The German feeding standard for a milch cow calls for pounds total nutritive substance in the digestible portion of her food, these nutritive substances to be proportioned as follows: Protein, pounds; carbohydrates, 1" pounds, and ether extract, or fat, pound. This gives a nutritive ratio of 1 In other words, to every pound of protein there are pounds of nitrogenous materials. The nutritive ratio may be determined by multi- plying the ether extract by , adding to this product the carbohydrates, and dividing by the protein. Each pound of fat or ether extract is assumed to have a feeding equivalent of pounds carbohydrates. The author has been unable to find the reports of any experiments determining the amounts of these materials necessar}- for fowls. For want of definite information on several points he is unable to do the subject justice, but with many apologies and a few misgivings, he will attempt to formulate a ration which shall be practicable for the farmer. It is usual to feed a ration of soft foods in the morning, with a whole grain ration at night. We will suppose to have our choice of the following feed stuffs: Bran, corn meal. For convenience we will mix 250 pounds of soft food at a time, selecting as an experimental ration 100 pounds bran, 50 pounds com meal, 50 pounds ground oats, 25 pounds cottonseed meal, 25 pounds beef and blood meal (assuming the latter to be composed of equal parts of blood and meat scraps.; These quantities, by reference to the foregoing tables, are seen to contain the following amounts of digestible nutrients: Protein, 45 34 pounds; carbohydrates, pounds; tcher extract of fat, pounds.
