1. Incubation period (1) The sows should ensure that the pens are clean after delivery, and the excrement in the bed and trough should be promptly removed. Disinfected 3 times a week. (2) Keeping the house dry, the suitable temperature in the incubator of piglets is: 32°C-28°C within 1 week of age, 1 week old until 28°C-22°C in weaning. Observe the feed intake, mental status, and feces of the piglets frequently, and identify any problems that arise in time. The boars that were not used for breeding were castrated from 10 to 15 days of age. (3) Piglets weaned 28-35 days old require quiet environment and hygiene. After the piglet is transferred out, the bed, guardrail, and feed trough must be thoroughly cleaned and disinfected, and the piglet can be reloaded after more than 48 hours of empty circulation. 2. In the rearing period, the piglet leaves the sow and lives alone. It changes from feeding to eating dry food. It is easy to diarrhea, sickness, and death. It is necessary to minimize all kinds of irritation, keep the house clean, the survival rate is above 95%, daily gain. More than 450 grams. (1) It is necessary to pay attention to the health of the sheds, clear the excrement on the net bed at any time, take care of them, and treat the weak pigs in time. (2) For newly weaned weaned pigs, the litters can be placed in columns 1-2, and the weights are basically in one column. Individual weak groups should be grouped individually and special care should be provided. (3) Newly entered piglets restrictively feed the baby pig feeds for about 5 days. They must not be allowed to overeat in order to prevent pull, and then they are fed with a mixture of pig feed and bred pig feed, and gradually increase. The proportion of bred pigs was changed to pigs after 10 days and free access to feed was started. Pigs out of the arch material should be promptly recycled. The nutritional levels of bred pigs were: digestive energy 13.46 MJ/kg, crude protein 16.38%, calcium 0.87%, available phosphorus 0.39%, lysine 0.91%, and salt 0.35%. (4) The temperature in the house is controlled at 24°C-22°C and the relative humidity is 65%-70%. Pay attention to keep the air in the house fresh and have a flexible grasp of the switch window time. There should be a certain lighting time at night, 1 hour before midnight and 1 hour after midnight, which is convenient for piglets to eat. Spray disinfection 3 times a week. (5) When the weight reaches 26-30 kg, go to the finishing house. 3. During the fattening stage of pigs, the physiological function has been basically improved. Generally, it is required to have a daily weight gain of 750 grams or more and consume less than 3.0 parts of the material. (1) Completely clean and disinfect the house before use. Use it for at least 48 hours before drying. (2) Pigs transferred to groups must be grouped reasonably and have moderate density. It is best to use the Raw Material for fattening. If you put in a nest, you should try to keep the pigs whose strength and strength are basically the same and put them in a column with about 10 heads per column. The newly transferred pigs were fed 5 days of raw pigs feed, and then they were fed a mixture of bred pigs and pre-fattening pigs, and gradually transferred to pre-fattening pig feeds for 5 days. After weighing 60 kilograms, feed the pigs in the late period of fattening. (3) All pigs in the fattening stage should adopt free-feeding to ensure adequate drinking water. The bins should be cleaned once a day to prevent backlog deterioration. The feed from the hog arches must be promptly recycled and strictly prohibited. The pre-fattening nutritional levels were 13.25 MJ/kg digestive energy, 16.04% crude protein, 0.62% calcium, 0.31% available phosphorus, 0.83% lysine, and 0.3% salt. The nutritional level at the end of the fattening period was: digestive energy 13.22 MJ/kg, crude protein 14.18%, calcium 0.61%, available phosphorus 0.29%, lysine 0.70%, salt 0.30%. (4) The newly transferred pigs should regularly observe the point of defecation and urine during training within 3 days. Maintain the hygiene of aisles and pens, and clean them once a day in the morning and afternoon. Spray disinfection twice weekly. (5) The suitable growth temperature for fattening pigs is 20°C-15°C, not less than 15°C in winter and not higher than 30°C in summer. The temperature is low to keep warm and warm, and the air temperature is high to enhance ventilation and water cooling. (6) Pigs should be cleaned in a timely manner after slaughter, and the pigs can be re-installed after being disinfected by fire alkali for 48 hours. 4. 20 ml of swine fever vaccine injected at 20 and 55 days of immunization piglet stage; paratyphoid vaccine at 27-30 days; pig erysipelas and pulmonary vaccine at 55 days; first exemption at 30-40 days No. 5 diseased seedlings (high-efficiency), No. 5 diseased seedlings (high-efficiency) at the age of 60 to 70 days; Insecticides abamectin (insect nemesis) were injected subcutaneously before the rearing group; fattening pigs were generally No more immunizations.
