The use of minerals in livestock feeds is constantly evolving. The English word mineral comes from the Latin word minerale, which means “to be mined from the earth”. The first livestock minerals were rocks mined from the earth, then ground up, processed, and fed to animals. These minerals are referred to as inorganic minerals and they are still used in livestock feed; however, they have limitations. Due to scientific advancements, many minerals are now available in multiple forms beyond mined rock. One of the most advanced types of livestock minerals, chelated minerals, have many benefits.
