1LabDiets contained crude ingredients and micronutrients similar to AIN-76A (http://www.testdiet.com/). Other diets were defined diets containing AIN-76A mineral and vitamin mix. All defined diets contained ~0.002% ethoxyquin as an antioxidant, and had an adequate amount (0.2%) of choline bitartrate or choline chloride. 2Protein, carbohydrate, and fat in Brewer’s yeast are not included in other contents. 3All % content is by weight. 4A dash means not present. 5CHO means carbohydrate, and Corn means corn starch.
