Animal Welfare Institute
With this label you know that the animals are not kept in cages, crates, sow crates or on tethers. Genetic engineering, hormones to produce unnatural growth and weight gain are not allowed. Antibiotics to compensate for unsanitary living conditions, feed that has genetically modified organisms (GMOs) or supplements or animal products, are prohibited. Animals will not experience hot branding, tail-docking, debeaking or detusking of breeding male pigs.
Basically, this label states the above as well as the fact that animals are allowed to live a natural life. There are no overcrowded facilities and the animals can move about freely. Abundant water must always be available, along with continuous access to the outdoors and shelter. All farmers agree to comply with all visits by the AWI or any of the AWI's agents.
