142 Pork Production 



agricultural press to the merits of forage crops as means 

 of balancing the corn ration and improving present 

 methods of pork production has had the effect of stimu- 

 lating interest and inquiry into the possibilities of these 

 crops and the place which they should occupy in a well- 

 organized plan of management for the hog farm. In the 

 following pages the results of experimental feeding tests 

 are presented together with the teachings which a careful 

 study of these results seems to justify. 



Dry lot versus forage feeding. 



In Table XXXIII are presented the summarized results 

 of eleven experiments 1 in which the dry lot method of 

 feeding pigs was compared with that of feeding on forage. 

 In all cases, the experiments began soon after the pigs 

 were weaned and continued throughout most of the 

 summer, covering an average period of 104 days, 

 Timothy was used in three of the tests, rape in four, 

 alfalfa in two, a mixture of rape, Canada field peas and 

 oats in one, and soybeans in one. In each experiment the 

 same grain rations were fed in the dry lot and on forage, 

 except in one of the Iowa tests when the proportion of 

 meat-meal to corn fed on forage was slightly less than that 

 fed in the dry lot. With but one exception, the pigs in 

 both the dry and forage lots were full fed ; i.e. given all 

 the grain they would eat. It should also be noted that 

 in every comparison the ration fed in the dry lot was 

 practically a balanced one. 



In no case is there an experiment included in which corn 

 alone was fed. In other words, each experiment in- 

 cluded in this summary is a test of the balanced ration
