A Brief Talk on Raising Mink in North China

Marten belongs to the weasel family and predators. Its skin has many advantages, such as rich fluff, straight and warm, soft, bright and beautiful, noble dress and so on. It can process high-grade fine fur, and its products are very popular in western developed countries. At present, China's fur market is in a period of high price and market shortage, which is the industry with the highest benefit and the best market prospect in the aquaculture industry.

1 breed of mink

At present, the most famous breeds in the world are American mink and European mink. There are four species raised in the breeding grounds in Northeast China, such as Yinlan Shao, Mi Huangshao and red-eyed marten.

2 suitable growth conditions

The temperature in the northern region is long and cold in winter and mild and humid in summer, which is very suitable for Shao breeding, and the quality of its fur enjoys a high reputation in the world. Dongning County has built 30, 000 water SB farms, more than 95% of its products are sold to Russia and are developing to the Southeast Asian market. After five years of production practice, it has been proved that the development of mink breeding in the north is another shortcut to speed up farmers to get rich.

3 breeding grounds and equipment

The main purpose of mink breeding is to breed and produce fur. The site should be high, sunny, dry and leeward, away from noisy residential areas, main traffic roads, toilets and dung pits, so as to create a quiet, comfortable and hygienic living environment for minks. The cage box should be made of iron, generally 50-60 cm long, 30 cm high and 30 cm wide. the food trough and sink are fixed in front of the cage, and other appliances include capture boxes, meat hingers and so on.

(4) feeding and management techniques of mink

4.1 selection of mink species

The breed selection of mink is the key. The fine breed of mink produces good leather, large leather surface and good market price. For this reason, excellent varieties should be selected, such as large and strong body, early and fast hair change, fuller and fine fluff (coarse and shiny old marten hair), agile but not grumpy, sharp teeth and claws (on the contrary, Lao Shao), exuberant appetite, clear system, obvious stress response in parents and remote feeding of young marten.

4.2 Feed

Mainly fish, meat, animal water, food and fruits and vegetables. Excessive fat should be removed from meat and salted or dried fish should be soaked to remove salt. feed should be processed, crushed and steamed. Fruits and vegetables should be rooting, rotten, washed, and tuber feed cooked. Feed can be taken on the spot to reduce the feeding cost as much as possible.

4.3 Feed configuration

Shao's feed should be mainly animal feed (60% Mel 70%), supplemented by plant feed (30% Mel 40%), of which cereal feed (corn, bean cake, wheat bran, etc.) accounts for 15%, 20%, green feed (vegetables, fruits, etc.) accounts for 15%, 20%. The daily feed amount of each mink is 150-200 grams of animal feed and 50-100 grams of plant feed, and appropriate additives such as salt, bone meal, vitamin E and yeast tablets are provided.

4.4 main points of feeding and management at different growth stages

Pregnant mother Shao. The gestation period of female ferrets is about 47 days. Because the pregnancy period of female minks is relatively short, they should not only meet their own nutritional needs but also maintain the normal development of the fetus, so special attention should be paid to strengthening feeding management to ensure comprehensive nutrition and good feed quality. Eggs and fresh milk should be added in the third trimester (after 20 days). And to maintain a quiet and comfortable sanitary environment to prevent shock causing miscarriage.

Mother Shao and young mink during lactation. The breastfeeding period of young minks is 40-50 days, during which all mothers should strengthen their feeding and management. female minks should pay attention to adequate nutritional needs, and can be fed with broth (preferably pig's foot soup or chicken soup), eggs and fresh milk, vitamin B, vitamin E, bone meal and clean drinking water. The milk yield of the female mink decreased after 20 days, and the young mink should be given supplementary feeding at this time. Grind the fresh fish or meat, add egg yolk, vitamin B, vitamin E, bone meal, etc., and feed them once in the morning and afternoon, allowing them to feed freely until they are weaned. After weaning, the mother mink re-enters the mother mink pen, and the young mink after dividing the nest should pay attention to the temperature in the house to prevent the young mink from catching a cold after leaving the mother shao.

The young mink in the breeding period. After nesting, the young mink enters the breeding stage, which is also the normal stage of feeding and management. It takes about 130ml 150 days from birth to coming out of the column. In order to obtain better fur quality, it is necessary to strengthen the feeding management during this period. It can be divided into three feeding cycles, that is, 50-60 days after litter division, in this stage, Youshao grows rapidly, the amount of feed should be sufficient and full, and the supply of plant feed and fruits and vegetables can be increased in 61-90 days. however, a certain proportion must be ensured to prevent diarrhea. Entering the second growth peak in the first 130 days, it is also the stage of depilation and hair changing, which is the key period to obtain ideal fur quality. the supply of fish, meat, eggs and milk should be increased, and soybean milk and vegetable oil can be added to improve the fur quality. plant feed should not exceed 20%. Prevent fur scratches or hanging injuries, keep clean and hygienic, and ensure the quality of fur.
