Pork Production 



No forage was supplied in either of these comparisons. 

 The pigs in the first Minnesota experiment averaged 147 

 pounds, and in the second 125 pounds, when they went 

 into the experiments. In both the Iowa tests, the pigs 

 weighed at the beginning approximately 69 pounds. The 

 Minnesota pigs were turned in November 29 and 9 

 respectively in the two experiments, and the Iowa pigs, 

 September 19. 



The averaged results of these four comparisons show 

 the reliability and economy of the hogging-down system 

 of feeding corn when well managed. With but one 

 exception, namely, the first Iowa experiment, the pigs 

 harvesting their own corn gained faster than did those 

 fed in the usual way. In this comparison no supplement 

 of any kind was fed. The authors of the experiment 

 attributed the exceptionally poor gains made in this lot 

 to the fact that the poor appetites of the pigs made it 

 necessary to continue them in the field until December 

 4th to get them to clean up, at which time the weather 

 had become bad and the field muddy.
