SUPPLEMENTARY FEEDS WITH CORN 161 



Com was valued at $18.00 per ton, tankage at $40.00 per 

 ton, and old process linseed meal at $30.00 per ton. 



In two tests linseed meal proved slightly more economical 

 than tankage, and in the other two tankage had a fairly marked 

 advantage. 



The averages of the four tests show the feed requirements 

 and cost of 100 pounds of gain to be as follows : 



Corn meal and tankage: 370 lbs. corn, 24.5 lbs. tankage, costing $3.82. 

 Corn meal and linseed meal: 363.6 lbs. corn, 46.2 lbs. linseed meal, 

 costing $3.96. 



Conclusions. — It is noted in the summary that hogs fed 

 on a ration of corn meal and tankage consume more feed and 

 make more rapid gains than hogs fed a ration of com meal and 

 linseed meal. 



Also, that a ration of com meal and tankage gives a better 

 finish than one of com meal and linseed meal. 



Soy-Bean Meal vs. Linseed Meal. — ^Indiana also reports 

 two tests comparing soy-bean meal with linseed meal as sup- 

 plements to com. 



In the first test, 5 parts of com meal were fed with 1 part 

 of linseed meal or soy-bean meal. In the second test, 8 parts of 

 com meal were fed with 1 part of linseed meal, and 7 parts of 

 corn meal with 1 part of soy-bean meal. 



Linseed meal and soy-bean meal are both valued at $30.00 

 per ton, and corn meal at $18.00 per ton. 



On an average of the results of the two trials, it required 

 for 100 pounds of gain : 



Com meal and linseed meal, 378 pounds, costing $3.71. 



Com meal and soy-bean meal, 360 pounds, costing $3.55. 



The percentage of protein in linseed meal and soy-bean meal 

 is very similar, and, though Boy-bean meal showed an advantage
