succeed to stimulate the ovarian activity and follicular growth which was accompanied by a significant increase in estrogen and progesterone hormone, but, only the first two protocols have a favorable effect on metabolic-related hormones (T3, T4), serum glucose concentration and mitigation of the present oxidative stress state. All of the treatment protocols have increased the concentration of insulin-like growth factor-1. Finally, it could be concluded that combination of both of nutritional and hormonal treatment has been proved to have the best plausible effect for relieving and cure of summer infertility in buffaloes.
