There are four ways to breed blue fox.

This year, 10 households specialized in raising blue foxes in Pulandian City, Liaoning Province have an average litter size of more than 8, which is more than 40% higher than that of local female foxes. According to the investigation, Cai Yu, an expert in raising foxes, has achieved high results in mating rate, pregnancy rate, litter rate, survival rate and economic benefits, with an average litter size of 10.4 in 3 years. Because the breed of blue fox he raised is pure and of high quality, so foxes and furs sell well. There are four main experiences:

Introduction of fine varieties

The male and female foxes raised by Cai Yu are all American blue foxes with large size, long fur, good adaptation, high litter, fast growth and strong disease resistance purchased from the fur experimental breeding base of the Special products Research Institute of the Chinese Academy of Agricultural Sciences in Zuojia, Jilin Province. He is willing to invest in breeding improved varieties. At the end of each year, a careful selection of male and female foxes is carried out to eliminate inferior species, select good varieties and leave no close relatives, so as to ensure good purity and high quality of good varieties.

Match the seeds at the right time

Fox mating period is only once a year, the time is relatively strong, the technical requirements are higher, and the time error is empty. In view of these characteristics, grasp the main estrus mating period of blue fox from early March to late April every year, strictly grasp the oestrus ovulation period of female foxes, and breed female foxes timely and accurately. The combination of natural mating and forced mating was adopted, and single mating, double mating and multiple mating were used to increase the number of multiple mating, which lasted 5 times until the female fox refused to mate. The mating time is controlled at 6: 00 and 17: 00. Pay attention to strengthen the breeding of male foxes, feed nutritious animal feed during the breeding period, add 1 cooked egg and 4 cooked chickens every day, and ensure that the breeding male foxes have good exercise and rest. At the same time, we should do all the preparatory work before mating, establish mating files, and strictly prevent inbreeding.

Do a good job in recuperation management

According to the different growth periods of female foxes, such as estrus, mating, pregnancy and giving birth, animal feeds such as fresh miscellaneous fish and fresh pigs and chickens, hairy chickens and eggs accounted for 50%, 60%, respectively, and plant feeds such as corn flour, wheat bran, peanut cake or soybean cake accounted for 40%, 50% (75% for corn flour, 10% for wheat bran, 15% for cakes). Add vitamins 5% Mel 10%, feed fresh fruits and vegetables 5% Mel 10%. In order to make the milk of the female fox sufficient, the female foxes were fed with 1 egg, 2 hairy chickens, 80 grams of fresh goat milk and 100 grams of fresh chicken liver every day during the breeding period, crushed, cooked and stirred together with the feed and mixed into porridge. The female foxes were fed 3 mi 4 times a day during the breeding period. After 50 days of weaning, young foxes are fed mainly with digestible, nutritious, fresh meat and eggs, and properly fed with fresh chicken liver, fresh fish and fresh vegetables, and make sure to drink enough water at the same time.

Pay attention to epidemic prevention

In line with the policy that prevention is more important than treatment, combination of prevention and treatment, and giving priority to prevention, for infectious diseases such as canine distemper, viral enteritis, viral encephalitis and other infectious diseases with fast infectivity and high mortality, male and female foxes are vaccinated once a year in January and July according to the requirements of epidemic prevention. The common diseases such as bloating belly, enteritis and pneumonia of male and female foxes and young foxes can be observed, discovered and treated in time. After dividing the nests, the young foxes were injected with an anti-epidemic vaccine to drive away the worms, at the same time, pay attention to the cleanliness and hygiene of the fox houses, clean up the feces on the fox cages and clean the floor in time, and pay attention to the heat prevention and cooling of foxes and foxes.
