本试验旨在研究饲粮中添加艾叶粉对生长肉兔营养物质表观消化率、氮代谢和肌肉品质的影响。试验选取160只35日龄的体重相近的商品伊拉肉兔，随机分成4组（每组40个重复，每个重复1只兔），分别饲喂艾叶粉添加量为0（对照组）、3%（替代对照组饲粮中1%的花生秧和2%的小麦麸）、6%（替代对照组饲粮中3%的花生秧和3%的小麦麸）、9%（替代对照组饲粮中4%的花生秧和5%的小麦麸）的饲粮。预试期7 d，正试期30 d。结果表明：饲粮中添加3%、6%和9%的艾叶粉对粗纤维（CF）、中性洗涤纤维（NDF）、酸性洗涤纤维（ADF）、木质素（ADL）、钙（Ca）、磷（P）的表观消化率以及食入氮、粪氮、尿氮、沉积氮、氮利用率、氮生物学效价均无显著影响（P>0.05）；饲粮中添加3%和6%的艾叶粉对家兔饲粮的CP的表观消化率和可消化氮无显著影响（P>0.05），但饲粮中添加9%的艾叶粉显著降低了饲粮的CP的表观消化率和可消化氮（P<0.05）；与对照组相比，饲粮中添加6%和9%的艾叶粉显著提高了饲粮中粗脂肪（EE）的表观消化率（P<0.05）；与对照组相比，饲粮中添加3%、6%和9%的艾叶粉显著增加了肌肉的滴水损失（P<0.05），而对其他肌肉品质指标并无显著影响（P>0.05）。综合本试验测定指标，生长肉兔饲粮中艾叶粉的添加量不宜超过6%。

This experiment was conducted to study the effects of dietary Artemisia argyi powder on apparent digestibility of nutrients, nitrogen metabolism and muscle quality of growing meat rabbits. One hundred and sixty Hyla meat rabbits at 35 days of age and with similar body weight were randomly assigned to 4 groups with 40 replicates per group and one rabbit per replicate. Rabbits in the 4 groups were fed diets added with 0 (control group), 3% (1% peanut vine and 2% wheat bran in the diet of control group were replaced), 6% (3% peanut vine and 3% wheat bran in the diet of control group were replaced) and 9% (4% peanut vine and 5% wheat bran in the diet of control group were replaced) Artemisia argyi powder, respectively. The pre-test period lasted for 7 days, and the experimental period lasted for 30 days. The results showed that diet added with 3%, 6% and 9% Artemisia argyi powder did not significantly affect the apparent digestibility of crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), calcium (Ca) and phosphorus (P) (P>0.05), and the intake nitrogen, fecal nitrogen, urine nitrogen, retention nitrogen, nitrogen utilization and biological value of nitrogen were not significantly affected by diet added with 3%, 6% and 9% Artemisia argyi powder (P>0.05). The apparent digestibility of crude protein (CP) and digestible nitrogen had no significant effects when diet added with 3% and 6% Artemisia argyi powder, but diet added with 9% Artemisia argyi powder significantly reduced the apparent digestibility of CP and digestible nitrogen (P0.05), compared with the control group. According to the test indexes of this experiment, the addition of Artemisia argyi powder in the diet of growing meat rabbits should be no more than 6%.
