PREPARATION OF FEED 215 



will automatically deliver, or keep constantly before the pigs, 

 a certain amount of dry feed in troughs. 



The Dominion Experimental Farms, Canada, claim the fol- 

 lowing advantages for the self-feeder: 



It saves 60 per cent, of the labor, reduces waste of feed, pre- 

 vents digestive troubles, economizes trough space, and gives all 

 the pigs an equal chance. 



The Missouri Experimental Station concludes that hogs fed 

 with a self-feeder gain more rapidly than when h^nd-f ed. 



When each feed is placed in a separate feeder the hogs will 

 choose the different feeds so that the gains will be rapid and 

 relatively economical. 



The Kansas Experimental Station also reports strongly in 

 favor of the self-feeder. 



Farmers' Bulletin 906 of the United States Department of 

 Agriculture presents a strong case in favor of the self-feeder 

 for hogs. 



The Dominion Experimental Farms state that the feeder 

 may be used with all classes of fattening hogs and for young 

 breeding sows during their first fall and winter. The self-feeder 

 is not recommended for mature breeding stock, unless bulky 

 foods, such as ground alfalfa, etc., are used. 



The self-feeder is especially suitable for outdoor or pasture 

 feeding, but may be adapted to pen or yard feeding in winter, 

 provided it is placed where snow and ice will not interfere with 

 the troughs. 



Construction of Self-feeder. Base. The feeder should 

 rest upon two pieces, 2 inches by 4 inches, running lengthwise, 

 placed flat. These may act as runners. On these lay pieces of 

 2 inches by -i inches to carry the structure. 



Sides. Make the sides of 2 inches by 3 inches sheathed 

 inside by %-inch dressed lumber, as shown.
