in the place of corn meal were the ones consuming the larger 

 amount of protein, and if it were true that any deviation from the 

 standards given in German tables is detrimental to the nutritive 

 effect of the ration, the more highly protein fed steers should 

 have made much the larger gain. This we do not find to be the 

 case. The Holstein steer eating the cotton seed meal made a 

 greater gain than the one eating corn meal, but in the case of the 

 steers of the other two breeds this order was reversed. There 

 are, however, no marked differences in the rates of growth, 

 except, possibly, with the two Holstein animals. The nutritive 

 ratio of the ration containing cotton seed meal was 1 :6.7 and of 

 the other ration made up in part of corn meal it was 1 :10. 



The figures below were reached by assuming the foods to have 

 an average composition. The coefficients of digestibility used for 

 the hay and bran, were those that have been fouud by experiments 

 at this Station, but for the corn meal and cotton seed meal they 

 were taken from the table of German coefficients. The hay was 

 assumed to be all Timothy, whereas it actually contained a very 

 small amount of Alsike clover, which would of course make the 

 nutritive ratios slightly narrower than those given, although not 

 affecting; them relativelv.
