The lifespan of a fox is 10 to 14 years, the reproductive life is 6 to 8 years, and the best breeding period for artificial breeding is 2 to 5 years. The fox is an animal that breeds once a year. The breeding season is in spring. The genitals of the fox have obvious seasonal changes due to the photoperiod. There is a close relationship between fox plush replacement and reproduction. Therefore, the scientific artificial light control method can change the fox's reproductive cycle and the maturation period of the coat. However, there are also individual foxes or young foxes who have participated in mating for the first time. Therefore, for the introduction of only 1 to 2 professional households, it is necessary to consider introducing more male foxes during the introduction to prevent any accidents. The reproductive organs of the female fox are in a resting state in the summer (June-August). The volume of the ovary, uterus, and vagina is the smallest. The volume of the ovaries gradually increases from August to October. The follicles begin to develop, and the corpus luteum starts to degenerate until the corpus luteum disappears in November. Rapid growth of follicles, estrus in the spring of the following year, ovulation, this time the fallopian tubes, uterus and vagina correspondingly changed with the development of the ovary, that is, the volume and weight increased significantly. The fox is a spontaneous (continuous) ovulatory animal, and the two ovaries can alternate ovulation. The young fox is sexually mature from 9 to 10 months of age. According to statistics, about 20% to 30% of late young foxes are not fully developed or have heat during the breeding season. The silver fox was estrus in January-March and concentrated in February; the Arctic fox was estrus in March-April and concentrated in March. Adult foxes estrus earlier than young foxes, of course, are also related to heredity. They have prematurely mature hereditary young foxes and are sometimes estrus earlier than adult foxes. Arctic foxes have a significantly more fetal nature than silver foxes. Silver foxes have an average of 4 and a maximum of 10 births per fetus, while Arctic foxes produce an average of 6 to 8 fetuses each and produce up to 24 heads. Therefore, attention should be paid to the characteristics of the Arctic fox's multiple births. When breeding, the fox should pay attention to the adjustment of the fox's body condition. Foxes and Arctic foxes can automatically reduce their weight and weight before entering the breeding season. This is a sign of preparation for the breeding season. However, foxes and Arctic foxes are under captive breeding, and most field homes and breeders tend to be over-fertilized during this period because they do not pay attention to feed energy and protein balance. Therefore, the silver fox enters in December, and the Arctic fox enters in January. It is necessary to adjust the body condition so that the species of foxes can achieve a balanced breeding condition before mating. Otherwise, the estrus will be delayed or not estrused.
