A Study On Hair Morphological Characters And Variety Of Artificial Breeding Arctic Fox (Alopexlagopus), Mink (Mustela Vison) In Winter

During October to December 2008, the research collected 7 furs of female Finnish arctic foxes (Alopex lagopus) from fur animal farm in Tuqiang of Mohe County,and noted their birth date and death date.8 pin-hair and 5 vellus were sampled from different parts of arctic fox including head, neck point A of back (the middle between neck and mid back), point B of back (the middle between mid back and hip), tail root and tail middle region. During September 12 to October 26, the research collected 7 furs of male Jinzhou black mink(Mustela vison) from the same farm. These male minks were born in 2008,and implanted exogenous melatonin (for short MT). During October 1 to November 26, the research collected 4 furs (3 adult and 1 young) of female Jinzhou black mink(Mustela vison). These female minks not implanted MT. 5 pin-hair and 5 vellus were sampled from different parts of mink including neck, back middle, tail root and tail middle region.All the sampled hairs were made into cuticular impression organic glass and medulla pattern slide. All the hairs were measured for indices including hair shaft length, hair root diameter, hair root length, hair diameter near hair root, medulla-absent region length near hair root, flat-shaped scale pattern length near hair root by using ruler, H6303i biological microscope and its supporting software for photoprocessing and measuring.Correlation analysis between these indices was conducted by using software SPSS 15.0, and proportion of swatches with medulla absent and flat/shaped scale pattern near hair root, was calculated.Results indicated:(1) These indices of pin-hair and vellus from arctic fox are correlated significantly.Pin-hair from mink, except hair shaft, other indices are correlated significantly. So,we can use one character of hair to know other character. (2) We can know whether arctic fox fur mature, by proportion of swatches with medulla absent near hair root of back. (3) Vellus finish growth earlier than pin-hair. (4) Hair from tail root and tail middle regions finish growth later than other regions.
