SUPPLEMENTARY FEEDS WITH CORN 



155 



In computing the cost, com 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 com 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 com 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 com 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 com meal.
