- Abstract
The aim of the trial was to investigate the effect of using different levels of raccoon meat and bone meal in the diet on the application of the diet to male blue foxes during the breeding period. Ninety healthy male blue foxes of (30±5) days of age with an initial weight of (1.90±0.32) kg were selected randomly divided into six groups, test with one fox in each of replicate for a toted of 15 times. The control group (Group Ⅰ) was fed a basal diet and the test groups were fed diets supplemented with 3% (Group Ⅱ), 6% (Group Ⅲ), 9% (Group Ⅳ), 12% (Group Ⅴ) and 15% (Group Ⅵ) raccoon dogs meat and bone meal. Digestion and metabolism tests were carried out on days 55-57 of the test period, and blood was collected at the end of the test period to measure serum biochemical parameters. The results showed that: ① the final weight and average daily weight gain of group Ⅴ were significantly higher than those of groups Ⅰ, Ⅱ, Ⅲ and Ⅳ (P<0.05), and the feed-to-weight ratio was significantly lower than those of other groups (P<0.05). ② The digestibility of dry matter and crude protein of group Ⅳ was significantly lower than those of groups Ⅰ, and Ⅵ (P<0.05); the digestibility of crude fat of group Ⅴ was significantly higher than those of groups Ⅱ, Ⅲ, Ⅳ and Ⅵ (P<0.05). ③ Nitrogen intake and nitrogen deposition were significantly lower in all test groups than in group Ⅰ (P<0.05), net protein utilization was significantly higher in group Ⅵ than in groups Ⅱ, Ⅲ and Ⅳ (P<0.05), and the biological value of protein was significantly higher in group Ⅴ than in groups Ⅱ and Ⅲ (P<0.05). ④ Serum triglyceride levels were significantly lower in group Ⅴ than in group Ⅳ (P<0.05). Based on all the indexes, when the supplemental level of bone meal for raccoon dogs is 12%, breeding blue foxes achieve higher production performance.
