THE IRRIGATION AGE. 



ration, corn with alfalfa hay fed in a rack, is at the top of 

 the list. The first three rations stand closely together. Corn 

 seems to have a stationary place between a ration of 10 

 parts alfalfa and 90 parts corn and a ration of 25 parts alfalfa 

 and 75 parts corn. 



With corn worth 60 cents per bushel a ration of one- 

 fourth alfalfa and three-fourths corn gives nearly the sam<: 

 profit per pig fattened as a ration of corn alone. 



Where alfalfa was fed in the rack or where chopped 

 alfalfa or alfalfa-meal were fed in the proportion of one 

 pound of alfalfa to nine pounds of corn, a pound of alfalfa 

 was worth more than a pound of corn. 



Part II gives the results of substituting other grains 

 and mill products for, a part of the corn in a ration of corn 

 and alfalfa for growing and fattening hogs. The experi- 

 ments were conducted during the summer and winter. The 

 number of pigs in each lot varied from 10 to 30. The prices 

 used in computing the results are the average prices paid 

 for the various kinds of feeds during the progress of the

experiments. The results of these tests given very briefly 

 are as follows : 



Of the many rations tried for fattening hogs, none has 

 been found the equal of corn and a small percentage of 

 alfalfa. 



Wheat gives faster gains with less grain per 100 pounds 

 of gain than corn, but the high cost of wheat makes the gains 

 from wheat more expensive than from corn. The profit per 

 pig, if fed one-half wheat and one-half corn while being 

 grown and fattened, is less than if fed corn. This is when 

 both grains are fed with alfalfa. 



A ration of barley and corn with alfalfa does not give 

 as fast gain or as much profit per hog during the growing 

 and the fattening periods as a ration of corn and alfalfa. 



The substitution of 5 parts tankage, 5 parts bone-meal, 

 or 25 parts shorts, for corn, in a ration containing 90 parts 

 corn and 10 parts chopped alfalfa, increases the cost of 

 gains and decreases the profit per pig during the fattening 

 period. 



The substitution of '2" parts emmer, 

 barley, wheat, or milo, for corn, in a 

 ration containing 90 parts corn and 10 

 parts chopped alfalfa, increases the cost 

 of gains and decreases the profit per hog 

 during the fattening period, excepting 

 emmer, which in this test only increased 

 the profit per hog. The wheat increased 

 the gains but decreased the profit. The 

 emmer also increased the gain. Barley 

 and milo decreased the gain as well as 

 the profit. Milo was worth the same 

 nrice per bushel as barley in this test. 

 The results of one test indicated that
