The prospect of mink culture

1. Mink is a precious fur product: from the history of fur trade in the international market, mink has always been one of the pillar products. Raising precious fur animals at home and abroad is bound to form a mink-based situation and pattern.

2. The market prospect of mink: from the quality and value of mink, the utilization rate of mink is also higher than that of large capillaries such as fox and mink, especially in the domestic market. Mink is famous for its short plush, bright and luxurious. It is the main raw material for making clothes, collars, hats, cuffs and ornaments. It is widely used and in great demand. Because the fur is thicker and longer than mink and not as gorgeous as mink, the domestic market is not suitable for making coats, but only suitable for making collars, cuffs, shawls and other accessories, so the utilization rate is lower than mink. Thus it can be seen that the development prospect of small capillaries dominated by minks is better than that of large capillaries such as foxes and raccoons.

3. The market of mink is stable: the market order of mink is good, and the market has been more stable than fox and raccoon dog, and it has shown a steady upward trend in recent years. The law of high quality and high price embodied in the mink market not only greatly increases the price of colored mink skin, but also creates an opportunity for mink breeders to accelerate population improvement, produce marketable high-quality fur and improve economic benefits.

4. Great potential for development: at present, the amount of mink breeding in China is less than that of foxes, which shows the development potential of mink breeding. The number of domestic foxes, especially Arctic foxes, is higher than that of minks, which is driven by the short-term benefits of the current market. With the changes in the market of foxes and skins, the focus of breeding will definitely shift to minks in the near future, which will further enhance the development potential of mink farming.

Breeding conditions of mink

1. Feed conditions: minks are carnivorous animals. When choosing breeding feed, it should be noted that the animal feed of mink includes fish, meat and its by-product feed, dry animal feed, milk and eggs, etc. Mink plant feed includes cereals, cakes, fruit sparse, etc., and mink additive feed includes vitamins, antibiotics, antioxidants and inorganic salt feed.

2. Topographic conditions: mink farms should be built in places with high terrain and dry ground.

3. Water source and soil quality: mink farms require a lot of water due to processing feed, cleaning and washing, water recruitment, drinking, etc., so the site should be located near streams, rivers, lakes or ponds, or where there are rich and clean underground water sources.

4. traffic power supply: the mink farm should be built in a place where transportation conditions are more convenient. Only in this way can we ensure the timely transportation of feed and other substances. The power supply is an important source of energy for the mink farm. Feed processing, feed frozen storage, light-controlled mink raising in order to carry out all kinds of scientific research work in the mink farm, power supply is an indispensable condition.

5. Environmental hygiene: mink farms should be built away from livestock farms and poultry farms to prevent the transmission of homologous diseases. If an infectious disease of poultry or livestock has occurred in the area, it must be strictly disinfected and sterilized to meet the requirements of health and epidemic prevention before the site can be built. Mink farms should also keep a certain distance from residential areas to prevent human and animal activities from spreading epidemic diseases. The environment of mink farm needs to be secluded, so it is not suitable to be built near traffic roads and factories and mining areas with a lot of traffic.

6. Land conditions: the land area of mink farm should be spacious and open, which should adapt to the development plan of mink production in this field. However, we should try our best to avoid competing for land with crops and try to use barren land or idle land to build mink farms.

Construction of mink shed

1. Shed construction: shed is an equipment for minks to protect against cold and summer, which can be adapted to local conditions and local materials. The specification is generally 25 to 50 meters long, 3.5 to 4 meters wide, and 1.1 to 1.2 meters high. Some increase the span of single-family shed (about 8 meters), breed mink on both sides and raise mink in the middle, which can improve the utilization rate of single-family shed and improve the quality of fur to a certain extent.

2. Cage construction: it is a place for mink activities, feeding, excretion and breeding. The cage is made of barbed wire, and the cubicle is made of 1.5 centimeters and 2 centimeters of wood with various specifications.

