Breeding of white raccoon dog

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 were found in families in three northeastern provinces. Kissing black white raccoon dogs or white raccoon dogs, these special color types 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 needles and villi of other parts of the body are white except the eye rim, ear margin, nose tip, claw and tail tip with the coat color of wild raccoon dog. The other is that the needle hairs and fluff 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.

Genetic characteristics of coat color of white raccoon dog

A large number of studies have shown that the genetic gene of raccoon dog white hair is dominant gene, and its corresponding wild type genetic gene is recessive gene, but raccoon dog white dominant gene has homozygous lethal effect, so all individuals of raccoon dog are heterozygote.

Selection and selection of white raccoon dog

At present, the coat color of the white raccoon dog type in China has been very stable, that is, the part of the white hair is white regardless of the needle hair and the villi are all white, and there is no other miscellaneous color (such as the needle hair is white and the villi is not white or part of the body is not white, etc.). Therefore, the selection of white raccoon dogs should focus on coat color, fur quality and body shape, especially male raccoon dogs.

The selection of white raccoon dogs should be mated with wild-type raccoon dogs, but not among white raccoon dogs. White raccoon dogs generally have the disadvantage of thick and long needle hair, and the selected wild raccoon dogs had better have short and dense needle hair to correct the shortcomings of white raccoon dogs.
