RESULTS OF EXPERIMENTS IN SWINE FEEDING 



Gate.*- Two arrangements of the feed-gate are shown. This 

 is the important part of the feeder. 



Make the iron bands (two on each side) connecting the con- 

 trol slide at the bottom, with the thumbscrew at the top, of light 

 strap-iron one-eighth inch thick by one inch wide. When the 

 meal ceases to flow, the pigs naturally root or nose toward the 

 source of supply, and being able to move this flexible slide,, which

in turn presses upon and breaks the meal blockade they are 

 rarely left with a " dead " self-feeder. To prevent the pigs 

 forcing the board too far in, it is, of course, necessary to place 

 a cleat inside at either end of each slide. Allow about y-inch 

 play between the slide and the cleat. 



The second arrangement shown is simple, consisting of a 

 section of the gate hinging inward. This the pigs may root 

 against, causing it to break any meal stoppage. Possibly the first 

 described arangement will be found most satisfactory. 



* To ensure the constant feeding of the meal, some means of agitation 

 is necessary. Otherwise the contents will block close to the bottom.
