SUPPLEMENTARY FEEDS WITH CORN 153 



beans have not made a very good showing, because, in most 

 localities, wheat middlings would be very much cheaper. The 

 influence upon the texture and firmness of the meat is also 

 worthy of consideration. 



Barley, Shorts, Meat Meal, and Tankage The Iowa Ex- 

 periment Station reports an experiment with forty-eight well- 

 grown hogs divided into four lots. The rations of the different 

 lots were as follows: 



Lot 1. Corn, two parts; barley, one part; shorts, one part. 



Lot 2. Com. 



Lot 3'. Com, nine parts ; Armour's meat meal, one part. 



Lot 4. Corn, nine parts ; Swift's tankage, one part. 



Meat meal and tankage are by-products of the packing 

 house, and are both very rich in protein. The meat meal used 

 in this experiment contained 66.36 per cent of protein, and 

 the tankage 53.54 per cent. Such highly concentrated feeds 

 must be used in small quantities. The hogs averaged 218 

 pounds each at the commencement of the trial, which lasted 

 thirty-two days. 



The average daily gain per hog in each group was as 

 follows: Meat meal, 2.6 pounds; tankage, 2.3 pounds; barley 

 and shorts, 2.2 pounds; com alone, 1.8 pounds. 



The feed consumed per 100 pounds gain is shown in the 

 following table:
