First, living habits
Squirrels inhabit temperate and sub-frigid coniferous forests and coniferous and broad-leaved mixed forests. In particular, they prefer pine forests that are dominated by pine needles and tall tree trunks, and forests and shrubs that do not grow in short-dry trees. Squirrels live almost in trees. They often use tree holes as nests, and they also build their own nests. They choose to nest among the hidden branches, use twigs, and then add soft debris such as bird feathers, animal hair, and 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 is a habit of storing food in the fall. When food is in short supply, they are forced to relocate. The squirrel is good at climbing and jumping. It has agile, lively and visual and auditory development. Twenty-three to three-children can be born each year, and 35 to 40 days during pregnancy. Each child has between 3 and 6 litters, and some as many as 10 babies. The newborn puppies were naked and naked, with red flesh and eyes closed. They grew some body hair in 14 days and blinked in the eyes for 30 days to 32 days. When the females left, they covered the pups with their nests. The pups started to leave their nests after 6 weeks and matured 8-9 months later. Lifespan is 8 to 15 years, and there are 23-year records.
Second, the construction and preparation of farm premises
Squirrels live alone in the wild, so the environmental conditions provided should allow them to have enough safari conditions and be able to contact each other to facilitate reproduction.
1. House conditions. It is an open three-walled structure, facing south to the south, with brick walls on three sides. The area is 5 meters long and 3 meters wide. 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 of the room are lined with small wooden boxes and the first row of nails can be started at a point 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 dead leaves for their activities.
2. Sports field conditions. Directly connected to the open sheds, the area is 36 meters long, 3 meters wide and 3 meters high. The three sides and the ceiling are surrounded by fine wire mesh, and the mesh hole 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 rakes and triple land surfaces.
Third, feeding and breeding and breeding technology
1. feed. Can feed pine nuts, sticks, seeds, sunflowers, pears, apples, etc., depending on the season and different regions, as much as possible to provide a variety of feed with their choice. The feed can be divided into several places so as not to compete for them. The dry material can be added once every 2 to 3 days, and the fruits are supplied daily. It is better to finish the day. The basin must have clean water at all times.
2. management. When the heat is hot in summer, 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 technology points. In the introduction of animals, the body must be selected for breeding as robust, the ratio of male to female can 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.
Half-year-old pups should be singled out to avoid excessive density.
Fourth, diseases and natural enemies
Because squirrels are not much in the conditions of captivity, they are not noticed and are not easy to observe, so there is no report of a certain disease. However, they belong to dental carnivores and may be infected with plague, so 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.
