Abstract

Ammonia concentrations were measured in the nests of farmed raccoon dogs (Nyctereutes-procyonoides Gray, 1834) and polecats (Mustela putorius) at weaning time. Ammonia levels in the nests of raccoon dogs and polecats varied from 1 to 43 ppm and from 0 to 5 ppm, respectively. In the raccoon dog, with increasing litter size, the ammonia concentrations tended to increase exponentially. In the polecat, no marked relationship between litter size and ammonia levels were found. The results show that no special adaptations are required in farm life because even the highest ammonia concentrations measured were below the harmful level.

摘要

在断奶期，对养殖貉（Nyctereutes procyonoides Gray，1834）和鸡貂（Mustela putorius）巢穴中的氨浓度进行了测量。貉和鸡貂巢穴中的氨水平分别在1至43 ppm和0至5 ppm之间变化。在貉中，随着窝仔数增加，氨浓度呈指数增长趋势。在鸡貂中，未发现窝仔数与氨水平之间有明显关系。结果表明，养殖环境中不需要特殊适应措施，因为即使测得的最高氨浓度也低于有害水平。
