York Ag traces its roots to Dale Anderson and Arthur McAlister, who turned their regional limestone experience toward animal nutrition and began developing a calcium alternative for the egg industry in the mid-1980s. Now in its third generation under Bill Achor, the Manheim company helps feed manufacturers and livestock producers solve nutritional challenges by identifying and sourcing specialized ingredients, including its long-standing YORK CALCIUM CHIPS® product. Its work remains shaped by a practical, collaborative approach to animal well-being rather than a one-size-fits-all catalog.
