In a feeding trial the proximate composition, acceptability, of either fresh or dry olive pulp and the effect of its inclusion in NewZeland white rabbits diets on growth performance parameters, some biochemical parameters and carcass traits were investigated. A total of 90, five weeks old, New Zeland while rabbits with an average weight of 650.5 ±20 gm were randomly assigned to five equal (each of 18 ) and were fed on five Isonitrogenus (% CP) and simi-isocaloric ( kcal ME-/kg) diets for seven weeks. The first group was served as control and fed on the basal diet while rabbits in groups 2 and 3 were fed on diets in which fresh olive pulp (FOP) were included at a rate of 5 and 10% of the diet respectively, and groups 4 and 5 were fed on in which dry olive pulp (DOP) were included at a rate of 2.5 and 5% of diets. Generally all diets proved to be acceptable and palatable dietary for New Zeland rabbits and promoted significant (P< 0.05) increase final live weight and improved feed conversion ratios (FCR) along the whole experiment as compared to the control group. Inclusion of either FOP and DOP at the aforementioned levels resulted in significant (P< 0.05) decrease in serum total lipids, cholesterol, triglycerides and glucose , however total serum protein, serum alanine amino transferase (ALT) , aspartate amino transferase (AST), creatinine, calcium and phosphorous levels did not significantly affect. On The other hand , carcass traits and Chemical composition of the rabbit carcasses concerning Dry matter (DM) , Crude protein ( CP), Ether extract (EE) and total ash % contents were also improved dietary treatments.
