Feeding Management of Growing and Fattening Pigs
1. for the fattening of purchased piglets, high-quality healthy piglets should be selected in the epidemic-free area. after the piglets are transferred back to the epidemic-free area, the piglets should be quarantined and raised in isolation, and should not be overfed within 5-7 days. After the pigs have fully adapted to the environment, they should be transferred to normal feeding, and do a good job of vaccination and parasite elimination.
2. The growing and fattening house should be thoroughly cleaned, sterilized and dried before it can be transferred to the care of pigs.
3. Conservation pigs should be divided into groups reasonably, and the original nest or group should be transferred to a column as far as possible, so as to avoid recombination bite stress.
4. After changing groups, it takes at least 5-7 days to train for food intake, drinking water, excretion and sleep, so as to create a comfortable living environment.
5. Provide comfortable growth environment for pigs, and pay close attention to the effects of density, temperature, humidity, light and other factors on pig growth.
6. Provide sufficient and clean drinking water, generally, the amount of drinking water is about 2-3 times of food intake in winter, 4 times of food intake in spring and autumn, and 5 times of food intake in summer. the sink should be separated from the material trough. Automatic drinking fountains should often check the flow rate of water to prevent poor water flow from affecting drinking water.
7. Timely vaccination, medication and elimination of internal and external parasites in accordance with procedures
8. Check the food intake, drinking water and health status of pigs every day, and deal with sick, disabled and dead pigs in time.
9. Implement full-in and all-out management to break the spread of disease among pigs.
10. Control the occurrence of chronic proliferative enteritis and chronic consumptive diseases such as respiratory diseases
11. record the transfer, death and feeding of pigs, and systematically analyze the feeding and economic benefits of pigs.
12. Sell at the right time according to the market situation. At present, the body weight of commercial pigs is generally 90-120 kg.

Camp breeding of pregnant sows
1. In the early stage of pregnancy (within 4 weeks after mating), the embryo needs almost no extra nutrition, and if the feed intake of the sow is large, the death of the embryo will be increased, so the intake should be limited at this stage, with a daily feed of 1.5-2.0 kg. Weaning sows in particularly poor condition can be fed more feed. The dietary nutrition level is as follows: digestible energy 2900-3000 kcal / kg, crude protein 14% Muth15% Port2.The second trimester of pregnancy (4 weeks after mating to 4 weeks before parturition), at this stage, the daily feeding is limited according to the body condition of sows.
