FEEDING SWINE

has been shown, however, that no decided advantage is secured by 

 this method. The average results of twelve trials conducted at 

 eight different stations, as shown by Rommel (loc. cit.), came as 

 follows: Feed required per 100 pounds gain, dry feed 444 pounds, 

 wet feed 434 pounds, a difference of 2 per cent in favor of the latter 

 feed. The pigs, in general, ate more soaked or wet feed than dry 

 feed, and often made slightly better gains on the former feed, but 

 the returns per unit of feed eaten were not, as we have seen, appre- 

 ciably improved by the method of preparation; nor has it been 

 shown that the amount of water fed in the slop of pigs has any 

 material effect on the gains made or on the utilization of the feed. 7 



Swine Feeds. The various feeds used in feeding swine have 

 been previously discussed, and we shall consider here only a few 

 of the main swine feeds, especially with reference to feeding prob- 

 lems in different sections of the country.
