Young herbivores learn which foods are harmful and which are safe through interactions with their mothers. Throughout life, they learn about the consequences of eating through postingestive feedback they experience after eating foods. But how can they do this in a world where toxin and nutrient levels of forages change daily and seasonally? How can they possibly learn and remember all the plants that grow in pastures and on rangelands? How can they survive when we move them to new pastures with unfamiliar foods?
