How to identify the maturity of mink fur
The time for skin removal varies depending on the area and feeding management conditions, type, sex, age, and health status. Each farm should determine the best time for skin removal based on local climatic conditions and actual maturity. Mink skin maturation time is generally earlier than the standard, the old callus is younger than the younger, the female parent is older than the male, and the medium fat is healthier than the thin or sick one. The signs of mature fur: First, the whole body shacks off the net, the winter hair is changed, the hair is bright, the hair is thick and dense, and when the blisters bend, the visible "crack" can be seen. Secondly, the whole body has even peaks, especially the head and ears. The hairs are long and uniform, and the hair color is the same. There is no depression in the neck and back hair, the tail hair expands, and the tail is bulky and fluffy. Third, when peeling, the skin is easy to separate, the skin is white, or only the tip of the tail, the end of the limb has a gray, that is, mature fur. Fourth, blow the hair away to see the color of the living skin. In addition to white blisters, if the skin is pale pink, the skin itself is white, indicating that the pigment has been concentrated in plush, which is mature fur. If the skin is light blue, the skin itself contains melanin, which proves that the fur is not fully mature. The key to improving economic efficiency is to become familiar with the mature signs of mink fur and to obtain skin at the right time.
