In computing the cost, corn meal was valued at 71.4 cents 
per hundred-weight, and Armour’s meat meal at $37.00 per 
ton. 
It will be noted that the lot receiving 10 parts corn to 1 
part meat meal made the most rapid and the cheapest gains. 
As in the first experiment, the hogs fed corn alone made 
the slowest and most expensive gains. 
The report of the experiment states: ‘The pigs in all 
lots were uniformly very fat, and the difference in gain be- 
tween the lots getting meat meal and the one getting corn 
alone seems to have been mostly in growth, although the meat 
meal pigs showed smoother, glossier hair.” 
Meat Meal, Tankage, and Shorts.—A third experiment of 
the Iowa Experiment Station had for its object the comparison 
of Armour’s meat meal and Swift’s digester tankage with 
shorts, as supplements to a corn ration with young growing 
pigs. As the pigs were young, averaging 60 pounds in weight, 
it was not thought advisable to feed any of them corn alone 
in dry lots. The lots that were fed corn as the only concentrate 
were pastured on timothy or clover pasture. Altogether, 100 
pigs were used, and divided into ten groups of ten pigs each. 
Tankage and meat meal were fed in the proportion of one 
part tankage or meat meal to five parts corn meal.
