Detailed Explanation of Key Points for Feeding and Management of Foxes During the Winter Fur Period

The main tasks during the winter fur period for foxes are: to supply all the various nutrients needed by breeding foxes for overwintering and for the growth and maturation of the winter fur, to promote the development of the foxes' reproductive organs, to adjust the breeding foxes' reproductive body condition, and to lay a good foundation for mating. This period can be divided into two stages:

During this period, the nutritional needs of foxes are diverse. They should be fed supplemental nutrients to make up for reproductive consumption, promote their growth and development, store the nutrients needed for overwintering, and maintain the substances needed for their own metabolism and to promote the growth and development of reproductive organs. The daily ration should be based on the principle of eating until full. Proportion of animal-based feed: 55%-65% for silver foxes and 50%-60% for Arctic foxes. Feed twice a day, with the morning meal accounting for 40% and the evening meal accounting for 60%. At this time, more feed with high fat content, such as animal offal, can be appropriately supplied to make the breeding foxes somewhat fatter, which helps them overwinter.

Late preparation for mating (December to mid-February of the following year): At this time, the winter fur and the growth and development of young foxes have already matured. The main focus is to promote the rapid development of reproductive organs and the maturation of reproductive cells, and to prompt the foxes' bodies to reach a medium or above-medium level. In early December, adjustment of body condition should begin, gradually reducing the amount of grains and vegetables supplied in the daily ration, so as to reduce feed volume and leave the breeding foxes without a sense of fullness. At the same time, increase exercise to consume excess fat through activity. Increase light exposure, which is extremely beneficial for reproduction. Entering mid-January, feed with odors that can stimulate estrus, such as scallions and garlic, can be added to the daily ration. During this period, the proportion of animal-based feed in the daily ration: silver foxes and Arctic foxes account for 65%-72% and 70%-75% respectively.
