Milk yield and composition, feed efficiency, haemato-biochemical parameters and antioxidant status of lactating ewes fed diet supplemented with prickly pear cactus peels.

Prickly pear cactus peels (, PPCP) are a powerful source of antioxidant components and available as a by-product in arid regions in large quantities. The current work investigated the effect of dietary supplementation of PPCP on feed efficiency, milk yield and composition, haematology, serum biochemical constituents and antioxidant status of lactating Barki ewes. Fifteen multiparous female Barki sheep (2-3 years old, body weight post partum 46.
