There are seven ways to improve the efficiency of raising mink.

First, choose a good breed of mink. The fur is bright, the color of back and abdomen is the same, the needle hair is short, the hair peak and hair are flat, the density is high, the distribution is uniform, the hair is soft, strong, the needle hair is slightly longer than the hair, and the sable has no white needle hair and white spot. This kind of mink fur is of good quality and high commodity value.

Second, do a good job in the feeding and management of the mating period. Minks breed once a year, estrus and mating from February to March every year. Therefore, the breeding male mink will enter the mating preparatory period in late January. During the breeding period, male minks should ensure the supply of high-quality concentrate feed, such as fresh blood, eggs, milk, liver, fish and other animal feed accounted for more than 80%, while increasing the drugs for nourishing yin and strengthening yang-Liuwei Dihuang pills, Herba Epimedii and vitamins e, b, c, etc. It is necessary to put an end to inbreeding and prevent the degradation of minks. Female mink in the late pregnancy, to ensure the supply of high-quality feed, slaughtered animals to feed, to remove the adrenal gland, pituitary and other organs containing sex hormones, so as not to cause stillbirth or abortion.

Third, pay attention to heat preservation to improve the survival rate of young minks. After birth, hot water bags should be placed on both sides of the litter box to keep warm, so as to improve the survival rate of young minks.

Fourth, prevent diseases. Generally speaking, in the period of the fastest growth and development of young minks (July and August), the temperature is high, the air humidity is high, the feed is easy to deteriorate, and the mink is very easy to be infected with digestive tract diseases. Fresh purslane, scented grass, plantain seed, purple flower, dandelion and other Chinese herbs should be collected and added to the feed. In this way, it can not only reduce the cost of feed, but also prevent heat and prevent enteritis, dysentery and other infectious diseases of digestive tract. Vaccines such as canine distemper, paratyphoid fever and Pasteurella multocida will be vaccinated in June and July to prevent infection. The vaccination site is on the inside of the posterior thigh.

Fifth, the use of substitute food. In order to reduce the cost, soybean powder and peanut cake can be used to replace part of the meat, sweet potato seedlings can be used instead of some vegetables, mixed with fresh pig blood, eggs and milk to enhance palatability.

Sixth, strengthen nutrition during the depilation period. The Autumn Equinox season, minks enter the hair changing period, this is the key period to improve fur quality, in addition to feeding high-quality concentrate feed, but also to add vegetable oil (soybean oil or peanut oil, etc.) and vitamin b2, 10 mg per mink per day.

7. Mature and take skin. Minks can be slaughtered and skinned after changing their hair. When you take the skin, take one when you mature, and never take the skin at once in batches. When slaughtering, we should pay attention to the integrity of the fur, do not cut the fur, otherwise the fur grade will be reduced.
