Basic knowledge of mink breeding and common sense of ecological habits

A. site preparation:

mink farms should be located in windproof, sunny, dry places away from rabbit houses and pigpens, and the facilities include mink sheds, mink cages, chambers, food bowls, water cups, catches, mink boxes, etc. The function of the mink shed is to shelter from the wind and rain, prevent direct sunlight, and facilitate the normal life of minks. Mink sheds can be easily built into well structured sheds according to specific conditions

B. preparation of facilities:

mink cages are required to be strong and durable, and are mostly made of electric welding or wire weaving. Most of the chambers, which are 70 cm long, 50 cm wide and 40 cm high and similar in size to mink cages, are made of water tanks or bricks. The chamber has holes leading to the cage, such as round holes with a diameter of 10 cm, and rectangular holes with a height of 14 cm and a width of 12 cm. The chamber is closely connected with the mink cage. Food bowls and water cups are made of enamel or enamel cups of moderate size. In order to prevent minks from overturning when they are moving, they are often made of No. 8 iron wire and placed in the fixed card at the door of the mink cage. When feeding, put the food bowl containing feed in the fixed card

C. preparation of Technology:

the requirements of mink breeding technology are high. You need to self-study through books, newspapers and magazines in advance. You can also study in the "fox, mink and raccoon knowledge lecture" and the electronic journal "fox, mink and raccoon technology Anthology" of our school, so as to continuously improve and enrich the breeding technology

d, feed preparation:

mink feed includes animal feed, plant feed, vitamins and minerals. Animal feed includes livestock and poultry meat, fish, dairy products, eggs, silkworm chrysalis and other small animals. Plant feed includes Cereals, beans, fruits and vegetables. Vitamin feed often refers to cod liver oil, VE, VB, VC, etc. Mineral feed mainly refers to bone powder, salt, etc. Mink breeding period requires animal feed not less than 60%. Animal feed can be appropriately reduced and plant feed can be appropriately increased during the breeding period and non breeding period of commercial minks

e, the alumina recovery rate of epidemic prevention is 93.05%. Preparation:

foxes are prone to parasitic diseases to help ensure the accuracy of data. Canine plague, Aleutian disease, yellow fat disease, etc. should be carefully cleaned during feeding, and pay attention to the invasion of infectious diseases

f, preparation for introduction

before introduction, it is necessary to comprehensively and comprehensively understand the source of seed supply, master relevant knowledge, purchase from units with seed and seedling management qualifications, adhere to the principles of quality comparison, price comparison and service comparison, adhere to the principle of purchasing nearby, and ensure the quality, price and structure of mink breeding

II. Preliminary preparations for investing in mink projects

III. basic knowledge of mink feeding and management

a. feeding and management before breeding:

the central task of feeding and management during the preparation of breeding period is to promote the normal development of reproductive organs, adjust appropriate body conditions, and ensure that minks enter the breeding period in time. For the convenience of feeding and management, minks are usually divided into pre breeding (month), mid breeding (month) and late breeding (month). It is mainly to increase nutrition, improve fat and prepare for overwintering

b, breeding management during breeding period:

due to the influence of sexual activities, mink appetite has decreased during breeding period, especially male mink with strong breeding ability. Therefore, we should strengthen feeding and provide fresh, high-quality, nutritious, palatable and digestible diets. To ensure that the male mink has strong and lasting breeding ability and good semen quality

c, feeding and management during pregnancy:

pregnancy is the key period of mink production. During this period, the female mink's metabolism is very vigorous, and her demand for feed and nutrients is stricter than any other period. Because in addition to maintaining their own life activities and hair changing, minks also provide nutrition for fetal growth and development and reserve nutrition for lactation. Improve the technical level and utilization capacity of existing products

d, the effect of heavy metal elements being solidified in the soil and reducing their entry into crops during litter feeding:

the feeding and management of this period directly affects the lactation of Female Minks. Duration of lactation and survival rate of mink

E. breeding management of male minks after breeding:

after breeding, the body condition of male minks generally decreases. In order to recover as soon as possible, the breeding standard should not be reduced immediately. The breeding standard of Pregnant Female Minks or male minks at the later stage of breeding should be adopted. After days of recovery of the body condition of male minks, they should be transferred to the maintenance period

f, feeding and management of winter hair growth period:

the metabolism level of minks in this period is also high, because minks not only store body fat and body protein for overwintering, but also grow thick winter hair. Plush is the product of protein keratosis, so the need for protein, fat, some vitamins and trace elements is very urgent

g, mink rearing

mink birth: the living conditions have changed greatly, from gas exchange, nutrient intake and waste discharge through the placenta to self breathing, feeding and excretion. After birth, the mink is in direct contact with the external environment. Due to the incomplete development of the body, it is easy to die if the feeding management is improper

h, mink rearing:

at the age of days, minks have the ability to regulate body temperature and live independently, and can be weaned when the ambient temperature is appropriate. The mink in the same litter has a balanced development, and can be weaned once. They are only raised in cages according to the same sex, and divided into single cages after days. The development of minks in the same litter is uneven. First, those who are large and strong and have strong feeding ability should be separated, while those who are small and weak and have poor feeding ability should continue to breastfeed for a period of time. Before separation, the construction of the cage or the maintenance, cleaning, disinfection and grass bedding of the old cage should be done well, and the pedigree registration should be done well when the brood is divided. After the brood is divided, the high-quality, full price, digestible and palatable feed should be provided, and the water should be supplied in time. After the mink is weaned, its growth and development will be rapid, so it is necessary to ensure the supply of protein, minerals and vitamins
