(I) Nutrition of Boars
1. The diet should be based on the situation of the breeding period, breeding period or year-round breeding, combined with boar's body condition and semen quality, formulate a special boar feed formula, and can not feed the boar with pig material;
2. For young boars after 100 days or 180 days, feed restriction is applied, and the daily feeding amount is about 3.0 kg. For adult boars, the daily feeding amount is about 2.5 kg. In the season of breeding, increase the daily feed by 0.5 kg or add eggs (1-2 pieces per day) in the diet to keep the boar exuberant. Feed 3 times in summer and 2 times in winter. When seasonal or perennial use intensity is high, VE should be no less than 25 mg per kilogram, selenium should not be lower than 0.1 mg, and attention should be paid to the addition of biotin. ;
3. To increase boar libido, ejaculation volume, and sperm motility, appropriate amount of green feed or silage should be fed. The general amount of feed should be controlled to account for about 10% of the diet (calculated as air-dried material), and can not be fed too much, so as not to form a grass belly.
(B) Breeding Management of Boars
1. Screen individual boar individuals with good traits according to species requirements. General requirements boar pure, large testes, bilateral symmetry, more than 7 pairs of nipples, body robust and flexible, moderate sensation, flat line without sagging;
2. Outsourcing male boars should be purchased on the pig farms in the epidemic-free areas. After the boars are transferred back, the boars will be isolated and reared. No overfeeding will be allowed within 5-7 days. After the pigs are fully adapted to the environment, they will be transferred to normal feeding. Hey, and do a good job of immunization and parasite extermination;
3. The implementation of single-circle feeding, regular quantitative feeding, to ensure adequate clean drinking water, training boars fixed point defecation, do winter cold and warm and summer heatstroke work;
4. Strengthen the boar movement, regularly drive away and get rid of exercise for 1-2 hours a day;
5. Wipe once a day is beneficial to promote blood circulation, reduce skin diseases, promote human pig affinity, not brutal beating, so as to avoid bogey and other resistance to bite; use the boar to lie and rest, wipe from the touch Initiate the use of knives to trim all kinds of irregular hoof shells and reduce the occurrence of hoof disease;
6. The insects must be repelled before the breeding, and the vaccines such as JE, parvovirus, swine fever and streptococcus can be injected in time;
7. Reserve boars are to be bred for training and artificial assistance is needed during the initial distribution to prevent the pigs from falling or the sows with poor body condition and low weight being bruised by boars.
8. The first-time young boars can be planted 2-3 times a week for the first month. Young boar breeding should be performed once every 2-3 days. Adult boars should be bred once a day and occasionally can be used twice. 5- 7 days off for a day; for breeding time, in the early morning and one evening in summer, when the winter is warm, don't feed for 1 hour before and after mating, and it is forbidden to wash the body with cool water after breeding; after the boar has fever, it is forbidden to use within one month; Poor boars can intramuscularly inject 175 micrograms of cloprostenol but not during summer.
9. Occasionally collecting boar semen for microscopic examination, assessing semen quality, adjusting feeding and management, and maintaining the normal mating ability of boars;
10. Strict implementation of the breeding program, so that a good match, do not miss the distribution, fill in the records carefully, and prevent close parental breeding;
11. Timely elimination of boars that cannot be used for breeding.
Feeding and Management Objectives: Successful breeding of male boars with physical and limb-strength, strong libido, good semen quality, and gentle temperament can accomplish mating and fertility tasks.
Currently there are problems: impure species, more diseases, weak limbs and feet, poor reproductive performance, and short service life.
The quality of the boar affects the entire herd. As the saying goes, “The sows are good, they have a good nest, the boars are good, and they have a good slopeâ€. Therefore, it is very important for the boar to keep the boar. Under normal circumstances, using this product, each boar can bear 20-30 sow mating tasks, 400-600 heads of piglets can be born each year, and with artificial insemination, more than 10,000 piglets can be born per head per year.
