本试验探讨了不同粗蛋白质（CP）和赖氨酸（Lys）水平颗粒饲料对生长期乌苏里貉生长性能的影响。试验选用72只仔貉进行3［CP：18%（P1）、21%（P2）和24%（P3）］×3［Lys：1.6%（L1）、1.8%（L2）和2.0%（L3）］双因子交叉饲养试验，共分为9个处理，每个处理8个重复，每个重复1只貉。试验期14周。结果表明：在第8周和第12周时，P3水平的平均体重显著高于P1水平（P<0.05）。在第14周时，P3水平的平均体重显著高于P2水平（P<0.05），极显著高于P1水平（P<0.01）。P3水平的总增重显著高于P2水平（P<0.05），极显著高于P1水平（P<0.01）。第12周和第14周时，P2、P3水平的平均体长显著大于P1水平（P<0.05），且P2、P3水平间差异不显著（P>0.05）。Lys水平在整个试验期内对平均体重、总增重、平均体长、总增体长均无显著影响（P>0.05）。由此得出，以体重为主要衡量指标，生长期乌苏里貉颗粒饲料中CP水平为24%最理想；以体长为主要衡量指标，CP水平达到21%～24%较理想；Lys水平达到1.6%即可满足生长期乌苏里貉的Lys需求。

In this study, the effects of pellet diets with different levels of crude protein (CP) and lysine (Lys) on growth performance of Wusuli racoon dogs during the growing period were investigated. A 3 ［CP: 18% (P1), 21% (P2) and 24% (P3)］×3 ［Lys: 1.6% (L1), 1.8% (L2) and 2.0% (L3)］ design of two-factor cross-over feeding trial was conducted on 72 young racoon dogs which were divided into 9 treatments with 9 replicates in each treatment and 1 racoon dog per replicate. The trial lasted for 14 weeks. The results showed as follows: at week 8 and week 12, the average body weight of P3 level was significantly higher than that of P1 level (P<0.05). At week 14, the average body weight of P3 level was significantly higher than that of P2 (P<0.05) and P1 levels (P<0.01). The total gain weight of P3 level was significantly higher than that of P2 (P<0.05) and P1 levels (P<0.01). At week 12 and week 14, the average body length of P2 and P3 levels was significantly higher than that of P1 level (P<0.05). No significant difference of average body length was found between P2 and P3 levels (P>0.05). The average body weight, total weight gain, average body length and total increase of body length were not significantly affected by Lys levels during the whole trial period (P>0.05). In conclusion, for the growing period of Wusuli racoon dogs, the optimal level of diet CP is 24% when considering body weight as main target; the better levels of diet CP are 21%～24% when considering body length as main target; 1.6% Lys in diets can meet the Lys requirement of Wusuli racoon dogs during the growing period.［Chinese Journal of Animal Nutrition, 2010，22（5）:1407-1412］
