Preparation of facilities
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 chamber has holes leading to the cage. If it is a round hole, the diameter is 10 cm. If it is a rectangular hole, it is 14 cm high and 12 cm wide. The chamber is closely connected with the cage. Food bowls and cups are made of medium-sized enamel or enamel cups. To prevent overturning when the leeches are active, they can be made of wire and placed on the cage door. When feeding, food bowls containing feeds are placed in the fixed card.
Preparation of feed
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.
