Breeding leeches preparation

A, preparation of premises

Mink farms should be located in areas sheltered from wind, sun, and drying away from rabbit houses and sty houses, and facilities include sheds, cages, booths, food bowls, drinking glasses, catching nets, and fishing boxes. The role of the shelter is to shelter from the rain and prevent direct sunlight, so as to benefit the normal life of the group. The construction of the sheds can be made according to specific conditions or made into an easily constructed and compact shed. Water cages are required to be strong and durable, and they are mostly made of welded wire mesh or wire braid. A chamber that is 70 centimeters long, 50 centimeters wide, and 40 centimeters high, is similar in size to a cocoon cage. Most of them are made into water tanks and can also be made of bricks. The chambers have holes leading to the cage. If they are open, they have a diameter of 10 cm. If they are rectangular holes, they are 14 cm high and 12 cm wide. The chamber is closely connected with the cage. Food bowls and cups are made of enamel or enamel cups of moderate size. To prevent overturning when the leeches are active, they are often made of wire 8 and fixed in the door of the cage. When feeding, food bowls containing feed are placed in the fixed card. .

B, feed preparation

Mink feed includes animal feed, plant feed, vitamins and minerals. Animal feedstuffs include livestock and poultry meat, fish, dairy products, eggs, cocoons, and other small animals. Botanical feeds include cereals, beans, and fruit and vegetables. Vitamin feed often refers to cod liver oil, VE, VB, VC and so on. Mineral feed contains more bone meal and salt. The leeches require no more than 60% animal feed during the breeding season. Commodity breeding and animal husbandry in the non-reproductive period can be appropriately reduced, and plant feeds can be appropriately increased.

Dietary Formulation: In the mid-pregnancy period of the female parent, for example, the total amount of each diet is 300 grams, including about 30 grams of digestible protein. Diet formula: 15% of meat, 10% of milk eggs, 10% of cereals, 15% of vegetables, and 15% of water.
