In the breeding of special wild boars, the role of purebred wild boars, especially purebred wild boars, is very important. It can breed and breed special wild boars with domestic sows, and can also breed 75% with special female wild boars after multiple purifications. 87.5% or even higher purity special wild boar, in order to get a good return on profits.
1. Building of the bar
The purebred wild boar bar is similar to the home pig house, and is divided into internal and external. However, because the purebred wild boar has no fat under the skin and has strong activity, the height of the fence of the activity field should be 2.5 meters. The upper corners of the four corners should be covered with barbed wire or steel bars to prevent escape. The area of ​​the house is 10 square meters and there is a trough. The activity area is 20 square meters for activities and sunbathing, and there is a pool at the corner for drinking water and summer bathing. Import and export always use iron doors.
2. Domestication technology
Pure nature wild boar has both timid, easy-sounding and aggressive aspects. It has poor eyesight, but the sense of smell and hearing is very sensitive. The sound of strangers and strangers can make the purebred wild boar feel uneasy at 20 meters. Two homosexual wild boars can easily cause biting in the same circle. In order to solve this contradiction well, the best way is to raise the two wild boars in the same circle, which is not easy to be shocked, but also very stable and harmonious. In addition, there must be a relatively fixed breeder, usually in contact with wild boar, the keeper will enter and leave the bar to feed, clear the feces or injection, the action should be gentle, so as not to let the wild boar be frightened and rushed. Generally, domesticated purebred wild boars can quickly adapt to changes in the environment. After a long time, they will be as gentle and obedient as the domestic pigs.
3. Feeding technology
The purebred wild boar has stronger disease resistance than domestic pigs, and has a variety of foods. All kinds of melons and fruits can be fed, especially those with sweet and sweet taste, such as watermelon, apple and sweet potato. The epidemic prevention can be carried out according to the epidemic prevention procedures of domestic pigs. Usually, regular deworming is observed, and pigs are prevented in winter and spring.
When purebred wild boars are raised as breeding pigs, in order to prevent the growth of too rich and unfavorable breeding, the energy feed in the feed should not be too much. For mature breeding pigs, animal protein feed should be added appropriately. Two feed formulas are introduced below for reference:
Young wild boar: 32% corn, 10% rice bran, 30% bran, 10% soybean meal, 4% fish meal, 12% crude, 2% bone meal (or calcium hydrogen phosphate), plus appropriate salt, multivitamins and trace elements .
Mature breeding pigs: 30% corn, 8% rice bran, 30% bran, 8% soybean meal, 6% fish meal, and 18% crude (others as above).
The pure wild boar feeds about 1/3 of the domestic pigs, and the weight is 20 kg or less for 3 times, and the 20 kg or more is fed twice a day. The mixture is preferably semi-dry and semi-wet, and is supplied with sufficient drinking water. Purebred wild boars are mostly active at night and feeding, and the feeding should be done earlier and later.
4. Breeding and breeding
Purebred wild boars have a longer sexual maturity period of about one and a half years. Sows are very seasonal, most of them are around the winter solstice, and the rest of the time is generally not estrus or very estrus. By adopting early weaning, artificial aphrodisiac, and postponing breeding, the purebred wild boar can successfully breed 2 litters per year, and the litter can reach 6-10 heads. Once the male wild boar is sexually mature, it can be bred for many years and has a strong breeding ability. A male wild boar can be equipped with 250-300 sows per year and about 3,000 special wild boars. Because pure wild boar skin thick hair is not easy to dissipate heat, summer breeding time should be selected before 5 o'clock in the morning and after 9 o'clock in the evening, after breeding, you should also avoid the public wild pigs immediately drink cold water.
Purebred wild boars adopt natural mating methods. Before breeding, the sows that have already been estrus should be placed in adjacent enclosures so that the male and female sows can smell each other, familiar with each other, and then washed with potassium permanganate solution. The vulva of the sow is put into the breeding.
In the middle and late stages of pregnancy, the breeder should raise it in a single circle, beware of shocking collisions, and increase contact with it to prepare for later delivery and care.
