1, living habits Weasel mammals, timid, lived up and down, quick action. Mainly live in forests, farmland firewood. Staple rats, fish, frogs, crickets, birds, insects, and livestock and poultry.
2, feeding methods
(1) Outdoor enclosures. A 20-square-meter farm is built, with brick or stone bases up to 2 meters or more, and the wall is plastered with concrete. Trees are planted outside the walls to create a good and quiet environment. Stones, waste bricks, and mud are piled up on the field to form hillocks and caverns. The depth is 50 cm and the height is 25 cm. The number of caves should be more than 1/4 of the number of breeding animals.
(2) care (room) raising. That is, they are kept in brick houses or wooden houses. The breeding room should be tight and solid, laying the ground with cement to prevent escape. Place a partition on the top and place the nest box. The nest box is 20 to 30 centimeters in height, each 40 centimeters long and wide, and two holes with diameters of 7 to 8 centimeters are opened to facilitate free activities.
(3) cage care. The cage is made of wire cages and nest boxes. The wire cage is a place for eating and activities. It is 80 centimeters long, 70 centimeters wide, and 40 centimeters high. The frame is welded with steel or angle iron, and the outer wire mesh is 1 to 2 centimeters in diameter. The upper door is set for feeding and cleaning, leaving a small hole at the bottom of the side to communicate with the nest box.
3, feed compound feed mainly to meat, properly add cereals and vegetables. Non-propagation feed formula: meat 30%, fish and shrimp 10%, animal viscera 15%, soybean cake 10%, bran 20%, radish 10%, cabbage 5%. Add 2 grams of salt, 5 grams of bone meal, 5 grams of yeast, and 1 gram of cod liver oil per 500 grams of mixed feed. During the breeding period, meat feed can be increased to about 75%.
4, reproduction of technical maturity is generally about 10 months of age, every year from the beginning of March to the end of April is the estrus mating period. The estrus manifested itself as excitement, frequent activities, decreased appetite, and often screaming. The genitalia was slightly swollen at the beginning of estrus. The surrounding area was still concealed by the hairy plexus. Later, the external genitalia was obviously swollen and valgus, and the pubic hair fell to the lower part of the tail. Mating usually takes about 1 hour. The gestation period is 30 to 40 days, and the baby is born late in the spring and early summer. There are 5 to 8 litters per birth and the useful life is 3 to 4 years. The weasel's motherhood is very strong, and 4 to 5 days before the onset of labor, the grass nest nest, litter process about 20 to 30 minutes. The pups eat for about 20 days and they are weaned about 40 days later.
5. Feeding and management Each day feeds once in the morning and evening. It feeds 40% of the diet at 7 to 8 in the morning and 60% at 5 to 6 in the afternoon to stop appetite once a week. On a daily basis, 150-200 grams of male rats and 130-180 grams of mother rats were fed. Thoroughly clean the cages before feeding each evening, change the bedding, brush the utensils, and make up the water. Do summer heat, moisture, and disease prevention. Keep the environment quiet during pregnancy to prevent miscarriage due to startle. The weasel has the best period of fur quality from the Osmia to the beginning of spring, with fine coats and full hairiness. High temperatures in summer and autumn, rough and sparse, poor quality.
