MousaM.R.M. 5201155Olive pulp has high nutritive value and is available in large quantities in North Sinai. The present research was designed to study the effects of partial replacement of barley grains by olive pulp in the diets of growing rabbits on their performance. Forty eight weaned New Zealand White male rabbits (1160.62±19.7 g body weight) were divided into 4 similar groups. They were assigned to receive four treatments in which olive pulp (without nucleolus) replaced 0, 20, 25 or 30% barley grains. Their effects on nutritive values, growth performance and economical efficiency were studied during 56 days. Carcass traits and blood metabolites were determined by slaughtering 3 rabbits from each group at the end of the growth trial. The digestibility of organic matter, crude protein, crude fiber and nitrogen free extract significantly (p<0.05) decreased with increasing olive pulp level. Nutritive value of the diets in terms of digestible crude protein, total digestible nutrients and nitrogen balance were not significantly affected by olive pulp inclusion. Final body weight and daily weight gain along with carcass traits, carcass weight, dressing percentage, head and liver weights were not significantly (p<0.05) affected by olive pulp inclusion. Serum total protein, albumin, globulin, glucose, cholesterol, urea-N, Glutamic-oxaloacetic Transaminase (GOT) and Glutamic-pyruvic Transaminase (GPT) were insignificantly (p<0.05) affected with olive pulp inclusion. Rabbits fed diets containing olive pulp recorded lower feed costs to produce one kg gain. Accordingly, olive pulp without nucleolus could be used successively and safely in feeding growing rabbits up to 25% without adverse effects on performance and carcass traits.]]>Abd El-Galil, K.,200126727736Abd El-Naby, M.R.,19981998Abd El-Rahman, G.A., H.M., Abou El-Nasr, M.S., Ayyat, A.M.
