forty-eight pounds of carbohydrates and fat. Feeds 

 containing a greater proportion of protein than 

 called for by these standards can be fed, because pro- 

 tein can take the place of the other materials. Carbo- 

 hydrates and fat cannot take the place of protein, 

 however, and no matter in how large quantities they 

 may be fed, if protein is lacking the growth or gain 

 will be reduced. 



"The weak point in feeding is that the average 

 rations are greatly deficient in protein, and have too 

 much carbohydrates and fat. Every feeder knows 

 that good pasture produces rapid growth, good gains, 

 and abundant milk yields. It furnishes nutriment in 

 the proportion of three pounds of protein, twelve 

 pounds of carbohydrates, and one-half pound of fat. 

 The proportions in some of our feeds, in pounds per 

 loo pounds of feed, are as follows: 



Protein. Carbohydrates. Fat, 



Corn 7.8 66.7 1.6 



Kafir-corn 7.8 57.1 2.7 



Prairie hay 3.5 41.8 1,4 



Corn fodder 2.0 33.2 0.6 



Sorghum hay 2.4 40.6 1.2 



' ' It will be seen that none of these feeds contain a 

 sufficient proportion of protein to secure best results, 

 and all combinations of these feeds will have the same 

 defea. 



' ' Some feeds have too great a proportion of protein 

 to be fed alone, as shown below, the figures indicating 

 pounds per 100 pounds of feed:
