 alfalfa is by far the most important. In addition to this 

 there are several grasses that are perennial. Also, there 

 are several plants that are not perennial, but they re-

 Among such plants is bur clover. The chief value in 

 perennials is that they require less work in reseedmg each 

 year. A permanent pasture, such as Bermuda, is not 

 difficult to obtain, and it is a sure crop. Usually peren- 

 nials make a surer crop than the annuals, but will not 

 yield quite so heavily. 



Annual grazing crops. — Most of the swine-grazing 

 crops in use are annuals. They have their chief value in 

 that two crops can be planted and harvested in the same 

 field in a season. Most hog-grazing crops are either 

 planted in the early spring or early fall. It is almost 

 impossible to arrange a system of crop rotation suitable 

 for hog grazing without the annuals. Among them are
