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 paris; barley, one part; shorts, one part. 
Lot 2. Corn. 
Lot. 3: 
Lot 4. Corn, nine parts; Swift’s tankage, one part. 
Corn, nine parts; Armour’s meat meal, 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; corn alone, 1.8 pounds. 
The feed consumed per 100 pounds gain is shown in the 
following table:
