Choosing a Forage Crop 



177 



450 pounds of grain for each 100 pounds of gain may, 

 therefore, be considered as fairly satisfactory. 



Although timothy is not a valuable forage crop for 

 pigs, it is sometimes profitable to make use of it for this 

 purpose. It is very succulent and palatable, but low in 

 its content of protein. It supplies considerably less 

 protein in proportion to its carbohydrates than does 

 either rye or blue-grass. As shown by experiments con- 

 ducted at the Iowa Station ^ in 1906, the feeding of pigs on 

 timothy gave fairly satisfactory results when compared 

 with dry lot feeding. In Table L are given the averages 

 for four lots on timothy and for comparable lots fed in 

 the dry yard. The pigs in both the dry and forage lots 

 were fed balanced rations.

SORGHUM — CANE 



Sorghum is used more or less extensively as a forage 

 for swine in the southern part of the corn-belt and farther 

 south and in the semi-arid regions of the Southwest. Its 

 chief merit is its ability to furnish a heavy tonnage of 

 succulent feed in a dry hot season. It should be pas-
