Preparation of Feeds 349 



ing of any class of swine when rapid gains are not desired. 

 The question of the adaptabihty of the self-feeder is 

 largely one of the advisability of full feeding. 



2. For satisfactory results in self-feeding, it is neces- 

 sary that both carbonaceous and protein feeds be sup- 

 plied, and that these feeds be palatable. If the carbo- 

 hydrate feed is not well liked and the protein is expensive, 

 it will be best to mix the two in the proper proportion, 

 thus eliminating the "free-choice" feature. 



3. The self-feeder does not relieve one of all the work 

 or responsibility in feeding. The "feeder" should be 

 visited daily. The spaces which regulate the flow of 

 feed should be carefully adjusted so that no feed is wasted, 

 all the compartments of the feeder must be kept open and 

 feeding all the time, and the caked mud should be re- 

 moved frequently from the troughs. The feeder should 

 not be set in a mud hole, but rather on a concrete or board 

 floor ; and it should be located in the shade in summer 

 and a warm protected place in winter. To make the 

 self-feeding system for fattening pigs complete and most 

 eflacient, a feeder containing salt, charcoal, and wood- 

 ashes or lime should be provided, especially when the pigs 

 are confined to the dry lot.
