abstract
The study was conducted to observe the impact of lactation on serum trace minerals in Pandharpuri buffaloes maintained at college farm of KNP College of Veterinary Science, Shirwal. The animals were categorized in Group 1(Lactating) and Group 2 (Non-lactating) comprising 8 (eight) animals in each group. Trace minerals (Fe, Cu and Zn) were analyzed by using AAS. The present data reveals that there was significant effect of lactation on the levels of serum zinc with lower value in lactating than non-lactating Pandharpuri buffaloes. However, there was no significant effect of lactation on the levels of serum iron and copper values in these groups. The value of iron was non significantly higher and the value of copper was non significantly lower in nonlactating than lactating Pandharpuri buffaloes. All trace minerals studied in blood serum of lactating and non-lactating Pandharpuri buffaloes were within physiological limits.
