(3) The average of four tests with 160 pigs showed that 

 rations containing one-fourth alfalfa produced slower gains 

 than a ration of corn alone, or of 9 parts of corn and 1 part 

 of alfalfa. It would seem that a ration containing one-fourth 

 alfalfa is not as satisfactory for fattening hogs as a ration of 

 corn alone, or a ration containing a larger proportion of corn 

 and a smaller proportion of alfalfa. 



(4) Alfalfa meal proved more satisfactory than chopped 

 alfalfa when the ration consisted of one part of alfalfa to three 

 parts of corn.

 alfalfa rack. 



The rack is made of l"x 4" stuff. It is 3 feet high, 6 feet long, and 16 inches wide. The 

 top is open, the ends solid, and the four-inch slats have four-inch spaces between them. 

 The trough along each side is 4 inches deep, and extends 7 inches beyond the bottom of the 

 rack. (Col. Bui. 146.) 



(5) In three tests with 90 pigs, a ration containing 9 parts 

 of corn to 1 part of alfalfa .proved more profitable than corn 

 alone. 



(6) When the alfalfa comprised only one-tenth of the ration, 

 chopped alfalfa and alfalfa meal gave almost the same gains, 

 hut the chopped alfalfa proved more profitable owing to its 

 lower cost, 



(Y) In three tests with 90 hogs, the feeding of corn with 

 alfalfa hay in a rack gave very similar returns to feeding 9 

 parts of corn mixed with 1 part of chopped alfalfa, with the 

 difference in favor of rack feeding.
