Abstract

In this experiment, the digestibility of crude protein (CP) and effective energy values in 5 animal protein feeds were determined for raccoon dogs. A total of 60 raccoon dogs (30 males and 30 females) with similar body weight were selected and randomly divided into 6 groups, and each group contained 10 replicates (5 males and 5 females) with 1 raccoon dog as 1 replicate. The experimental diets were formulated with 15% (enzyme hydrolyzed feather meal or blood meal) or 20% (fish meal, meat and bone meal or chicken meat meal) of tested feeds replacing basal diet. The faces and urine were collected for 5 days after 7-day adaptation. The results showed that there were no significant differences between male and female raccoon dogs in the digestibility of dry matter, organic matter and CP, as well as digestible energy (DE) and metabolizable energy (ME) in all animal protein feeds (P>0.05). The DE and ME of fish meal, meat and bone meal, chicken meat meal, blood meal and enzyme hydrolyzed feather meal for raccoon dogs were 17.30 and 13.94 MJ/kg, 12.60 and 10.38 MJ/kg, 17.09 and 14.44 MJ/kg, 20.27 and 16.05 MJ/kg, 18.84 and 15.10 MJ/kg, respectively, and the apparent digestibility of CP in the above 5 ingredients were 94.8%, 80.7%, 81.0%, 92.6% and 87.5%, respectively. These results suggested that as the protein feed sources for raccoon dogs, fish meal has the highest CP digestibility, followed by blood meal and enzyme hydrolyzed feather meal, and chicken meat meal and meat and bone meal have the lower CP digestibility.

Key words： animal protein feed; crude protein digestibility; digestible energy; metabolizable energy; raccoon dogs
