Abstract

This trial was carried out to evaluate the nutritional values of soybean meal and sesame meal for growing Rex rabbits by feeding and digestion experiments. Eighteen healthy white growing Rex rabbits at the age of 60 days with an average body weight of (1.70±0.20) kg were randomly divided into 3 groups with 6 replicates per group and 1 rabbit per replicate. The rabbits in the 3 groups were fed a basal diet, a soybean meal diet (85% basal diet+15% soybean meal) and a sesame meal diet (85% basal diet+15% sesame meal), respectively. Both pre-trial and formal trial periods lasted for 7 days. The contents of gross energy (GE), dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), crude ash (Ash), calcium (Ca), phosphorus (P) and nitrogen free extract (NFE) of soybean meal and sesame meal were measured by chemical analysis method, and the apparent digestibility of above indices for growing Rex rabbits was measured by total feces collection method. The results showed as follows: the contents of GE, DM, CP, EE, CF, NDF, ADF, ADL, Ash, Ca, P and NFE of soybean meal were 17.34 MJ/kg, 88.43%, 45.00%, 1.89%, 7.38%, 13.15%, 7.97%, 0.77%, 6.36%, 0.33%, 0.59% and 27.80%, respectively, and those of sesame meal were 18.86 MJ/kg, 91.93%, 43.48%, 11.13%, 7.29%, 17.53%, 9.71%, 1.28%, 12.66%, 1.71%, 1.15% and 17.37%, respectively. The apparent digestibility of GE, DM, CP, EE, CF, NDF, ADF, ADL, Ash, Ca, P and NFE of soybean meal were 63.56%, 91.10%, 90.93%, 85.93%, 20.05%, 25.64%, 36.04%, -6.39%, 90.61%, 73.64%, 67.71% and 44.21%, respectively, and those of sesame meal were 62.05%, 46.96%, 64.75%, 51.23%, 17.25%, 33.90%, 18.44%, -8.05%, 54.11%, 52.88%, 47.17% and 16.14%, respectively. In conclusion, there are certain differences between the nutrient digestibility of soybean meal and sesame meal for growing Rex rabbits, and the nutritional value of soybean meal is better than that of sesame meal combined with the nutrient contents of feed ingredients.
