Breeding Methods and Technical Key Points for White Raccoon Dogs
I. White Raccoon Dogs and Their CharacteristicsRaccoon dogs in nature have always been dark brown; this common ordinary color type is genetically known as the wild type. In 1974, the Harbin Zoo in Heilongjiang Province acquired a rare male white raccoon dog (eyes and muzzle both pale pink). In 1980, among domesticated raccoon dog populations in the three northeastern provinces, white raccoon dogs or piebald raccoon dogs with yellow-brown or pale blue eyes and black muzzles were successively discovered. These special color types differing from the wild-type coat color are called mutant types. The Institute of Special Animal and Plant Sciences of the Chinese Academy of Agricultural Sciences

A Detailed Guide to Snake Breeding Habits and Artificial Incubation Methods
1. Snake breeding habits. Snakes are dioecious animals with internal fertilization, reproducing by laying eggs or by ovoviviparity. Their sexual organs mature 2 to 3 years after hatching. Male and female snakes are not obviously different in appearance; the easier way to distinguish them is that among snakes of the same species and similar size, the female generally has a smaller head and a shorter, plumper tail, while the male has a larger head and a thinner, longer tail. When the rear end of the cloacal opening is firmly pinched with two fingers, the female's cloacal opening appears flat and concave, while two "hemipenes," that is, a pair of copulatory organs, protrude from the male's cloacal opening. This is a simple and easy method for accurately identifying male and female snakes.
