What are the management points of fattening pigs?

Answer: ① boars are fed twice a day, and each pig is fed 2.5 ~ 3.0 kilograms a day to provide the required nutrition. Feed an egg every day during the breeding period. Don't overeat every meal, so as not to let the pigs overeat and sleep, and don't want to exercise and get fat. (2) Keep pens and pigs clean, exercise reasonably, and arrange driving exercises 2-3 times a week if possible. ③ The reserve boar is 8 months old and weighs 65438±0.20kg. When it is in good condition, it can start training. ④ Reserve boars should be used at the age of 9 months. Breeding and training should be carried out before use, and the quality of semen should be checked. The breeding weight should be above 130 kg. Boars aged 9 ~ 12 months are bred 1 ~ 2 times a week, and boars aged 13 months or above are bred 3 ~ 4 times a week. The rest time of healthy boars should not exceed 2 weeks to avoid reproductive obstacles. Boars are sick, 1 month is not allowed. ⑤ The semen quality of this hybrid boar must be checked once a month and twice a month in summer. Those who fail to pass the fine inspection for three consecutive times or two consecutive times, accompanied by diseases such as testicular swelling, atrophy, low libido and claudication, must be eliminated. Each production line should reasonably arrange the use intensity of boars according to the results of fine inspection. ⑥ Prevent boar from heat stress and do a good job of heatstroke prevention and cooling. When the weather is hot, you should choose to breed in the morning and evening when the weather is cool, and reduce the use times appropriately. ⑦ Brush pigs regularly, drive out ectoparasites in time, and pay attention to protect the limbs and hooves of boars.
