The use of the self-feeder.—While the use of the self-feeder in pork production is a new idea, it is one of themost economical, practical, labor-saving and efficientmethods we can employ, especially where full feeding isdesired. The importance of the self-feeder is largely theresult of efforts made by Mr. John M. Evvard of theIowa Station, who has secured some quite favorableresults. It can be safely stated that the self-feeder haspassed the experimental stage, and its use is to be gener-ally recommended in pork production. Earlier maturity, with the resulting saving in feed and labor, is madepossible.
