Do cows need vitamin E?
Vitamin E is important to help with selenium and vitamin A absorption, aids in immune function, and is an antioxidant important in cellular metabolism. Calves born to cows that are vitamin E-deficient can be born with white muscle disease, also a symptom of low selenium.
Which vitamin improves the fertility of livestock?
Recent interest in beta-carotene has been stimulated by reports that reproductive performance in cattle was improved with dietary supplementation of beta-carotene even when the diet was supplemented with vitamin A.
What are the symptoms of selenium deficiency in cattle?
