This trial was carried out to evaluate the nutritional value of early rice and late rice for growing Rex rabbits by digestion experiment. Eighteen healthy and white growing Rex rabbits at the age of 60 days with an average body weight (1.50±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 with basal diet, early rice diet (85% basal diet+15% early rice) and late rice diet (85% basal diet+15% late rice), respectively. Both pre-trial and formal trial periods lasted for 7 d. The apparent digestibility of main nutrients in early rice and late rice for growing Rex rabbits was measured by total feces collection method. The results showed as follows:1) 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 early rice were 16.25 MJ/kg, 86.32%, 7.82%, 1.32%, 8.54%, 23.35%, 10.54%, 1.54%, 3.58%, 0.53%, 0.38% and 64.76%, respectively, and those of late rice were 16.07 MJ/kg, 89.17%, 6.88%, 1.32%, 9.07%, 24.55%, 11.57%, 2.01%, 3.96%, 0.62%, 0.21% and 63.71%, respectively. 2) The apparent digestible energy and the apparent digestibility of GE, DM, CP, EE, CF, NDF, ADF, Ash, Ca, P and NFE of early rice for growing Rex rabbits were 10.43 MJ/kg, 65.33%, 74.32%, 76.69%, 68.59%, 13.12%, 38.63%, 27.11%, 52.23%, 50.03%, 15.54% and 74.35%, respectively, and those of late rice were 10.32 MJ/kg, 64.22%, 76.15%, 70.92%, 72.93%, 14.35%, 38.49%, 27.09%, 52.03%, 48.63%, 14.99% and 73.64%, respectively. In conclusion, the contents of major nutrients in early rice and late rice have no significant difference. Combined with the comprehensive analysis of two kinds of raw materials, the apparent digestibility of major nutrients in early rice and late rice for growing Rex rabbits are basically the same. Therefore, the nutritional value of early rice is close to late rice, and both of them can be used as the source of energy feed for growing Rex rabbits.
