Pre-mating silver fox is ready for breeding from December to next January, and blue foxes can be extended to February. The main task during this period was to adjust the nutritional level of the diet and increase the proportion of protein in the diet so that the breeding fox could reach a moderate upper body condition before breeding. For over-fertilized and over-sized foxes, different nutrient standards should be applied to make them weigh up to 56 kg before mating. At the same time, gradually increase the light to stimulate gonad development.
The mating period of silver foxes is in February and March, and blue foxes are in March and April. During this period, it is necessary to provide fodder with abundant nutrition, good palatability, and digestible feed, and to appropriately increase the ratio of trace elements and vitamins in feed. Vitamin E20-30 milligrams, 4-5 grams of onion or garlic, and 1-1.5 grams of trace elements can be added per kilo of feed.
During pregnancy, we must pay attention to the supply of nutritious, high-quality feed, must not be fed with mildew spoilage feed to prevent abortion. At the same time, we must also do a good job of hygiene and disinfection of the fox house, keep the fox house quiet, and minimize the occurrence of stress factors.
During the lactation period, the follicles of the mother have poor appetite in the early part of the farrowing period, and it is better to feed them less frequently. Three days later, they are fed three times a day, with regular quantification. Aberdeen foxes grow up to 25 days of age and should normally be supplemented twice daily. Fresh fish, liver, eggs, milk, etc. can be adjusted into a paste when feeding, allowing the fox to feed and return to the original nest after feeding.
During the rearing period, young foxes are generally weaned at 45-50 days of age. Those who are physically strong and have independent living ability should split their nests early; weaker ones should postpone their nesting time. After the fox has been divided into follicles, it enters the rearing period. Because the foxes grow faster at this stage, the plush growth in the latter stage is rapid and requires a large amount of nutrients. Therefore, the fox should be eaten as much as possible to ensure its normal development.
