Abstract

The objective of the study was to investigate the effects of bile acid level on the growth performance, nitrogen metabolism and serum biochemical indexes of raccoon dogs during the fur-growing period. A total of 64 male raccoon dogs aged 135 d were selected and randomly assigned to four groups with 16 repetitions in each group and 1 raccoon dog in each repetition. Animals in each group were fed diets with different levels of bile acid based:0 (group Ⅰ), 100 (group Ⅱ), 300 (group Ⅲ), 500 mg/kg (group Ⅳ). The pre-experimental and experimental periods lasted for 5 and 80 days, respectively. The growth performance, nitrogen metabolism and serum biochemical indexes of raccoon dogs were determined. The results showed as follows:the final weight, average daily gain and feed to gain ratio of raccoon dogs in group Ⅱ and group Ⅲ were significantly better than those in group Ⅰ (P<0.05); the ether extract digestibility and net protein utilization in group Ⅱ were significantly higher than those in group Ⅰ and group Ⅳ (P<0.05), and significant difference existed in serum total cholesterol content between group Ⅱ and group Ⅳ (P<0.05); serum triglyceride content in group Ⅳ was significantly higher than that in other groups (P<0.05); the liver index and renal index in group Ⅰ were significantly different from that in group Ⅱ and group Ⅳ (P<0.05), which were extremely significantly different from that in group Ⅲ (P<0.01); the spleen index in group Ⅰ was significantly different from that in group Ⅱ and group Ⅲ (P<0.05). In conclusion, under the condition of this experiment, the optimal level of bile acid is 100 to 300 mg/kg, and raccoon dogs during the fur-growing period has better growth performance.
