The experiment was conducted to study the effects of feed flavoring agents including the liver flavor, milk flavor, sweetener and bowel flavor on feed intake, nutrition digestibility, nitrogen metabolism and growth performance of growing male blue foxes. With the single factor designing, fifty health growing male blue foxes weighing approximately were collected and randomly allocated into five groups, each group containing ten replicates, and one fox per replicate. Foxes were fed the same basal powder diet supplemented with 0 (control group), 500 mg/kg liver flavor (group Ⅱ), 500 mg/kg milk flavor (group Ⅲ), 120 mg/kg sweetener (group Ⅳ) and 500 mg/kg (group Ⅴ) bowel flavor, respectively. The experiment lasted 52 d. The experimental results showed as follows: 1) compared with the group Ⅰ, the dry matter intake in groups Ⅱ and Ⅳ were extremely significantly increased (P<0.01), and the dry matter intake in group Ⅲ was significantly increased (P<0.05). 2) Compared with the group Ⅰ, dry matter output in group Ⅳ was significantly decreased (P<0.05), dry matter digestibility in groups Ⅱ, Ⅲ, Ⅳ and Ⅴ were increased by 4.34%, 9.07%, 9.40%, 5.23%, respectively, but the difference was not significant (P>0.05). Group Ⅳ showed a significantly higher fat digestibility (P<0.05). Groups Ⅲ Ⅳ and Ⅴ showed a significantly higher protein digestibility (P<0.01). 3) In the aspect of nitrogen metabolism, nitrogen intake, urine nitrogen and the protein biological value in experimental groups were no significant differences compared with the group Ⅰ (P>0.05); significantly lower fecal nitrogen and significantly higher nitrogen deposition and net protein utilization were observed in the group Ⅳ (P<0.05). 4) Body weight, the total weight gain and average daily gain were no significant difference among all groups (P>0.05). Average daily gain in group Ⅰ was the lowest, and that in groups Ⅱ, Ⅲ, Ⅳ and Ⅴ were higher 7.99%, 3.27%, 6.19%, 7.37%, respectively. Ratio of feed to gain from low to high were groups Ⅳ, Ⅲ, Ⅱ, Ⅴ and Ⅰ, respectively, but the difference were not significant (P>0.05). In conclusion, in this experiment conditions, the feeding flavoring agents of liver flavor, milk flavor sweetener can increase the dry matter intake and nutrition digestibility, and improve the feed utilization of growing blue foxes. The effect of sweetener is the best.
