| Abstract | An experiment was conducted to find serum levels of common trace elements in anestrous buffalo cows and heifers of the government farm to access the deficiency status if any. Fourteen anestrous buffalo cows and heifers were taken for the purpose, and their blood was collected, and the serum was analyzed for the level of common trace minerals such as copper (Cu), manganese (Mn), zinc (Zn), iron (Fe) and cobalt (Co). After detecting a deficiency of Cu in all the anestrous animals, a supplement with copper sulfate penta hydrate (inorganic salt of copper) was administered once a week. Subsequent estrus were recorded for a period of two months after starting the supplementation. Six out of 14 animals showed the signs of estrus in the fi rst month of supplementation, while another five animals showed signs of estrus in the second month. Hence just two months of copper supplementation brought about a dramatic response: the observation of estrus was recorded in about 80 percent of the animals, which suggested the influence of the copper requirements on the normal reproductive performance of the animals. Thus, it may be concluded that Cu plays a very important role in the normal reproductive physiology and its supplementation in a deficient diet is essential to obtain adequate reproductive performance in mature animals. |
