Raise foxes in the yard to find a way to get rich.

Zou Benman, a big grain grower in Nanshantun, Changxing Island Town, introduced 11 northeast silver foxes using 500 square meters of open space behind the house in 2003. In 2004, the population was expanded to 62, and now 80 young foxes have been bred. Because Zou Ben is full of technical management and knows how to raise and manage, he pays attention to study and observation in the process of breeding and management of foxes and young foxes, and has mastered a set of techniques of disinfection, immunity, epidemic disease prevention and artificial fertilization, which improves the birth rate of foxes and the survival rate of young foxes. At the end of 2004, excluding the feed cost, the net profit was nearly 20,000 yuan. Zou Benman's successful experience in raising foxes has mainly done the following work:

1. Pay attention to feeding and management to meet the nutritional needs of foxes and young foxes. Zou Benman modestly sought advice from technicians and, referring to fox-raising books, sorted out the feed formula for each breeding stage of foxes and young foxes. In winter, the food was mainly corn flour and mixed fish, supplemented by a small amount of green vegetables, boiled into porridge, and fed twice a day. The average daily food requirement is 0.2 kg, less meat and more coarse grains in summer, because it meets the nutritional needs of foxes at all stages, that is, it improves the survival rate of foxes and young foxes. It also saves the feeding cost. At the same time to solve the fox self-harm and other pica.

2. Pay attention to environmental hygiene and prevent and cure epidemic disease. Northeast silver fox has strong adaptability. The main disease is acute enteritis. Prevention should be done first. First, do a good job in epidemic prevention in strict accordance with immunization procedures. Injection of encephalitis, canine vaccine and other vaccines. The annual epidemic prevention cost is 10.8 yuan per animal. Second, keep the house and floor clean and hygienic. Disinfect the feed and the ground twice a week and clean it once a day to clean up the dirt in time to prevent the spread of germs. At the same time, ensure that the food is fresh and do not feed spoiled food. The northeast silver fox is easy to catch a cold in the off-season season and is carefully managed in the off-season season. The annual treatment cost is only 1 yuan per animal.

3. Improve the breeding rate of foxes. The northeast silver fox breeds once a year, and the estrous period is concentrated in March-May. The duration of estrus is short, which is usually 3 murals for 5 days. Zou Benman observes and records the estrus every morning and evening. The artificial insemination technology was used to successfully inseminate the estrus female fox, and the birth rate was more than 50%. The survival rate reached more than 90%. 4. Strengthen the management of the mother fox during the lactation period. During this period, the mother fox should keep quiet around the fox house, prevent strangers from entering the fox house casually, and do not make any noise. Once the mother fox is frightened, she will hold on to the baby fox all day and refuse to breast-feed. Serious ones may even bite the baby fox to death. Therefore, the lactation mother fox is managed and cared for separately during the lactation period, and the problems found are dealt with in time. The immature foxes were separated and fed in a single cage in time after the full moon. Artificial breeding of northeast silver fox is simple and easy, low risk, as long as careful management and breeding can be successful, is a small investment, quick results, feasible and effective way to get rich.
