Vitamin and water requirements of dairy sheep
The authors review the physiological role and the daily requirement of fat-soluble vitamins (A, D, E and K), vitamin C
and water in dairy sheep. Regarding the vitamins, classical clinical symptoms and/or non-specific parameters, such as
lowered production and reproduction rates are associated with their deficiencies or excesses. Until the last decade,
these compounds were considered important only for the prevention of such alterations; currently, there is more
emphasis on their function as the vitamins can play a key role in optimising animal health. In this respect, of particu-
lar interest is the action of the antioxidant vitamins (especially vitamin C, vitamin E and beta-carotene) in improving
the efficiency of the immune system.
