First, the fox house construction will generally build a fox house cage type. The cage is a sports field and is 200-300 cm long. Welded with a triangular iron frame, we use a welded wire net to surround it. Leave a hole 40 cm high, 30 cm wide, and two holes 15 cm in diameter on the other side. Hang the food sink outside the cage.
A hole with a diameter of 35 cm is left at the bottom of the cage connected to the nest chamber. The length of the chamber is 100 cm and the width is 90 cm. It is made of 3 cm thick wood, and the bottom of the cage can be used to leave a 2 cm gap for easy leaking. stool. The bottom of the fox cage and nest should have a height of 40 cm from the ground, which will help prevent moisture and clear the excrement.
Second, the reproduction of fox The silver fox begins to heat in late January of each year. During the estrus period, female foxes are highly swollen and their colors are pink. White vaginal discharge and viscous secretions occur. At the same time, the female foxes are active, frequently urinating, have a temperate temperament, and constantly make urgency calls. This is the best time for mating. The female fox should be caught in a male fox cage for mating, using a continuous mating or compounding method every other day. After five days of mating, female foxes contracted and their food intake increased. During the period of 50 to 61 days of gestation, the average litter size was 7 and the number of litters was 12 to 13 and the number was one.
Three, fox feeding and management
1. Fertility of male and female foxes during breeding period due to libido: appetite decreased, physical exertion was heavy, and public foxes were frequently mated, resulting in greater nutrient consumption. Therefore, this period should provide high-quality, full-price, palatable, digestible feed. Appropriately increase the proportion of fresh animal feed, so that the public fox has a strong, long-lasting breeding ability and good semen quality; female fox can normal estrus, timely breeding.
Examples of diet formula: sea miscellaneous fish 55%, meat 10%, egg 5%, milk powder 1%, grain 8%, bean powder 1%, cabbage 8%, water 12%, plus salt 1.5 grams, yeast 7 grams , bone meal 4 grams, garlic 5 grams, cod liver oil 2000 units, vitamin C25 mg, vitamin E25 mg. The public fox participating in mating should also be fed once at noon to supplement appropriate amounts of meat, liver, egg yolk, milk, and brain. During this period, we must keep clean drinking water or crushed ice in the basin every day. We must always clear the excrement in the chamber and change the bedding.
2. During pregnancy, Silver Fox must provide high-quality fresh feed for gestation. It is forbidden to feed feeds that have been stored for too long. The types of feeds should be diversified. Examples of rations include: 52% of sea miscellaneous fish, 7% of meat, 5% of eggs, milk powder 3%, bean powder 2%, pellet feed 9%, cabbage 10%, water 12%, plus salt 2.5 grams, yeast 8 grams, bone meal 6 grams, cod liver oil 1500 units, vitamin C35 mg, vitamin E4 mg.
The appetite of the pregnant fox is generally increased, but it cannot be increased at the early stage. It is advisable to maintain the upper-middle body condition in the early stage. The general appetite before and after maternal fox production declines, and the diet should be reduced by one-fifth of the total amount, and the feed should be diluted. At this time, drinking water should increase, and sufficient drinking water should be provided. At the same time, keep cages dry and clean, pay attention to feed hygiene, strictly sterilize food, and keep the farm quiet.
3. The litter during lactation and lactation should maintain the level of gestation. The variety of feeds should be diversified as much as possible, and appropriate digestible full-rate feed such as eggs, milk and liver should be properly increased.
Formula example: sea miscellaneous fish 50%, meat 6%, egg 7%, milk powder 5%, bean powder 2%, pellet feed 6%, cabbage 10%, water 14%, plus salt 2.5 grams, yeast 8 grams, Bone meal 6 grams, cod liver oil 1500 units, vitamin C 30 mg. The appetite of female foxes increases rapidly around the week of littering, and the amount of feed should be increased on a daily basis according to the number of births, the age of the fox, and the appetite of the female fox.
The fox usually starts to feed the female fox into the feed box 20 to 28 days after birth. Therefore, the fox processing in this period should be finely crushed and easily digested and absorbed. 4 to 5 weeks old foxes can be crawled from the box to the cage to eat, in order to avoid catching food, the feed can be placed in a pot for supplementation. At this time, the female fox still keeps feeding in the produce box. Therefore, it should always do a good job in the production box to ensure the safety of the mother.
4. During 2 to 3 weeks of weaning in the young fox period, 2 to 3 young foxes are raised in a cage and can be raised in single cages at the age of 3 months. During the young fox period, sufficient nutrients for growth and growth and plush growth are to be provided to provide fresh and high quality feed.
The fodder fox diet formulae are as follows: 52% of sea miscellaneous fish, 5% of meat, 14.5% of grain, 2.4% of soybean meal, 12.6% of cabbage, and 13.5% of water. Plus salt 1.5 grams, bone meal 4 grams, yeast powder 7 grams, vitamin A700 units, vitamin D120 units, vitamin B.
