In order that the deficiencies found throughout the past five years may be compared, the following table (No. V), has been prepared. It will be noticed that with one exception in the case of protein alone, the number of deficiencies was less during 1910 than during any previous year. Feeding stuffs may be classed according to their content of crude protein into five classes. The percentage of protein is highest in cottonseed meals and decreases to that found in such feeds as whole grains ground together, and oat feeds composed of oat by-products. The classification here presented was suggested by Jordan and Jenter,* as follows: Class 1. 30 per cent. to 45 per cent. protein. Class 2. 20 per cent. to 30 per cent. protein. 8 per cent. to 14 per cent. protein. 5 per cent. to 8 per cent. protein. The hays and other coarse fodders may be classed in the fourth group, and the animal by-products are in a class by themselves. In the following table (No. VI), a large number of the brands of feeding stuffs received are tabulated according to the above classifi cation. *Bul. 166, New York Experiment Station, Geneva. AVERAGE PARTIAL COMPOSITION AND RETAIL PRICE. In the following table (No. VI), the average partial composition and retail price of a number of the feeding stuffs analyzed during 1910 are given. They are arranged in classes according to their content of crude protein. This table will be of interest to those who prepare their own rations for feeding purposes, as it will give some idea as to the average content of protein, fat and fiber found in the brands of feeding stuffs analyzed during 1910, together with the average retail price.
