Thank you for taking the time to visit our website. We appreciate your interest in learning more about our company.


In 1956, the Company was formed as a sales representative agency for manufacturers 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. As the industry grew, the level of nutrition improved as these feeds and foods became more sophisticated, and Bill Barr & Company expanded the level of service to customers to include the distribution of critical ingredients as well as their representation.

Bill Barr & Company is proud to have been on the leading edge of new ingredients and remains so today. The company provides only the highest quality ingredients that add value to their customer’s formulations. These ingredients are nutritionally sound, nutritionally based and manufactured to exacting quality standards. All manufacturers represented by Bill Barr & Company share this same commitment to quality and exceptional customer service.


Bill Barr and Company is always looking for ways to better serve their customers. We were one of the first companies to represent amino acid manufacturers in their bid to balance the protein requirements as well as produce lean meat more efficiently. Ajinomoto, a manufacturer represented since 1970, was the pioneer in the commercial use of L-Lysine, a common ingredient by today’s standards.  Bill Barr and Company is more recently working to insure the maximum savings possible with the successful formulation of Ajinomoto Heartland’s Lysine, Threonine, Tryptophan and Valine.

A few other pioneering efforts in order to better serve the growing needs of their customer’s:

  • The use of magnesium oxide as a buffer, an essential nutrient in the protection against grass tetany and as a process enhancer.
  • The use of Taurine in cat diets as an essential amino acid for pets, eliminating the need for liquid fish soluble in diets.
  • The commercial use of Potassium Chloride as a source of Potassium in high grain feedlot rations and an important electrolyte in feeds and pet foods.
  • The use of premium flaxseed as an outstanding source of Omega-3 fatty acids in diets.
  • The use of Sodium Sesquicarbonate (S-CARB) as a buffer and electrolyte in cattle and poultry diets.
  • The use of highly digestible alternative protein sources for pets.
