White raccoon dog and its characteristics
Raccoon dogs in nature have always been bluish brown, and this common color type is genetically called the wild type. In 1974, Harbin Zoo in Heilongjiang Province acquired a rare male white raccoon dog (eyes and kisses are light pink). In 1980, yellowish brown or light blue eyes and black white raccoon dogs or white raccoon dogs were found one after another in three northeastern provinces. These special color types, which are different from the wild type, are called mutants. The Special products Research Institute of Chinese Academy of Agricultural Sciences has successfully cultivated the existing new color type of white raccoon dog in China after nearly 10 years of research.
From the phenotypic point of view, the existing new color types of white raccoon dogs in China can be divided into two types: one is that the hairs and hairs of other parts of the body are white except the rims of the eyes, the margin of the ear, the tip of the nose, claws and the tip of the tail, and the other is that the hairs and hairs of all parts of the body are white. The coat colors of the two kinds of white raccoon dogs are lovable, their body shape is not significantly different from that of the common raccoon dogs, and their behavior is more tame than that of the common raccoon dogs.

Site selection and Construction of Fox Farm
Whether the location of the fox farm is reasonable or not directly affects the breeding benefit and the future production development. The purpose of site selection should be based on the natural environmental conditions suitable for the biological characteristics of foxes, and should be comprehensively considered according to the production scale and development vision. Focus on feed, water and epidemic prevention conditions, but also take into account the environment, temperature, light, transportation, electricity and other conditions. Therefore, before the construction of the site, we must carefully and comprehensively survey and rational layout according to the requirements of the overall planning, and it is best to choose barren land or non-cultivated land.
