Effects of dietary vitamin E and fat on some serum enzymes in pigs

Forty-five gilts (15 groups of 3 gilts) were used to study the supplementation of vitamin E and source of dietary fat on serum enzymes during gestation and early lactation, as well as in piglets born from these gilts from birth to 28 d of age. Gilts supplemented with 88 IU/kg diet of vitamin E or receiving fish oil had significantly lower alanine aminotransferase than those supplemented with 22 IU/kg diet of vitamin E. Differences in the enzyme activity between the treatment groups were small. Aspartate aminotransferase and creatine kinase were higher in gilts at farrowing than during either gestation or early lactation.
