Comprehensive Introduction to Breeding Techniques for Colored Foxes and Colored Raccoon Dogs
Crossbreeding between the Vulpes genus and the Alopex genus Crossbreeding between the Vulpes genus and the Alopex genus has attracted increasing attention in fox pelt production and sales. This is mainly because the fur quality of the hybrid offspring is better than that of both parents; it overcomes the shortcomings of the silver fox's long and coarse guard hairs as well as the Arctic fox's short, fine guard hairs and easily matted underfur. The hybrid fox pelt has abundant underfur, even guard hairs, and vivid coloration, giving it higher commercial value. 1. Production of hybrid foxes The production of hybrid foxes is currently mostly carried out by means of artificial insemination

Comprehensive Prevention and Treatment Methods and Technical Points for Mange in Foxes and Raccoon Dogs
Mange is a chronic parasitic skin disease caused by mites of the families Sarcoptidae and Psoroptidae parasitizing the body surface or under the skin of fur-bearing animals. It is a contagious contact disease; if feeding and management are improper and treatment is not timely, it will directly affect animal health and fur quality, causing serious losses to farms. In recent years, with the increase in the number of foxes and raccoon dogs raised and the increase in density, the incidence of mange in foxes and raccoon dogs has also been rising, and some farms even frequently see cases of foxes and raccoon dogs dying from mange. 1 Pathogens Mites

Treatment Methods and Prevention Measures for Rotten Paw Disease in Raccoon Dogs
"Red paw disease" is actually vitamin C deficiency in newborn raccoon dog pups. Its manifestations: the limbs and toe pads of newborn pups become red and swollen, with ulceration, bleeding and erosion between the toes, appearing purplish-red; their suckling ability is weak, they constantly emit faint squeaking cries, and crawl about randomly in the den; some have thickened joints, and the tail becomes edematous and flushed, with the tail tip rotting off. It mainly harms pups within 10 days of age, and mostly occurs as whole-litter outbreaks; if not treated promptly, most die within 5 days. Treatment methods: normally, a complete-nutrition diet should be provided, especially for pregnant female raccoon dogs; daily

How to prevent and treat raccoon dog diseases? Detailed answers to thirteen questions
1. What causes a large number of raccoon dogs to have diarrhea? How to prevent and treat it? Answer: When a large number of raccoon dogs in a breeding group have diarrhea, the first thing to consider is the feed problem. Is the feed moldy and spoiled? Is the animal feed rotten? Has the grain feed been stored for too long? Is the salt content too high? Has the grain feed not been processed and cooked thoroughly enough? All of the above situations can cause a large number of raccoon dogs to have diarrhea. For prevention and treatment, the above problems must be solved. At the same time, feeding gentamicin, norfloxacin, chloramphenicol, oxytetracycline, sulfonamides and other drugs all have a certain

Fox and raccoon dog mange mite disease must be carefully guarded against in autumn and winter, never be overlooked
In the current season, the breeding of fur animals is entering the fur growth period. In addition to meeting the various nutrients required for fur growth, special attention should be paid to the occurrence of external parasitic diseases. Zhaoyuan Farm has 100,000 foxes and raccoon dogs in stock and has rich experience in the prevention and treatment of lice and mange mite disease. The precautions are introduced as follows: Pay attention to observation. Skin diseases such as lice and mange mite disease cause great harm to fur animal breeding. They should attract sufficient attention from the vast number of breeding farms and breeders. Especially in the current winter fur growth season, inspecting and preventing mange mite disease is work that breeders must not neglect before pelting.

4 Important Life Habits You Must Know for Raccoon Dog Farming
The raccoon dog's life habits have the following four characteristics. (1) Gregariousness: wild raccoon dogs usually live in pairs in dens, with 1 male and 1 female per den, though there are also cases of 1 male with multiple females or 1 female with multiple males. The parents and pups of neighboring dens usually play and frolic together, and mother raccoon dogs sometimes even nurse each other's young indiscriminately. Under domestic conditions, this characteristic can be used to group weaned pups into groups of 10~20 and raise them together in pens. (2) Nocturnal: this characteristic is very obvious in wild raccoon dogs. They sleep in their dens during the day and come out around dusk and dawn to move about and

Raccoon dog feed and nutrition, lecture 3: fats
In feed composition analysis, all substances that can be extracted with ether are collectively called crude fat, which includes fats, glycerol and lipoid compounds, etc. Fat is an essential component of the body. For example, the components of mitochondria and the Golgi apparatus in germ cells are mainly phospholipids, nerve tissue contains large amounts of lecithin and cephalin, and blood contains various fats. Skin and fur contain large amounts of neutral fats, phospholipids, cholesterol and waxes, etc. Fat is the main source of heat energy for the animal body and also the best form of energy storage. 1 gram of fat in the body

Breeding Methods and Key Technical Points for White Raccoon Dogs
White Raccoon Dogs and Their Characteristics. Raccoon 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 (with pale pink eyes and muzzle), and in 1980, white raccoon dogs or piebald raccoon dogs with yellowish-brown or pale blue eyes and black muzzles were successively found among domestic raccoon dog populations in the three provinces of Northeast China. These special color types, distinct 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 used these valuable white raccoon dog mutant genes

Causes and Prevention Methods of Stunted Raccoon Dogs
Stunted raccoon dogs refer to commercial raccoon dogs that cannot be raised to marketable size during the growing period after weaning and separation from the litter, showing no growth, small body size, being all skin and bones, and with messy fur, only reaching 2.5-3.5 kg by the growing period. Causes: There are many reasons for the formation of stunted raccoon dogs, generally as follows: unreasonable nutritional combination and incomplete nutritional value are the main causes of stunted raccoon dogs. Breeders try to save money and feed only cornmeal or with very little other feed. Because the feed is severely lacking in nutrition and cannot meet the growth needs of raccoon dogs, the raccoon dogs do not grow and become stunted.

What are the basic methods for diagnosing raccoon dog diseases?
Key points for attention in practical application. Reasonable combination of different protein feeds. Because different protein feeds differ in quality, mainly in essential amino acid content, when formulating dairy cow feed, the reasonable combination of protein feeds must be considered to ensure that dairy cows take in sufficient and appropriate protein nutrients. In actual production, when the feeds we use more of are corn meal, corn silage and DDGS, since these feeds contain more methionine and are relatively deficient in lysine, lysine becomes
