Most early records refer to nomadic peoples who, with their herds and flocks, followed the natural feed supplies. History does not record when dried roughage or other stored feeds were first given to animals. Surplus food crops, such as wheat, other cereals, fruits, vegetables, and roots, may also be fed to animals. Other feeds, such as sugar beet pulp, brewers’ grains, and pineapple bran, are by-products that remain after a food crop has been processed for human use. Some feeds, such as pasture grasses, hay and silage crops, and certain cereal grains, are grown specifically for animals. Ongoing improvements in animal diets have resulted from research, experimentation, and chemical analysis by agricultural scientists.Īnimals in general require the same nutrients as humans. Modern feeds are produced by carefully selecting and blending ingredients to provide highly nutritional diets that both maintain the health of the animals and increase the quality of such end products as meat, milk, or eggs.
