1. Breeding in the rearing period
The young fox grows rapidly during the period from 2 to 5 months of age and must supply sufficient nutrients to meet its needs. Until the fox enters 6 months of age, its energy needs to decline.
Insufficient energy can cause growth retardation, and a severe lack will lead to weight loss and dull coat color. The oxidation of fat in feed reduces the nutritional use of essential fatty acids. Breeding animals are prone to yellow adipose disease. If lipids in the feed are found to be oxidized or yellow follicles develop in young foxes, feeding oxidized fat or increasing the amount of vitamin E in the diet should be stopped. 8 to 25 weeks old foxes, in order to obtain the maximum nitrogen storage, must provide more than 41% of the dry matter weight of protein. When the digestible protein content in the diet of the bred fox was less than 30% of the metabolizable energy, the young fox had a normal body weight but the body length was slowed down. About 5 to 6 months of age will grow to adult fox size.
The young fox has a strong metabolism and high feed utilization rate. The diet requires full nutrition, cleanliness, easy digestion, fresh and good feed quality. Three times during the breeding period, the young foxes for 90 days or more only replenished three or two mixed fish per day. The amount of corn flour was appropriate. The amount of feed should be adequate, based on the principle of eating without food. In the breeding period, to prevent the occurrence of nutritional deficiency diseases, inorganic salts, various vitamins, trace elements, yeast powder, vitamin A, vitamin B1, B2, vitamin C, and sodium selenite E powder should be added to the feed. Recharge, to meet the needs of nutrition.
Within 100 to 150 days after birth, young foxes have a particularly rapid growth and growth, which is the period during which bones and muscles grow rapidly; especially around the age of 2 months after weaning, it is a crucial period for determining size. Therefore, we must pay attention to increase the amount of feed in a timely manner, and we must not be hungry and full. The supply of protein in the diet during this period must be kept above 45 grams per day. Later, as the growth rate slows down, the protein supply can gradually decrease, but each day can still not be less than 35 grams. If the protein supply is insufficient or nutrition is not sufficient, the future height and height of the young fox will be directly affected. Missed this period, feed no matter how good it grows, it can only grow into a rough, grow into a short thick fat.
2, the management of the fox breeding period
After 7 weeks (49-60 days), the foxes can be weaned and separated from the female fox. The young foxes that have been weaned are best placed on the crate, continue to use, cool in the summer, and the young foxes are easy to catch cold.
(1) The mesh of the cage of young fox cages should not be too large, especially the bottom of cages that are welded in parallel with iron bars. The distance should not be too wide. Otherwise, young foxes would not dare to walk on them. They could only be frightened or not, or all four legs would be hung under the cage. The belly would not move under the cage, so that the food eaten by the young fox could not be digested all the time. And the phenomenon of death. If the bottom of the cage is large or the distance from the iron is wide, adding a 3 cm 3 cm or 3.5 cm 3.5 cm iron mesh to the bottom of the cage can avoid this problem.
(2) When a fox grows into a fox, it is very hot in summer and the temperature is high. At this time, it is necessary to prevent heat stroke and food poisoning. (Other foxes should also pay attention to prevent heat stroke and food poisoning). To keep the fox cages well ventilated, the fox field has the conditions to shade the front and back trees of each fox cage.
(3) Incubation fox 2 months after injectable canine distemper, viral enteritis, encephalitis and other vaccines to prevent the occurrence of various infectious diseases.
(4) In this period, we must do a good job of selecting new species of foxes. In order to ensure high productivity, the age composition of the fox must be controlled. The practice of raising foxes has proven that the 2-5-year-old female fox has the highest reproductive ability, so it is necessary to add a certain amount of young foxes for foxes each year. The number of supplemental foxes generally does not exceed 40% of the population. Selecting and keeping the reserve fox is a detailed, complicated and technical work. It should adhere to the method of selection and selection of the entire group.
The conditions for keeping the foxes selected are early birth, big heads, and good coat color. Its mother fox has more than 10 litters and has strong lactation capacity and high survival rate. The female fox must also have normal genital development and more nipples; the male fox must have thick limbs, complete testes and normal development.
Selected to stay in the young fox to male and female parent breeding, make a mark, lay the foundation for the second selection. The first time the best type of work was performed was performed at the weaning nest, and the second time the selection was performed around September. The rearing and management of the young foxes determined after two selections can be the same as the rearing and management of the original breeding fox. In the first half of December, the skinning period will be selected and selected according to the standard of the raised fox.
(5) For each group of bred foxes, two insects are used to cleanse each of the two worms or one or two insecticides.
(6) If a fox is suffering from a self-bite disease, it usually appears in late August. At the beginning, they often veer towards one side; after a while, some young foxes became aggravated, and at the same time they whirl around, they bite their hind legs or tail roots, and they emit squeaky squeaks. Most of the self-bite leprogopus lose their muscles on the hip or both sides of the thigh, and even pull off their tails; they severely bite the skin. Even if the fox does not die, it will not be able to sell for a good price due to damaged skin.
Treatment of self-bite fox: Feeding thiazapidine tablets 3 times a day, 1 tablet each time; or feeding belladonna tablets, vitamin B1 1 tablet twice a day, or chlorpromazine, chlorpheniramine 1 tablet, 2 times daily.
The time from the splitting of the fox weaning to the removal of the skin is referred to as the breeding period. The following feeding and management work should be done during this period.
