Abstract: The digestibility of main nutrient in 2 varieties of Italian Ryegrass for growing Fujian yellow rabbits was assessed by endogenous indicator method. The results show that: the digestibility of ryegrass "Maximus" and "Hercules" dry matter (DM), crude protein (CP), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude fat (EE), crude ash (ash), calcium (Ca), phosphorus (P) and nitrogen free extract (NFE) digestion rates was: 52.67%, 82.68%, 21.70%, 26.58%, 28.59%, 68.37%, 57.69%, 71.64%, 70.82%, 64.38% and 50.45%, 79.53%, 24.69%, 30.45%, 32.69%, 69.84%, 59.38%, 70.48%, 69.31%, 69.30%, respectively. The apparent digestibility of Italian ryegrass DM, CP, EE, Ca and P was high, and the apparent digestibility of CF was low.