① single-layer cage: the cage bar is 70 × 30 × 40 cubic centimeters (length × width × height). The chamber is 30 × 30 × 30 cubic centimeters or 45 × 35 × 45 cubic centimeters.

② double-layer cage: the lower layer is breed mink, the upper layer is leather mink or young mink. The species mink cage is 65 × 60 × 45 cubic centimeters, the small chamber is 45 × 40 × 40 cubic centimeters, the mink cage is 50 × 45 × 40 cubic centimeters, and the small chamber is 56 × 30 × 23 cubic centimeters.

There are many styles of mink cages, but they are simple and durable, do not affect their activities, do not run marten, meet the sanitary conditions, and are easy to manage and operate. The size of the mink cage depends on the mink used for different purposes.

Breeding and management of mink

1. Before mating: the main task of preparing the mating period is to promote the normal development of reproductive organs, adjust the suitable body condition, and ensure that the mink enters the mating period in time. For the convenience of feeding and management, the preparation and mating period of mink is usually divided into early stage (September-October), middle stage (November-December) and late stage (January-February).

2. Mating period: during the mating period, the appetite of minks decreased due to the influence of sexual activities, especially the male minks with strong breeding ability. Therefore, it is necessary to strengthen feeding and provide fresh, high-quality, nutritious, palatable and easy to digest diets. To ensure that the male mink has exuberant and lasting breeding ability and good semen quality.

3. Pregnancy: pregnancy is the key period for mink production. During this period, the metabolism of female mink is very exuberant, and the demand for feed and nutrients is more stringent than any other period. Because minks not only maintain their own life activities and hair change, but also provide nutrition for fetal growth and development, and reserve nutrients for postpartum lactation.

4. Litter lactation period: the quality of feeding and management in this period directly affects the lactation ability of female mink. Continuous lactation time and survival rate of young mink.

5. Maintenance period: after mating, the body condition of male mink generally decreases. In order to restore it as soon as possible, the feeding standard should not be reduced immediately. The feeding standard of pregnant female marten or male mink in the later stage of mating should be adopted. After 15 days and 20 days, the body condition of male mink has been recovered. And then transferred to the maintenance period. At the same time, the male mink should be concentrated away from the female mink to reduce the interference to the female mink. In addition, male minks with poor breeding ability, poor semen quality and loss of breeding value were eliminated.

6. Winter hair growth period: during this period, the metabolism level of minks is also higher, because minks not only store body fat and protein for overwintering, but also grow thick winter hair. Plush is the product of protein keratinization, so the need for protein, fat and some vitamins and trace elements is very urgent. Therefore, in order to produce high quality fur, the digestible protein in the diet should reach 30g / 35g and the metabolic energy should be 250 ~ 300kcal. Animal feed is 50% to 70%, which is mainly composed of fish, animal offal, blood, fishmeal, rabbits and poultry, etc. The total amount of diet is 350 to 400 grams.

7. Mink rearing: when the young mink is born, the living conditions have changed greatly, from the original gas exchange, nutrient intake and waste excretion through the placenta to breathing, feeding and excretion. After birth, the young mink is in direct contact with the external environment. Due to the imperfect development of the body, it is easy to die if it is not properly managed.

8. Young mink rearing: young minks have the ability to regulate body temperature and live independently after 40-45 days of age, and can be weaned when the ambient temperature is suitable. The development of young minks in the same litter is balanced and can be weaned once. They are reared in cages according to 3 minks of the same sex and divided into single cages after 7 days and 10 days. If the mink in the same litter has uneven development, the big, strong and strong feeding ability will be separated first, and the small and weak ones with poor feeding ability will continue to breastfeed for a period of time. Before separation, we should do a good job in the construction of cages, or inspection and repair of old cages, cleaning, disinfection and bedding of grass, do a good job of pedigree registration when dividing nests, and then provide high-quality, full-price, digestible and palatable feed after nesting, and provide mink with rapid growth and development after weaning in time, so it is necessary to ensure the supply of protein, minerals and vitamins.
