Role of micronutrients in immunity and fertility of animal
Published:January 21, 2014
Summary
Introduction A number of micronutrients have been shown to affect various aspects of immunity in cattle. The interactions between nutritional status, immunology and disease resistance are extremely complex. Insufficient contents of micronutrients in animal diets have been related with low disease resistance and decreased disease resistance. A balanced supply of micronutrients, such as vi...
a worth reading and worth reference article. It must be read carefully by all those livestock farmers to whom breeding is more important than other traits of production
Mr Umesh has discussed the issue extensively
Excellent !! Short but more informative article. Mineral Nutrition is the most neglected part by the farmers. There is need to educate dairy farmers on this issue to regulate animals reproductive performance. This is one of the way to get one calf per year by regulating fertility and profitable business.
