Vitamin E is important in the body for its anti-oxidant activity and a deficiency can lead to oxidative stress and immune suppression in peripartum cows. The fat soluble vitamin (which consists of a group of eight related compounds) is usually supplemented to dry cow diets to meet requirements. Differences in dry matter intake between cows in a herd may, however, lead to variation in the vitamin status of animals around parturition.

A recent article by Royal GD discusses the association between dietary intake and plasma concentrations of vitamin E in transition dairy cows. For this research, Schothorst Feed Research B.V. and Royal GD worked together to investigate how feed intake differences around parturition can influence the vitamin status of cows in the transition period.
