银黑狐和北美赤狐毛绒品质的差异分析OA

To compare the fur quality of silver foxes(Vulpes vulpes fulva)with red foxes(Vulpes vulpes),a total of 120 healthy,9-month-old foxes(60 silver foxes and 60 red foxes,with equal numbers of males and females)were selected.The pelt length,the lengths of guard hairs and underfur,the fineness of guard hairs and underfur were measured.The ratio of guard hairs length to underfur length and the coat density were calculated.The correlations among these indicators were analyzed.The results showed that the underfur length of silver foxes,guard hairs length of female silver foxes and pelt length of female silver foxes were significantly longer than those of red foxes(P<0.01). The pelt length of male silver foxes was also significantly longer than that of red foxes (P<0.05). The underfur fineness and coat density of silver foxes were significantly lower than those of red foxes (P<0.01). Correlation analysis revealed significant relationships among guard hairs length,underfur length,guard hairs fineness,and underfur fineness (P<0.05),no significant correlation was found between coat density and pelt length (P>0.05). It demonstrated that silver foxes were significantly better than red foxes in terms of guard hairs length,underfur length and pelt length,but had finer underfur and lower coat density. There was a significant correlation among the fur traits. The results of this study provided a scientific basis for the selection of high-quality fur.
