The only exception to this rule is that it may be 

 advisable sometimes to allow them to go to the sheds

 alfalfa field as soon as they are willing to leave the 

 shade in the afternoon. 



Thus managed, the writer in an experience of sev-

 partly attributable to bloat. 



Varying Practice. Regions differ as regards the

 to be impossible to pasture sheep on it at all. In 

 other places it is an easy thing to accomplish safely. 



In Arizona and New Mexico there is now a large 

 use of alfalfa pasture for lambing ewes in spring-
