Abstract :

A

 total number of one hundred early weaning New Zealand white rabbits (EWNZWR) were used at 25 days of age with an average of 580.5 g. Rabbits were divided into 4 groups (25 rabbits each). Four substitution levels of sun dried Moringa oeliefera leaves (SDMOL) were used (zero%, 25%, 50% and 75%) instead of sunflower meal. Chemical analysis of Sun dried Moringa oliefera Leaves was higher in CP, NFE, EE, and ash than sunflower meal. Most nutrients digestibility were improved (P<0.05) with replacing sunflower meal by Sun dried Moringa  oliefera leaves at level 25, 50 or 75%. Also, using Sun-dried Moringa oliefera leaves in early weaning New Zealand white rabbits significantly (P<0.05) increased final body weight and daily body weight gain values. The tested diets have decreased significantly (P<0.05) meat content of DM (25.96, 25.80 and 24.86 vs 26.20), CP (20.74,20.89 and 21.02 vs 20.59) and EE (9.65,9.00,and8.73 vs10.15). Adding SDMOL to rabbit diets (P<0.05) decreased serum cholesterol and total lipids concentrate. Substitution of SDMOL improved the economic efficiency. It could be concluded that replacement up to 75% of sunflower meal in the early weaning New Zealand white rabbit’s diet by Sun dried Moringa oliefera leaves could be recommended to improve rabbit growth performance parameters, feed efficiency and carcass characteristics, meat content of DM, CP ,EE and decreased serum cholesterol, total lipids concentrates.
