Pork Production 



strated by the results of a practical feeding test made at 

 the Iowa Experiment Station ^ in the spring of 1906.. 

 Thirty-six shotes, averaging approximately 136 pounds, 

 were divided equally into four lots. Lot I was fed a 

 ration of straight corn-meal, and lots II, III, and IV 

 rations containing corn-meal and different proportions 

 of meat-meal. The results from the lot fed corn alone 

 and that fed ten parts of corn and one of meat-meal, by 

 weight, are here reported.

The test began on March 13 and closed June 31, 

 covering a period of 100 days. The pigs used were of 

 mixed breeding, growthy, and in rather thin flesh at the 

 beginning of the test, which accounted in part for their 

 rapid gains. They were confined to dry yards, 40 by 80 

 feet, with open sheds for shelter. Every effort was made 

 to secure uniformity in the different lots of individual 

 pigs, in the conditions of housing, and in the methods of 

 feeding employed. The number of pigs in each lot, the
