1 Breeding management during mating season Currently, most of the rearing households rely on feeding silver fox and blue fox. The silver fox enters breeding preparation period from December to January, and the blue fox breeding preparation period can be extended to February. Therefore, in the early period of mating, in November, the species to be used as a breeding stock should be carefully checked once again, and the individual hair replacements will not be good enough, the body size is not enough, the development is not strong enough, the coat color is not good enough, and the fox The foxes that are not good enough for the milk, are not strong enough for the nurses, have a record of eating, and have self-bite are strongly rejected. In addition to this, the main task during this period is to adjust the nutritional level of the diet and increase the proportion of protein in the diet so that the breeding fox can reach an upper-middle level before breeding. For over-fertilized and over-slim foxes, different nutrient standards should be implemented to achieve 5 to 6 kg before mating. At the same time, increase the lighting time of the male fox, promote the development of sex organs and the secretion of sex hormones. During the day, the male fox should be introduced to improve the physical quality. The male and female foxes should also be replaced by cages or male and female foxes for sexual stimulation. Promote the fox early estrus.
2 Breeding period of breeding and management breeding period is a key period for fox reproduction. The breeding period of silver fox is from February to March, and the breeding period of blue fox is from March to April. In the breeding season, the appetite of the foxes generally declines. Therefore, fresh fodder, which is rich in nutrients, good palatability, and easy to digest, must be supplied during this period, and the proportion of trace elements and vitamins in the fodder should be appropriately increased. Each kilogram of feed can add vitamin E 20 to 30 milligrams, onion or garlic 4 to 5 grams and trace elements 1 to 1.5 grams, can also add some fresh liver, animal brains. In addition, we must also pay attention to the management of the breeding period, and check the situation of the estrus of the female fox every day. Identification method of female fox estrus: First, observation behavior. The estrus mother fox often shows fidgeting and reduced appetite. The second is to observe changes in the genitals. The female fox is swollen with ovulation, with prominent protrusions. There is a thick, white discharge with a special odor in the vagina. The mating method is to place the estrus fox in the female fox cage and allow it to mate freely, and then compound it again on the second day. Carefully close the cage at any time to prevent the foxes from running off, prevent bites, ensure the quietness of the fox field, and keep the fox cage, ground, and utensils clean and hygienic, and disinfect regularly.
3 Feeding Management during Pregnancy Pregnancy is the most crucial period for determining the success or failure of production. The central task of feeding and management during this period is to ensure the normal development of the embryo. The demand for nutritious foxes during pregnancy is especially strong. Attention should be paid to feeds that provide comprehensive nutrition, good quality, good palatability, and easy digestion, and should not be fed with rotten spoilage feed to prevent miscarriage. Its suitable feed ratio is: 73.6% for animal feed, 12% for cereals, 11.9% for vegetables, and 2.5% for additives. At the same time, we must also do a good job in sanitation and disinfection. The gestation period of the fox is generally 51 to 52 days. Be sure to keep the fox house quiet and minimize the occurrence of stress factors.
4 Feeding and management during lactation The mother fox is called lactating from the time of farrowing to the time when the fox is weaned. The shortest is 35 days, usually 40 to 45 days. Feeding and management during lactation is to ensure that the fox lives and develops rapidly. Silver foxes are usually born from late March to late April. Blue foxes are usually born from mid-April to early June. The quality of feeding and management during this period will directly affect the milking power and duration of the fox and the survival rate of the fox. The main task of this period is to feed high-quality full-priced feeds so that the mother's fox secretes sufficient milk. During this period, the proportion of suitable fodder for female foxes is 73.4% for animal feed, 12.2% for cereals, and vegetables. 12%, additives 2.4%. At the same time, we must also maintain a quiet environment to ensure healthy growth and development of the Fox and increase the survival rate of the Fox. The early follicles of female foxes have poor appetite, and it is better to feed them less frequently. Three days later, they are fed three times a day. Regular rations, and foxes grow to 25 days of age, should be supplemented, usually 2 times daily, not only It can relieve the nursing burden of the female fox, and it can meet the needs of the growth and development of the fox. From the 20th day of the young fox, it is necessary to feed easily digestible eggs, milk, animal liver and fresh meat, and adjust it into a paste, let the fox feed, feed it and return it to the original nest. After the foxes are born, especially when they are farrowing, all abnormalities can cause the female fox to show varying degrees of unease, resulting in the occurrence of abnormal and harmful behaviors such as biting, biting, eating, refusing to nurse, moving, and abandoning. . Therefore, it is very important to keep a quiet environment. Breeders should take extra care. During the farrowing period and after the farrowing period, it is strictly forbidden to have noise or outsiders to enter the fox house. Do not check the litter size prematurely or rough before 20 days. When the mother fox has a childbirth, and the farrowing is outside the breeding box or on the cage net for a long period of time without failing to enter the breeding nest, if the abnormal fox sounds or the fox does not enter the birth box for a long period of time, take necessary inspection measures to prevent accidents. occur.
5 The main task of the restoration and management period of the recovery period is to ensure that the consumption of the consumptive fox in the breeding process is fully replenished and restored, which lays a good foundation for the reproduction in the second half of the year. For this reason, the daily feeding amount in the first month of the recovery period should be kept at the same level as the breeding period. After the recovery period of the body condition, it is gradually transferred to the maintenance period for rearing.
6 Rearing and management of the breeding period The young foxes are usually weaned at 45 to 50 days of age. The production can be controlled flexibly according to the growth and development of the fox. The physically strong, independent living ability should be divided as early as possible, and the weaker body should postpone the splitting time. After the fox is split into follicles, it enters the rearing stage. Because the young fox grows faster and the follicles grow rapidly in the later period and needs a lot of nutrients, the fox should be eaten as full as possible. The appropriate feed ratio should be: animal feed. Accounted for 65%, cereals accounted for 16.1%, vegetables accounted for 16.4%, and additives accounted for 2.5%. In September and October, let the breeding fox freely eat, do a good job of sun protection, rain, heat stroke prevention work, and the entire group of injections of dog fever, foxcephalitis and viral enteritis and other vaccines. Into the winter hair growth period, we must do a good job in cage care, to avoid the appearance of tangled fur, parasite skin, affect the quality of skin.
The bred foxes generally mature at the end of November and early December, when they can be slaughtered and skinned. The signs of mature fur are: rich hair, straight hair, shiny hair, and fluffy tail hair. When turning into a fox, there is a "crack" between the hairs of the neck and the body, and when the hair is opened, the pink skin can be seen.
