本试验旨在研究稻壳粉对生长肉兔生长性能、养分表观消化率和屠宰性能的影响。试验选择28日龄的体重相近的新西兰兔600只，随机分成5组，每组6个重复，每个重复20只，公母各占1/2。5组肉兔分别饲喂添加0（对照组）、5%、10%、15%和20%稻壳粉的试验饲粮。预试期7 d，正试期35 d。结果显示：饲粮中添加不同比例的稻壳粉对肉兔的平均日采食量无显著影响（P>0.05），但随着饲粮中稻壳粉添加量的增加，肉兔的平均日增重和死亡率呈下降趋势，料重比呈升高趋势。15%和20%稻壳粉组肉兔的平均日增重较对照组显著降低（P<0.05），料重比较对照组显著升高（P<0.05）。饲粮中添加不同比例的稻壳粉对粗脂肪、粗纤维、中性洗涤纤维、酸性洗涤纤维和酸性洗涤木质素的表观消化率无显著影响（P>0.05）。随着饲粮中稻壳粉添加量的增加，饲粮能量、粗蛋白质的表观消化率呈逐渐下降趋势，其中15%和20%稻壳粉组与对照组相比显著下降（P<0.05）。随着饲粮中稻壳粉添加量的增加，肉兔的屠宰性能呈下降趋势，其中20%稻壳粉组的全净膛重、半净膛重、全净膛率和半净膛率均显著低于对照组（P<0.05）。综合本试验测定指标，生长肉兔饲粮中稻壳粉的添加量不宜超过15%。

This experiment was conducted to study the effects of rice husk powder on growth performance, nutrient apparent digestibility and slaughter performance of growing meat rabbits. Six hundred New Zealand rabbits at 28 days of age and with similar body weight were randomly divided into 5 groups with 6 replicates per group, and 20 rabbits per replicate with half male and half female. Rabbits in the 5 groups were fed diets supplemented with 0 (control group), 5%, 10%, 15% and 20% rice husk powder, respectively. The pre-test period lasted for 7 days, and the experimental period lasted for 35 days. The results showed that diet with different addition amounts of rice husk powder had no significant effects on the average daily feed intake of rabbits (P>0.05), but the average daily gain and mortality of rabbits decreased with the increase of the rice husk powder addition amount, and the feed/gain increased. The average daily gain of rabbits in 15% and 20% rice husk powder group was significantly decreased (P<0.05), while the feed/gain was significantly increased compared with the control group (P<0.05). Diet with different addition amounts of rice husk powder had no significant effects on the apparent digestibility of ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF) and lignin (ADL) (P>0.05). The apparent digestibility of energy and crude protein (CP) showed a gradual downward trend with the increase of rice husk powder addition amount, and that in 15% and 20% rice husk powder groups was significantly decreased compared with the control group (P<0.05). With the increase of rice husk powder addition amount, the slaughter performance of rabbits showed a downward trend, and the half carcass weight, full carcass weight, half eviscerated rate and full eviscerated rate in 20% rice husk powder group was significantly lower than those in the control group (P<0.05). According to the test indexes of experiment, the addition amount of rice husk powder in the diet of growing meat rabbits should be not more than 15%.
