First of all, pigs must be given a comfortable pigsty. A clean and comfortable pigsty can ensure the survival rate of pigs. You can install a camera in the pigsty to watch the pig's every move. This is scientific pig raising.
Second, pigs should keep in touch with veterinarians, and contact veterinarians as soon as they find any abnormality. If any pig is abnormal, it can be isolated first to prevent other pigs from being infected and causing unnecessary losses.
Third, we should choose high-quality feed. If you choose bad feed, pigs will not only gain meat, but also rely on well-known feed factories to ensure the slaughter rate of pigs.
The above is scientific pig raising, I hope I can help you, thank you.
