The hot summer weather and high humidity make it easy to cause a lot of adverse effects on the pig industry. The critical temperature for heat stress in pigs is 32°C-34°C.

3. Must ensure sufficient water. In summer, the demand for water from pigs is relatively large. Therefore, it is advisable to feed in thin foods.
