Ten female and 230 male kits were used to study the need for pantothenic acid by growing mink. Three trials were conducted using purified diets with ad libitum and equalized paired-feeding techniques. The minimal pantothenic requirement for growth was found to be 5 mg of calcium pantothenate/kg of diet, whereas 8 mg/kg of diet were required for optimal performance. Anorexia and reduced serum cholesterol were early responses to hypovitaminosis. The gross pathological findings were diarrhea, cachexia, and dehydration with hemorrhagic gastric ulcers and specific starvation lesions.
2 These studies were supported in part by a grant from the Mink Farmers' Research Foundation, Milwaukee, Wisconsin.
