Abstract
Aim:The study was undertaken to find out the serum metabolic and minerals profile in postpartum anestrous surti buffaloes treated with norgestomet ear implants alone and in combination with pregnant mare serum gonadotropin (PMSG).Materials and Methods:The study was conducted on 18 postpartum anestrous Surti buffaloes divided into three groups of six animals each at random to conduct the experiment. The buffaloes in Group-I and Group-II were implanted with Crestar ear implant for 9 days together with 2 ml injection of Crestar solution given i/m on the day of the implant insertion. In Group-II, additionally 500 IU PMSG was given i/m on the day of implant removal, whereas the buffaloes in Group-III served as anestrous control group and received 5 ml Normal Saline i/m on day 0 and 9 as a placebo treatment.Results:The overall serum total protein values did not differ significantly (p > 0.05) between time (days) intervals in any of the groups. The mean serum total cholesterol levels at 10th day and on the day of estrus were found significantly lower (p < 0.05) in the control group as compared to treatment Groups I and II. However, there was no significant difference (p > 0.05) at 10th day and on the day of estrus between treatment groups (T1 and T2). The overall mean serum cobalt, zinc, iron, and manganese values did not differ significantly (p > 0.05) between different time intervals among any of the groups, except copper which was significantly lower (p < 0.05) at 10th day in control group as compared to treatment groups.Conclusion:Microelements cannot be synthesized in the body. Hence, it is concluded that the mineral mixture should be supplied daily in the animals ration to suffice the requirement of the trace elements. The mean serum metabolic and micro-minerals profiles in treatment and control groups revealed that overall mean serum total protein, cholesterol, copper, and zinc levels were apparently higher in treatment groups whereas, mean serum cobalt, iron, and manganese concentration had no consistent trend between treatment and control groups of Surti buffaloes.

Summary
The postpartum period plays a pivotal role in bovine reproduction. The duration of postpartum anestrous has an important influence on reproductive performance. There are certain biochemical parameters, which directly influence the reproductive performance of animals either through stimulating hormone synthesis, hormone action or response of the target tissue by acting as precursor for hormone synthesis. Nutritional factors needed for successful reproduction are the same as those needed for maintenance, growth and lactation, that includes protein, energy, mineral and vitamins, and deficiency or excess, any of these components, which is serious enough to affect reproduction will affect other physiological functions. Lack of minerals and trace elements such as copper, cobalt, manganese, zinc, etc., upset the proper functioning of the genital organs [1]. Trace elements may function as cofactors, as activators of enzymes or stabilizers of secondary
