The squirrel's fur has high economic value. In the past two years, as pets have been gradually domesticated, artificial breeding techniques are introduced as follows: I. Living habits Squirrels inhabit in temperate and sub-arctic coniferous forests and coniferous and broad-leaved mixed forests. In particular, it prefers pine trees dominated by pine needles and tall trees. Forests and shrubs that do not grow on short-stemmed trees. Almost living in trees, often using tree holes as nests. Also build their own nests, choose among the hidden branches, use twigs to build, and then pad with soft debris, such as birds feathers, animal hair, dead leaves, moss fresh and so on. It is also sometimes repaired using the old bird's nest. It generally has several nests, which are divided into main and deputy nests. The main nest is used for night-inhabiting and calving, while the deputy nest is temporarily inhabited. Male beasts generally do not nest. Often live alone, during the day, especially in the early morning. The squirrels do not hibernate in winter, but when the temperature is low, they rarely feed their nests and sleep in their hairy long tails. Its food includes pine nuts, acorns, chestnuts, various nuts, etc. It is commonly used to open nuts, eat insects, bird eggs and nestlings. There are stored food habits in the fall. When food is in short supply, they are forced to relocate. Squirrels are good at climbing, jumping, agile and lively, and have good visual and auditory abilities. Each year, 2 to 3 babies can be born, 35 to 40 days during pregnancy, 3 to 6 babies per child, and as many as 10 children. The newborn puppies were naked and naked, with red flesh and eyes closed. They grew some body hair in 14 days and blinked in 30 to 32 days. When the females left, they covered the pups with their nests. The pups started to leave the nest after 6 weeks. 8 to 9 months of sexual maturity. Its life span is 8-15 years and it has a record of 23 years. Second, the farmhouse construction and preparation Squirrels live alone in the wild, so the environmental conditions provided should allow them to have sufficient safari conditions, but also contact each other to facilitate reproduction. (a) The condition of the shed is an open three-walled structure, facing south to the south, with brick walls on three sides. The area is 5 meters long, 3 meters wide, and the room is 3 meters high. Sanhe soil surface, north of the door (1.8 meters high, 7 meters wide) through the corridor, but there should be a small partition outside the door, about 2 square meters, and then the side door to the corridor, mainly to prevent animals from running directly. The three-pronged nails on the room are lined with small wooden boxes and can be nailed to the first row more than 1 meter above the ground. The wooden box measures 25 centimeters long and 25 centimeters wide. It is open on one side (15 centimeters high and 12 centimeters wide) and the distance between the box and the box is 30 centimeters. The distance between the row and the row (the bottom of the bottom row and the bottom row of the bottom row) is 30 cm, and the two rows of wooden boxes can be staggered. Can be discharged to the top. After cultivation, the actual situation can be adjusted. In the middle of the room, put a large, dead tree or two or three medium-sized, dry plants for their activities. (b) The conditions of the stadium are directly connected to the open pens. The area is 36 meters long, 3 meters wide and 3 meters high. The three sides and the ceiling are all fine wire meshes, and the meshes should not exceed 1.5 cm. Under the net, 20 cm from the ground is surrounded by brick walls. Similarly, put 1 to 2 dry tree shrubs and triple land surface. III. Feeding Management and Breeding Techniques (1) The feed can be fed with pine nuts, hazelnuts, sunflower seeds, sunflowers, pears, apples, etc. According to seasons and different regions, as many feeds as possible are provided with them. Feed can be divided into several places so that they do not scramble. Dry materials can be added 1 to 2 days, and fruits are supplied daily. It is better to finish the day. The basin should always have clean water. (b) When the summer heat is managed, the performance of the animals can be observed. If necessary, temporary shades of mats or bamboo mats can be added to the ceiling of the stadium to cool the sprayed water. Winter does not need to take insulation measures. (3) Breeding technical points When introducing animals, it is necessary to choose a healthy body for breeding purposes. The ratio of male to female may be 3 to 4:1. Weak individuals, especially frail males, may be attacked by other males. During the breeding period, animal foods such as cooked eggs and bread can be given to see if they like it. In addition, put clean leaves, crushed ramie, twigs, etc. in the circle for their nests or nests. For a half-year-old pup, single-parent care should be allocated to avoid excessive density. Diseases and Natural Enemies Prevention and Control Since squirrels are under the conditions of captivity, they are not much noticed, and they are not easy to observe. Therefore, they have not reported any diseases. However, they belong to tooth carnivores and may transmit plague on the beam. Therefore, they must be properly sanitized every day and regularly disinfected. In addition, pens and sports grounds must prevent rodents and rats from drilling, causing feed rushing, harming squirrels, and spreading diseases.
