Effect of different hormonal treatments on micro-minerals in post partum buffaloes

Forty-eight anestrus postpartum Murrah buffaloes were chosen randomly selected and divided into four groups with equal representation in each group. The buffaloes were treated with different progesterone implants and each buffalo received an intramuscular injection of 600 I.U. PMSG (Folligon) intramuscularly on the day when the device was removed. The concentration of copper increased non-significantly on day 3, 6 and 9 of treatment. However, the difference in the average concentration of serum levels Copper, Zinc and Iron within and were observed among the groups on the sampling days and found to be non-significant (P>0.05).
