Extract

Colostrum and milk contain a number of important components such as immunoglobulins, fat soluble vitamins and essential fatty acids which have a marked influence on the health and welfare of the neonatal calf. The requirement of the neonatal calf for vitamin E is partly dependent on the dietary intake of polyunsaturated fatty acids (PUFA). Harris and Embree (1963) recommended that the ratio of vitamin E to linoleic acid (mg/g) should be between 1.5 to 2.5. Vitamin E is required to provide protection against peroxidative damage to the unsaturated fatty acids of plasma and membrane lipids and has been shown to play an important role in the development and maintenance of the immune system (Machlin and Bendich, 1987; Bendich, 1989). A study was conducted to examine the ratio of vit E to C18:2 in colostrum and milk and to investigate the effects of different dietary ratios of vit E to C18:2 erythrocyte membrane lipid composition.

Twelve Hereford x Friesian cows were used in this experiment. Seventeen calves born to these cows, five sets of twins and seven singles, were randomly allocated to four treatment groups as follows. Group A -untreated controls; groups B and C - supplemented with different levels of vitamin E; group D -supplemented with vitamin E and C18:2.
