2. Pay attention to the feeding density. When grouping pigs according to weight, physique, breed and other factors, it is also necessary to combine the feeding density. Generally, the optimal number of pigs in each pigsty is 10 ~ 12, and the feeding area of each pig is about 1 m2.
3. Be sure to castrate. Castration is castration. Fattening pigs, boars and sows all need castration. Because castrated pigs have no sexual demand, it is more convenient to manage, the feed conversion rate is higher, the growth rate is faster, and the quality of pork will be better. Therefore, all pigs used for fattening should be castrated before fattening.
4. Do a good job of deworming. In order to avoid the influence of parasites on the growth speed and health of fattening pigs, farmers must deworm once after weaning and once before fattening. Because studies have shown that parasites in pigs can at least reduce their fattening rate 10%.
5. Pay attention to feeding methods. Try to keep the feed stable and don't change it easily. If it must be changed, it will take a transition period of about a week. Feeding should adopt the way of eating less and eating more meals, and the residual feed in the trough should be cleaned up in time to avoid being eaten by pigs after mildew.
6. Pay attention to the feeding environment. Ensure that the pigsty is clean and hygienic, do a good job of disinfection, ensure good ventilation, and pay attention to temperature and light. Usually the optimum fattening temperature is between 15 ~ 2 1. The summer temperature is high and the fattening speed is slow; When the temperature is low in winter, the fattening speed will drop sharply. Especially when the temperature is below 4 degrees Celsius, the weight gain rate of fat pigs will drop by more than 50%.
7. Ensure adequate drinking water. Provide enough drinking water for pigs. Generally, each kilogram of dry feed needs to be matched with 5 kilograms to 8 kilograms of drinking water.
8. Pay attention to the training of pigs. Pigs who love to bite the rack should be driven away in time, and farmers can attract the attention of pigs by throwing stones. When pigs live in groups, the social grade should be established artificially. In addition, in order to prevent some pigs from feeding on it, farmers should try to increase the length and material level of the trough.
9. Pay attention to the prevention and control of diseases. Pay attention to the cleanliness of the pigsty environment, generally twice a day, and clean up the manure in time and concentrate it on the manure field. Do a good job in daily health care such as vaccine immunization and drugs and additives. Farmers should pay more attention to the situation of pigs at ordinary times, especially whether their appetite is declining, whether their feces are normal and whether their spirits are normal. Once the abnormality is found, it should be diagnosed and treated in time.
