The aim of this review was to contribute to the knowledge of lipid requirements in dairy ewes, by reviewing experimental papers about lipid supplementation in dairy ewe feeding. The number of trials in ewe feeding is lower than that in dairy cow feeding and, leaving calcium soap of palm oil out of consideration, there is a lack of knowledge regarding the effects of protected and unprotected lipid sources on milk yield and quality from dairy ewes.

The general effect of calcium salt supplementation is an increase in milk unsaturated fatty acids and a decrease in saturated ones.

Abstract

The aim of this review was to contribute to the knowledge of lipid requirements in dairy ewes, by reviewing experimental papers about lipid supplementation in dairy ewe feeding. The number of trials in ewe feeding is lower than that in dairy cow feeding and, leaving calcium soap of palm oil out of consideration, there is a lack of knowledge regarding the effects of protected and unprotected lipid sources on milk yield and quality from dairy ewes. On the basis of data reported in the literature, the optimal dose of calcium soap of palm oil resulted to be 100-120 g/d. Also, milk fatty acid composition may be improved by adding calcium soap of fatty acids to ewe diets. The general effect of calcium salt supplementation is an increase in milk unsaturated fatty acids and a decrease in saturated ones. However, more research is needed in order to explain the effect of different fat sources (protected and unprotected) on milk yield and quality from dairy ewes
