Pigs are very clean and they tend to keep their bedding dry and clean.
Pigs make funny sounds like grunts and squeals. Domesticated pigs eat ground up corn, soybeans, wheat, and grain sorghum. The skin on pigs is pink, but the hair can be different colors. Pigs can't sweat, farmers use sprinklers and fans to keep pigs cool. Pigs not under fans will wallow in mud to keep cool.
