Management Of Fur Animal Breeder

The selection site is "a hundred year plan". First, we must emphasize the word "light", that is, the breeding site must meet and meet the needs of the fur animals.

Because light is essential for the survival of fur animals, especially for breeding and molting.

The condition of "light" is satisfied, and the rest of the factors such as temperature and humidity are secondary.

"Light" should pay attention to two aspects: illumination cycle and illumination intensity.

Light cycle is directly related to geographic latitude. Low latitude areas with weak light cycle are not suitable for breeding fur animals that are distributed in high latitudes with obvious change of light cycle. The intensity of illumination should not be too weak, too weak will inhibit animal hair and reproduction; nor should they be too strong or too strong. It is not only hot in summer but also easy to heat stroke, and it will make hair color pale and lose luster and reduce the quality of fur.

The selection site should emphasize the word "net".

That is, from the perspective of health, epidemic prevention and epidemic prevention, we should choose the site according to local conditions, so as to reduce the losses caused by epidemics.

"Fat" means fat, that is, the body condition of animals.

Practice has proved that there is a direct relationship between body condition and fecundity in breeding period.

Too much fat and too thin body condition are not conducive to reproduction.

The suitable conditions for breeding animals must be progressively adjusted during the preparation period, and must not be adjusted abruptly during the next mating season.

According to the climatic conditions of all regions, we should gradually reduce the fatness before the maturity of winter hair and the development of sexual organs to the mating season.

At the later stage of mating, the body condition should be slightly lower and thinner, but not too low or too thin. Otherwise, the male sex will decrease and the semen quality will be worse.

The best body condition is: the body condition of mink is round and flat, and the rear crotch is sagging or slightly concave; the fox can identify the outline from the upper arm from the front direction.

The upper part of the arm is flat or concave in the middle, which is too fat. The eggs are large and the eggs are small.

"Love" means aphrodisiac, that is, in preparation for mating period, especially in the mature winter or "winter solstice", it is necessary to promote the growth and development of sexual organs, and prepare for timely estrus and breeding.

Feeding should ensure full supply of protein and vitamin A and vitamin E supplement.

These two vitamins are directly related to the development and maturation of sexual organs, so it is necessary to supply them at the latest at the end of the winter solstice.

It will be too late to double replenishment until the mating season.

Preparations for late breeding should continue to feed the onion, garlic and other stimulating feed, which is beneficial to aphrodisiac and mating.

"Quasi" means that the observation of oestrus identification and mating behavior should be accurate, and the identification of estrus must not be subjective, while the animal sexual behavior is the criterion.

The so-called "look, check, release" comprehensive oestrus identification method, see (see animal sexual excitement, sexual behavior), check (check the morphology of external genitals) are reference, and finally put (to trial) sexual behavior is the accurate standard of identifying estrus.

The word "test" is very important, but try to be right. If mother animals enter the hot season, don't make time too long. Otherwise, the bites between male and female animals will cause sexual inhibition, resulting in artificial breeding failure.

The accurate observation of mating behavior is also important. The exact match, false match and mismatch should be accurately judged.

No observation or doubt is necessary, and sperm count should be used to confirm it.

"Sperm" means that the semen quality of male animals is excellent. Semen quality inspection must be used to confirm the utility value of each male animal, and early to propose and eliminate the male species with poor semen quality.

When the quality of the whole group semen is bad or down, find out the cause in time and take corresponding measures.

Supplementation of liver, brain, milk, eggs and other full price feeds and vitamin A and vitamin E supplements are beneficial to improving the semen quality of male animals.

During the mating season, lighting must be strictly prohibited, otherwise the semen quality and sexual desire will be reduced in advance.

"Fresh" refers to the quality of feed to be fresh.

The requirement for quality of feed during pregnancy is the most rigorous stage in the whole year. We must eliminate all feed that is not fresh, especially rotten and spoiled, so as to avoid the whole group of stillbirths, rotten fetuses and even later generations.

"Full" refers to the full nutritional value of the diet during pregnancy.

Under the premise of fresh feed quality, a mixture of different feeds is beneficial to improve the nutritional value of the diet.

The supply of full protein feed, such as essential fatty acids, vitamins and inorganic salts, should be guaranteed in the diet.

"Warming" means that the production box should be dry and warm.

The three main factors of motherhood are motherhood, temperature and milk, and the three animals are not able to survive.

The temperature of the box is particularly important in the early stage of litter production.

Not only directly affects the vitality of the beast, but also related to the growth and development of young animals.

In order to achieve the drying and warmth of the production box, we must do the disinfection of the small room and the work of keeping the litter warm before the labor.

Although the temperature difference between the north and the south is large, and the amount of floc is in line with local conditions, the author thinks that it is necessary rather than unnecessary.

Because the mat grass has the function of keeping warm, it is also beneficial to the young animals to hold together, suck and absorb moisture.

"Milk" means that the milk of the litter mother is better. Milk is the only food and nutrition source in the early stage of the beast. Therefore, the quantity and quality of the milk directly affect the survival rate and growth of the young animals.

In order to promote the milk production and improve the quality of the mother's milk, this period should not limit the amount of feed produced by the mother, and supplement the milk, eggs, liver and meat in the diet.

In the management, the lactation condition of the litter mother is checked at any time through its behavior and the growth and development of the young animal, and corresponding measures are taken.

For primipara and lactation mother animals, it is possible to use drugs to stimulate lactation. During lactation, it is found that breast inflammation, lactation, milk quality and growth retardation of animals should be adopted in time.
