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 supplem entation of vitamin E and source of dietary fat on serum enzymes durin g 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 die t of vitamin E or receiving fish oil had significantly lower alanine a minotransferase than those supplemented with 22 IU/kg diet of vitamin E. Differences in the enzyme activity between the treatment groups wer e small. Aspartate aminotransferase and creatine kinase were higher in gilts at farrowing than during either gestation or early lactation.
