In addition to the above amount aetualh^ consumed, 

 32 per cent, of the soy bean hay that was offered was 

 rejected. This rejected portion consisted of the coarse 

 stalks and some of the larger limbs. The correspond- 

 ing waste with cowi>ea hay in this test was 22 per cent, 

 of that offered. 



Soy beau hay rs. cowpea hay. 



From the above table we see that the soy beans af- 

 forded U per cent, more butter and 3| per cent, more 

 milk than an equal weight of cowpea hay actually ocn- 

 sumed. However, the greater waste or greater residue 

 with the soy bean fully counterbalances this, reducing 

 the hay of these two valuable leguminous plants to a 

 practical equality in feeding value. Soy beans are 

 worthy of more extensive cultivation in the South. Their 

 principal advantage over cowpeas consists in their easier 

 curing, erect growth, and freedom from tangling. In 

 our experiments they seem to require slightly richer soil 

 than cowpeas. 



DIGESTIBLE MATTER IN RATIONS FED. 



In the following table are given the amounts in the 

 daily rations fed of digestible dry matter; protein, or 

 "muscle formers" ; carbohydrates ( chiefly starchy ma- 

 terial) ; and fat. For comparison, the table also in- 

 cludes the figures showing what is generally regarded as 

 the normal nutritive requirement of a cow in full flow 

 of milk.
