Extract

Vitamin E functions as an antioxidant in animal tissues. Deficiency has been associated with sudden deaths in suckling and growing pigs as well as impaired immune function and reduced fertility. Of the tocopherols and tocotrienols present in nature, only a-tocopherol (a-T) appears in appreciable amounts in pig blood and tissues. A previous trial (Monahan et al., 1990) had shown that feeding a diet containing a high level of a-tocopherol to sows from day 3 of lactation resulted in a significant increase in sow plasma, sow milk and piglet plasma a-T levels. The present trial was designed to study the effect of feeding high a-T from late pregnancy or from farrowing on milk a-T levels.
