| Abstract: | The incidence of trichophagy in five varieties of minks (jinzhou-black mink,coffee mink,silver blue mink,Red-eye white mink and American shorts mink) was counted in Dalian mink nursery.The incidence rate of different varieties,sex,and age implanted of exogenous melatonin or not were calculated and analyzed,respectively to explore the causes and relative factors of mink trichophagy.The results showed that variety difference significantly affected the incidence rate of trichophagy (P<0.05) in these 5 kinds of minks,with the highest incidence rate of 12.61% occurred in coffee mink;sex also greatly affected the happen of disease,female mink’s incidence was obviously higher than that of the male mink (P<0.05);the age had no significant influence on the incidence (P>0.05);the while,exogenous melatonin implanting could significantly (P<0.05) reduce the incidence rate of trichophagy. |
