The life span of the fox is 10 years to 14 years, and the breeding period is 6 years to 8 years. The best breeding period for artificial breeding is 2 years to 5 years. Fox is an animal that breeds once a year. The breeding season is in spring. The reproductive organs of the fox have obvious seasonal changes due to the photoperiod. Fox's plush replacement is closely related to reproduction. Therefore, the scientific artificial light control method can change the reproduction cycle of the fox and the maturation period of the coat. However, there are also some old foxes or young male beasts who have participated in breeding for the first time without breeding ability. Therefore, for the professional households with only one group of -2 groups introduced, it is necessary to consider introducing more than one male fox for introduction. 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 ovary increases from August to October. The follicle begins to develop and the corpus luteum starts to degenerate until November. The corpus luteum disappears, follicles grow rapidly, estrus occurs in the spring of the following year, and ovulation occurs. At this time, the fallopian tubes, uterus, and vagina also change correspondingly with the development of the ovary, ie, the volume and weight increase significantly. Fox is a spontaneous (sustained) ovulatory animal, two ovary can alternate ovulation, young fox 9 months of age - 10 months of age sexual maturity. According to statistics, about 20%-30% of young foxes born late are not fully developed or have estrus during the breeding season in the following year. The silver fox estrus was concentrated in February in January-March, and the Arctic fox was in February-April and concentrated in March. The fox of adult fox was earlier than that of the young fox. Of course, it is also related to heredity. Her foxes have prematurely mature hereditary foxes, and sometimes they are estrus earlier than adult foxes. The Arctic foxes have significantly more fetal characteristics than silver foxes. Silver foxes have an average of 4 and a maximum of 10, and the Arctic foxes have an average of 6 heads and 8 heads and produce a maximum of 24 heads. Therefore, attention should be paid to the multiple characteristics of the Arctic fox in rearing. When breeding, the fox must pay attention to the adjustment of the fox's body condition. The fox and the arctic fox can automatically reduce the weight and weight before entering the breeding period in the natural state. This is a sign of preparation for the breeding season. However, foxes and arctic foxes are under captive breeding. Most field homes and breeders tend to experience over-fertilization of foxes because they do not pay attention to feed energy and protein balance. Therefore, when the silver fox enters in December, the Arctic fox enters in January and needs to adjust its body condition so that the foxes can achieve a balanced breeding condition before mating. Otherwise, the estrus will be postponed or not at all.
