The blue fox enters the litter and suckling period after the farrowing is completed. The time is from the fox of the mother fox to the litter of the fox, which is about 8 weeks. The central task of this period is to keep calving and promote the growth and development of the fox. Breast milk is the only food for the young fox. The growth and development of the fox for 3 weeks after birth depends entirely on the amount of lactation and the quality of breast milk. Therefore, the quality of breast milk directly affects the growth and development of the fox. During the pre-littering period, the nutritional level of the female fox should be enhanced to fully guarantee lactation and its nutritional needs. 1. Nutritional characteristics of litter and lactating Nutritional characteristics during lactation are to promote effective and sustained lactation of female foxes through nutritional regulation. The key to making the mother fox secreted milk is to ensure the various nutrients needed for lactation. Research shows that the content of dry matter in blue fox milk is 30.0%, protein is 14.5%, fat is 11.0%, sugar is 3.5%, and ash is 1%. Its protein and fat content is higher than that of mink milk, milk, and goat milk, and sugar is also Up to 3.5%. Therefore, lactation diets must provide sufficient protein, fat and carbohydrates to meet the needs of the female fox lactation. 2. Preparation of lactating diets The dietary nutrient level during the litter and lactation period should be maintained at the level of the gestation period. The type of animal feed should not be changed much. At the same time, animal feeds with high fat content such as broiler intestines and duck racks should be increased, and cornmeal should be appropriately increased. To meet its needs for fats and carbohydrates. According to the nursing standard of feeding 2720-2930 kilojoules of metabolic energy, 50-64 grams of protein, 17-21 grams of fat, and 40-48 grams of carbohydrates, the diet was prepared. The weight ratio of various feeds is: sea miscellaneous fish, eggs 45%-50%, chickens, ducks and other by-products 35%-40%, cereals 13%-14%. In addition, add a sufficient amount of various vitamins. Conventional feeding is generally fed 2 times a day, preferably 3 times. 3. Typical examples A large-scale 408 species of female foxes were fed and managed during the lactation period of a small fox farm: the mother fox was changed from the gestation period to the lactation period immediately after the farrowing was completed. As a result, the rearing rate of the fox was greatly improved, and the foxes were basically absent until the winter hair growth period. death.
