The first table shows the amounts of crude materials in 100 

 pounds of each of the two hays; the second table, the amounts 

 that are digestible; and it will be observed that the Lespedeza 

 hay shows over 100 percent more digestible protein than is 

 found in the Timothy hay. 



Again, owing to the higher protein content of Lespedeza hay, 

 it requires a lesser amount of it to balance a ration with such 

 grains as oats or corn. 



For example, the average daily requirement in digestible 

 protein, carbohydrates and fat, or total carbohydrates, if we re- 

 duce the fat to its starch equivalent and include it as carbohy- 

 drates, for a horse or mule, weighing 1,000 Ibs., and doing hard 

 work, is about as follows, which is spoken of as the feeding 

 standard for such an animal : 



Protein (Ibs.) Total Carbohydrates (Ibs.) 

 2.30 14.30 



In other words, in the day's ration of grain and hay, which 

 should amount to approximately 23.00 Ibs., not including any 

 moisture, there should be 2.30 Ibs. of digestible protein and 14.30 

 Ibs. of digestible total carbohydrates. 



Suppose, then, that we want to compound a ration, that will 

 approximate the above standard, out of shelled corn and Timothy 

 hay: 



Digestible 



Total 



Dry Matter Protein Carbohydrates 

 Ibs. Ibs. Ibs. Ibs. 



15 Shelled corn 13.35 1.18 3 1.46 



36 Timothy hay 31.32 1.01 16.87 



44.67 2.19 28.33 



By comparing this ration with the standard requirements, 

 it will be noted that, in order to approximate the necessary 

 amount of protein, alone, 36 Ibs. of Timothy hay would have to 

 be fed, which would not only give an excess of over 21 Ibs. of 

 dry matter to be digested by the animal, which would hardly be
