Why do pig farms using deep-litter bedding need to leave a hard-surfaced platform, and can it be omitted?

Answer: In the south, it is best to leaveone meteror so of concrete floor, mainly because during the scorching heat of summer, at the hottest time around noon, when cooling measures such as ceiling fans, exhaust fans, and sprinkler devices stop due to power outages or other reasons, the pigs can lie on it to cool down. This part can be placed together with the concrete feed trough.
