Always keep the breeding pigs clean and dry, with plenty of sunshine, air circulation, warm winter and cool summer, so that they have a good living environment. In addition, we must do the following work.
1 single-round breeding
The boars are kept in a single circle to prevent jumping and self-detainment. Adult boars are kept in a single circle, far from the sow ring, the wall is tall and strong, and the door should be tight and firm, which can prevent the estrus sows from interfering with other breeding pigs and make the boars rest quietly. , normal feeding, prevention of boar bite accidents and boar self-depression. When the mating ring to prevent movement of the outer and the sty two well met, boars biting minimize accidents, to facilitate breeding breeding work.
2 Management Specifications
It is necessary to establish a normal daily feeding management standard for breeding boars, arrange feeding, drinking water, exercise, brushing, rest, etc. of the boars to make the boars develop a good living law and maintain good body condition. Improve the ability to breed and extend the useful life of the boar. Treat boars should not be rude, nor whipped, otherwise it would be easy to hurt a boar.
3 often brush
Regular brushing can also make the boar temperamental, easy to collect and vaccinate. It is best to brush the pig body 1 or 2 times a day with a hard brush or bamboo broom to remove dirt from the body surface and prevent skin diseases and ectoparasites (such as swine fever, sputum). It is important to promote blood circulation and promote metabolism by brushing the skin. In the hot summer, the boar can be bathed in shallow water for 1-2 times or once with water spray.
4 regular weighing
The boars are weighed once every half month or one month, and the weight changes are learned by weighing to adjust the nutritional level of the diet and maintain a good seed condition. For large-scale boars with excessive body weight, in order to prevent natural mating from injuring sows, breeding racks and artificial assisted breeding should be established.
5 Strengthening the movement
Proper and reasonable driving movement can enhance the appetite of the boar, enhance physical fitness and improve reproductive function. In the non-breeding season, exercise should be strengthened, and the breeding season should be properly exercised. Generally, each exercise is performed once in the afternoon, and the speed is not too fast. This article comes from the pig farm power network. Conditional can be combined with grazing exercise, summer in the morning and evening, winter and spring season should be carried out at noon, cold, snow or hot weather should stop sports.
6 check semen
Whether it is natural mating or artificial insemination, the breeding boars should be regularly checked for semen quality, including sperm density, vitality and semen volume, color, and sputum. During the breeding period and preparation of breeding, every 3 to 5 days to check, found that abnormal dead sperm, weak sperm breeding pigs should be eliminated, strengthen feeding management, but also provide a basis for nutrient, exercise and breeding strength, so that it grows healthily , give full play to the good breeding effect.
7 regulation temperature
The optimum temperature for the boar is 18 ° C ~ 20 ° C. In summer, when the temperature is high, it is necessary to prevent heatstroke and cool down. The effect of high temperature on the boars is particularly serious. The appetite is reduced, the libido is reduced, the semen quality is worse, and even heatstroke death. There are many measures for heatstroke prevention and cooling, such as ventilation, watering, bathing, shading, etc., and localities can operate according to local conditions. Winter pig houses should also pay attention to cold insulation to reduce feed consumption and disease.
8 attention to hoof repair
Pay attention to the hoof of the boars to facilitate breeding, which can prevent the sow from being scratched across the breeding. Care should be taken to protect the legs and hooves of pigs, and to repair hoofs on bad hoofs. Unhealthy hoofs can affect activities and breeding; if hoofs are found, they should be treated and strengthened.
