Such mixtures may be divided into two classes, (a) the ready- 

 rations containing from 15 to 26 per cent of protein and (b) the 

 great variety of stock and horse feeds with less than 15 per cent 

 protein. 



In order to get at their approximate values I would make the fol- 

 lowing suggestions. First note their guarantees and if it is desired 

 to use them as a complete ration, buy those having at least 18 

 per cent of total protein and the least amount of fiber. Note also 

 the price as compared with a ration that you can prepare from the 

 standard articles in the local markets. 



If stock and horse feeds are desired, buy one of those which is 

 free from a musty odor and which has the least percentage of fiber. 

 Most of these mixtures contain oat and other grain hulls, and some 

 contain ground weed seeds, the hulls of which are quite tough and 

 indigestible. The higher the percentage of fiber such feeds show, 

 the larger the amount of grain hulls and the hke they contain.
