Diagnosis and Treatment of Clostridium perfringens Infection in Raccoon Dogs
In August 2003, raccoon dogs raised by an individual farmer were infected with a disease characterized by fever, diarrhea, respiratory difficulty, and acute death. Through epidemiological investigation, clinical examination, pathological necropsy, bacteriological examination, and serotyping, the disease was confirmed as Clostridium perfringens infection in raccoon dogs. 1 Outbreak information: An individual farmer raised 64 raccoon dogs, 8 became ill, and 4 died, with a morbidity rate of 12.5% and a mortality rate of 50%. 2 Clinical symptoms: The onset was acute, with sudden death without any clinical symptoms, and the course of disease

What are the sanitation requirements for raising Ussuri raccoon dogs?
General sanitation requirements 1. A lime disinfection trough made of cement must be set up at the entrance of the raccoon dog farm; if conditions permit, sunlight disinfection can be added, as ultraviolet rays have a very good killing effect on anthrax spores and Pasteurella. All personnel should enter and exit through this point, and outside visitors should be controlled. Feeding and technical staff should manage their respective raccoon dog groups, tools, feeding utensils and supplies according to their division of labor, and must not mix them up. 2. The ground of the raccoon dog farm should always be kept clean and dry. Quicklime powder should be spread on the ground of the pens once a week, and feces should be cleaned up once a day and concentrated in a fixed location

Analysis of Issues in the Formulation and Use of Complete Feed for Ussuri Raccoon Dogs
The raccoon dog is an animal endemic to East Asia, mainly found in China, Russia, Korea, Japan, Mongolia and other countries, and is divided into many subspecies. The Ussuri raccoon dog is mainly distributed in China's Heilongjiang Province, the eastern and southeastern regions of Jilin Province, and northeastern Korea. At present, the vast majority of raccoon dogs bred in captivity in China are Ussuri raccoon dogs originating from Heilongjiang Province. The raccoon dog is one of the fur-bearing animals with high economic value. Compared with foxes and mink, it has the advantages of bearing more cubs, a high survival rate, being easy to raise, and having a stable market; therefore, in recent years the number of raccoon dogs raised in China has steadily increased year by year, with good momentum

A Detailed Guide to Practical Methods for Identifying Estrus in Foxes, Raccoon Dogs and Mink
I. Estrus identification in foxes: For the fox estrus period, the silver fox (silver-black fox) is generally from mid-January to mid-March; the Arctic fox (blue fox) is from mid-February to late April. Estrus in male foxes is easy to determine. A male fox entering estrus is active, drawn toward the opposite sex, has reduced feed intake, urinates frequently, and the "fox scent" in its urine becomes stronger. When a female fox is placed with it, the male shows great interest, continually mounting the female, and if the female is in estrus, mating is successfully achieved. Estrus identification in female foxes is relatively complicated; commonly used identification methods include the vulva observation method, the pair-pen teasing method,

What causes raccoon dogs to get smaller and smaller as they grow
(1) Breed degeneration: breed degeneration lowers production performance, which leads to raccoon dogs only eating without gaining meat. (2) Severe selenium deficiency: selenium deficiency causes white muscle disease in animals, with muscle atrophy and gradual emaciation, what farmers call "raccoon dog emaciation" (3) Parasitic infection: eperythrozoonosis and other diseases also produce this symptom. For treatment, use sodium selenite vitamin E injection. Intramuscular injection or mixing sodium selenite powder into feed; recovery takes a relatively long time. During the rearing process, trace elements and various nutrients should be supplemented by feeding a complete feed.

Detailed Explanation of Treatment Techniques and Methods for Raccoon Dog Diseases
(1) Restraint methods for raccoon dogs. For manual restraint, hold a wooden stick in one hand and wave it in front of the raccoon dog's eyes to distract its attention, while the other hand seizes the opportunity to quickly grab the tail and lift it from the cage, clamping the neck under the armpit, or securing it on the ground or on an operating table. If a capture board, capture tongs, capture net, or capture snare is available, it can be used to clamp the raccoon dog's neck or enclose its entire body, and with the assistance of a helper, diagnosis and treatment can be carried out. Pharmacological restraint can also be used, namely diluting chloral hydrate with a 2% starch solution into a 10% solution for enema administration to the raccoon dog.

Detailed Explanation of Key Points for the Prevention and Control of Mink and Raccoon Dog Diseases
This disease is an acute, highly contagious infectious disease caused by a virus. The main characteristics of this disease are severe diarrhea, with grayish-white sloughed intestinal mucosa and fibrin mucous masses in the feces, a significant decrease in white blood cells, and severe gastrointestinal inflammatory changes. 1. Pathogen The pathogen of this disease is raccoon dog enteritis virus, which has the main characteristics of the parvovirus group. From the perspective of the virus, raccoon dog enteritis virus is related to feline panleukopenia virus, and the vaccines prepared from each can provide cross-protection to each other; however, protection against canine parvovirus enteritis is poor. 2. Epidemiological characteristics

Questions and Answers on Building a Raccoon Dog Farm and Introducing Breeding Stock
Q: What are the prospects for raccoon dog farming? Can it make money? A: The prospects for raccoon dog farming are promising, and it can make money. Q: Which regions are suitable for developing raccoon dog farming? A: The raccoon dog's place of origin is in the northern regions of our country, and it can be raised in any area north of 30°N latitude. The quality of raccoon dog pelts produced in higher-latitude regions is superior to that of pelts from lower-latitude regions (30°--40°). To ensure pelt quality, breeding stock should be introduced from high-latitude regions (north of 40°) as much as possible, and preferably a portion of new breeding stock should be introduced every year to renew the bloodline and improve

A Detailed Guide to the Processing and Preparation Methods of Raccoon Dog Feed
The feed of raccoon dogs includes animal-based feed, plant-based feed and supplementary feed. The supply and composition of feed have a great influence on the health, reproduction and fur quality of raccoon dogs. To practice scientific raccoon dog farming, one must understand the effects of the nutrients in feed on raccoon dogs, so as to reasonably and correctly formulate and process feed, and obtain the best economic benefits with the least feed consumption. Therefore, the processing and preparation of feed is very important. I. Feed Processing (1) Processing of fish and meat feed Fresh marine mixed fish, and the meat, liver,

Processing Methods and Technical Key Points for Fox, Raccoon Dog and Mink Feed
Fur-bearing animals such as mink and foxes have well-developed canine teeth, a short digestive tract, a small stomach volume and no cecum, food passes through the digestive tract quickly, and their digestive glands secrete little amylase but more lipase. Therefore, their feed should be based mainly on animal feed, and in particular animal protein feed should account for a very large proportion of the daily ration. Thus, the feed processing and preparation methods for mink and foxes have distinctive characteristics, which are introduced below: 1. Material selection. Remove large pieces of fat from meat feed, remove the gallbladder and thyroid from livestock and poultry offal, and pick out lumps, impurities or foreign matter from dry animal powder feed and grain powder.
