Extract

Many dietary oils have used in equine feeds primarily to improve joints and coat. Studies in rats have demonstrated the importance of dietary lipids in maintaining the normal discoid shape of the erythrocyte (Escadero et al., 1998). It is not yet known whether the addition of lipids to the diet can change the physiology of equine erythrocytes. The aim of this study was to identify the effects of sunflower oil (SF), green–lipped mussel oil (GLM), linseed oil (LN) and soya oil (SY) on erythrocyte shape and tendency to form rouleauxs in the horse.

Two New Forest ponies of similar age and weight and on clinical screening were used in the study. They were fed either the control diet (C) of silage ad libithum or the control diet plus 50ml of either SF, GLM, LN or SY. Bloods were taken prior to the start of dietary manipulation and at the end of the two–week experimental period.
