ABSTRACT Twenty four lactating Zaraibi goats in mid lactation were used in a 2 x 2 factorial experimental design to evaluate two different sources of ruminally degradable non structural carbohydrates (high and low RDNSC) and two different sources of ruminally degradable protein (high and low RDP). Four experimental diets were formulated to study their effects on digestion coefficients, some blood constituents and milk production and its composition. The obtained results indicated that digestibility coefficients for DM, OM, CP and NFE and the nutritive value in terms of TDN and DCP% were significantly (P
