In 1956, the Company was formed as a sales representative agency for manufactures of ingredients used in the production of animal feed, pet and companion animal food, and pet treats. In the 1950s, progressive nutritionists were looking for ingredients that could best balance the nutritional components of the commodity ingredients in use at that time.
