Abstract:
Thirty anestrus Sahiwal cattle aged between 3.5- 4.5 years, were used to study the effect of Clomiphene citrate, Co-synch protocol and Mineral supplementation on estrus induction and fertility of cattle. Group 1, the animals (n=6) were fed ration containing 0% mineral mixture. Group 2, the animals (n=6) were fed ration containing clomiphene citrate (300mg). In Group 3, the animals (n=6) were subjected to co-synch protocol. Group 4, the animals (n=6) were fed ration containing mineral mixture 1% of ration and clomiphene citrate (300mg). In Group 5, the animals (n=6) were fed ration containing mineral mixture 1% of ration and subjected to co-synch protocol. The mean concentration of serum calcium, phosphorus, magnesium, copper, zinc, cobalt, selenium and iron from day 0, 21, 42, and 60 in Control group-1 and treatment groups-2, 3, 4 and 5 were recorded, where calcium, phosphorus, magnesium, selenium and iron differ significantly in days as well as in groups and zinc differ significantly in groups. Deficiencies of calcium, phosphorus, magnesium, zinc and selenium either singly or in combination could be responsible for anestrus condition in cattle and by improving the nutritional status the animal fertility can be improved. Therefore, in present study co-synch protocol along with mineral mixture improved the reproductive status of anestrus Sahiwal cows.
