Feed labeled “organic” must meet very specific requirements. Organic plants are required to be grown with natural fertilizers and without pesticides or hormones, among other things. Livestock that is organic must be fed organic feed and not be given animal byproducts, antibiotics or hormones.
Genetically modified organisms (GMO) have had their DNA altered to increase resistance to herbicides, improve nutritional content, or a variety of other reasons. Most GMO foods are plants such as corn, canola or soybean. Non-GMO feed is made by grains that have not been genetically altered, but may have been treated with pesticides.
Non-GMO Feed is not necessarily organic, but organic feed is always non-GMO.
