 of live weight with good results. 



139. Soybean Meal. Soybean meal is highly nitrogen- 

 ous, containing about 33.5 per cent of protein which shows 

 a digestibility of 87 per cent. It forms a better feed after 

 the oil is expressed than when the whole bean is ground and 

 fed. 



140. Peanuts. Peanuts run high in both protein and fat, 

 and form an excellent source of feed for hogs. Peanuts 

 yield about 40 bushels per acre, and are best harvested by 

 the hogs. Unless the fattening is completed by feeding 

 corn, the lard will not solidify at ordinary temperatures. 

 When the oil is extracted, the peanut meal may be used to 

 some e.xtent as a feed for stock. This meal contains the 

 highest protein content of any vegetable material about 

 47 per cent. 



3. THE ROUGHAGES 



141. Timothy. Timothy is the most popular hay for 

 city markets, and serves well as a roughage along with such a 

 concentrate as oats; but under farm conditions other hays 

 are more cheaply grown, because they yield more heavily. 

 The early cut timothy hay contains more protein in propor- 

 tion to the carbohydrates present, and therefore is well 

 suited to the requirements of dairy cows and young and 

 growing stock. The late cut hay is better for horses and for 

 fattening cattle. Late cutting also gives a better yield. On 

 account of its quality, timothy is highly valued for horses, 

 but it does not contain a large amount of digestible nutrients. 

 Timothy is not an economical feed for fattening cattle nor 

 for dairy cows ; in fact, it is most valuable as a roughage for 

 driving, saddle, and race horses. From the farmer's view- 

 point, the chief value of timothy lies in the fact that it is an 

 easily marketed hay.
