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 
should 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.

alfalfa rack. 
The rack is made of 1’x4" stuff. Itis 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. Bul. 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.
