As mentioned thru text Ka Gerry Geronimo is promoting the method of raising pigs natural. However they are still tying up with a FEED COMPANY that makes natural feeds and no antibiotics (as claimed). I forget the name of the feed. Below is a rough description on how they do the pens.
1. Same setup with NFS but bedding are only tapped with rice hull or ipa.
2. The pen includes a provision of a small pool where the water is raised upto the knee of the pigs. It is explained that the pigs are gonna bath when hot, urinate and poop on the pool. the pool are to be cleaned once a day. The space provision of the chicken are the same with NFS.
