Reproduction is the important productive parameter which affects the profitability of dairy industry. Micro minerals play an important role in animal’s reproductive physiology and its imbalance causes various problems leading to lowered reproductive efficiency. Therefore, adequate trace minerals supplementation and its absorption are required for various metabolic functions including reproduction and growth.
