In the diet to fully meet the protein needs, especially with some rich in sulfur amino acids (methionine, cystine) protein, such as fish meal, silkworm cocoon, sterile cockroaches and so on. Plant protein is good for feeding sesame cakes, crispy cakes and sunflower cakes. If there is insufficient protein nutrition, the fur will appear sparse, and there will be “empty†phenomenon and reduce the quality of fur. Animal feed should account for 35% to 40%. Take 10 days before the skin, and incorporate some raw egg whites in the diet to increase the brightness of the plush.
Second, the diet should contain enough fat to not only facilitate the deposition of subcutaneous fat, but also improve the softness and luster of the skin. Feeding some high-temperature-processed rice pork can increase protein and fat, and the price is cheap. In mid-November, 10 grams to 15 grams of vegetable oil or animal oil can be added to the diet. It is best to add two kinds of oil alternately. In addition, the amount of corn fed can be increased. In addition to supplying the fox itself with energy needs, the remaining can be converted into body fat to accumulate. In order to increase the depth of plush, vitamin B2 3 mg to 5 mg and trace elements additives containing iron and copper can be added to the diet. The feed amount can be between 350 g and 400 g.
In addition to keeping the cage clean and dry in management, after entering the equinox, care should be taken to prevent tangling. Prevent fodder from splashing on foxes when feeding to avoid staining follicles. In the period of 2 to 3 months before skin removal, the fox can be raised in the shade or in areas with low light intensity to minimize the light, which can increase the gloss of the hair. Strong light is an important cause of hair color degradation.
At present, some fox households do not pay much attention to the use of foxes for the skin. There are crickets and crickets. The results are small in size, poor in quality, and low in economic efficiency. In the breeding period of foxes and winter hair growth period, animal feed accounts for 40% to 50% of the ration, and its first skin can reach 75%. The profit from the sale of fox fur will exceed the investment in raising the proportion of animal feed. Therefore, if you invest more in breeding, your profits will be higher.
Leather fox, also known as commodity fox, refers to young foxes that cannot be used for breeding and adult fox that are eliminated from foxes. These foxes are slaughtered and skinned during the maturation of furs. In order to obtain good quality fur, reasonable arrangements should be made in the daily food mix and management.
