PREPARATION OF FEED 215 
will automatically deliver, or keep constantly before the pigs, 
acertain 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, reduccs waste of feed, pre- 
vents digestive troubles, economizes trough space, and gives all 
the pigs an equal chance, 
The Mirsouri Experimental Station concludes that hogs fed 
with a self-teeder gain more rapidly than when hand-fed. 
Wheu cach 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 Ntates Department of 
Agriculture presents a strong case in favor of the self-fceder 
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, ctc., are used. 
The self-feedex 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 hy + inches, running lengthwise, 
placed flat. These may act as runners. On these lay pieces of 
2 inches by + inches to carry the structure. 
Sides.—Make the sides of 2 inches by 3 inches sheathed 
inside by 7%-inch dressed lumber, as shown.
