There is growing demand in Iowa for pigs raised outdoors or in a deep-bedded system without the use of antibiotics, growth promotants, or animal by-products. Currently, most producers selling naturally raised pork market their animals to a company that requires adherence to the Animal Welfare Institute’s (AWI) Animal Welfare Standards. One of the key components of these standards is the prohibition of farrowing crates. While a pasture farrowing system is effective during spring, summer, and fall, an alternative system is needed to farrow pigs in the winter for the naturally raised pork market.
