Sawdust + IMO4 = A Pig Pen Nobody Cleans for 3 Years
Fifteen more minutes of slides, now pigs. Cho shows the wing-curved roof, houses 2 m apart with perilla between, and the floor bed of logs, sawdust and IMO4 that lets one housewife keep 300 pigs with no cleaning for 3 years. Then free sow pens, a Chinese pen at minus 40, a fermented feed box, food scraps and pig dung turned into feed, piglets on the first nipple, and a stress-hormone slide. The session ends: 'that is love', and the rest tomorrow.
