Abstract

 The trial was carried out to evaluate the nutritive value of sunflower meal and peanut hull for growing rabbits. Eighteen growing rabbits at 110 days of age with an average weight of (2.34±0.16) kg were used in a completely randomized design, which consisted of 3 groups and 6 replicates in each group. A basal diet was formulated to meet requirements of growing rabbits and two other diets were formulated by substituting 20% of the basal diet with sunflower meal or peanut hull, respectively. Fecal apparent digestibility of major nutrients in sunflower meal and peanut hull for growing rabbits was measured. Both pre-trial and trial period was 5 days. It was observed that gross energy (GE), dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), ether extract (EE), ash, Ca, P and nitrogen free extract (NFE) contents of sunflower meal were 20.07 MJ/kg, 93.79%, 28.72%, 23.66%, 38.48%, 27.97%, 8.08%, 6.73%, 5.47%, 0.89%, 0.88% and 29.21%, and those above indexes of peanut hull were 17.34 MJ/kg, 93.11%, 8.68%, 50.91%, 63.28%, 55.33%, 21.08%, 1.66%, 9.16%, 0.53%, 0.10% and 22.69%. The apparent digestible energy of sunflower meal and peanut hull were (10.89±3.88) and (6.11±3.46) MJ/kg DM, respectively. Apparent digestibility of energy, DM, CP, CF, NDF, ADF, EE, ash, Ca, P and NFE in sunflower meal were 50.87%, 46.81%, 82.37%, 23.60%, 29.09%, 26.81%, 87.89%, 58.09%, 72.56%, 49.50% and 80.79%, and those above indexes in peanut hull were 32.82%, 28.89%, 81.54%, 23.20%, 28.62%, 26.20%, 87.72%, 58.16%, 72.73%, 49.39% and 81.12%, respectively. In conclusion, apparent digestibility of CP, EE, Ca and NFE in sunflower meal and peanut hull for growing rabbits were higher, while apparent digestibility of CF in sunflower meal and peanut hull for growing rabbits were lower, and the ADL was not able to be digested by growing rabbits.[Chinese Journal of Animal Nutrition, 2011, 23(10):1833 -1839]
