202 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



pensive than those obtained from any of the other rations. 

 The tests during two winters showed that a fattening ration 

 fehould contain less than half alfalfa, but a ration of half 

 alfalfa and half corn was found quite satisfactory for wintering 

 brood sows. 



(2) When half the ration consisted of alfalfa, alfalfa meal 

 gave faster gains with less grain than chopped alfalfa, but the 

 difference was not enough to pay for the extra cost of the 

 alfalfa meal.

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.) 



(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.
