Fattening for Market 409 
STANDARD FEEDS 
At the beginning of fattening average pigs are given 
about four and one-half pounds of feed for each 100 
pounds of live weight. This is increased until within a 
week the pigs are receiving all they will clean up in thirty 
minutes. If they are to be fed on the self-feeder, a little 
larger increase is given before turning them to the feeder. 
The basis of the fattening ration must in all cases be one 
of the cereals. As proven by many tests at the Oregon 
Experiment Station, corn, wheat, and barley have about 
the same feeding value, pound for pound. The choice 
between these must, therefore, be determined by their 
cost, the preference always being for the one that can 
be grown or purchased the cheapest. Speltz, emmer, 
kafir, and milo maize are suitable for fattening, but should 
be supplemented a little more liberally with protein feeds 
than corn, wheat, or barley, and even then not quite as 
good gains will be secured with a given quantity of feed. 
When purchased, these grains should be procured at one- 
fifth to one-fourth less a ton than wheat. Oats, rye, and 
speltz should only be fed with other cereals and supple- 
mented with protein feeds. A grain ration consisting of 
one-third oats or speltz and two-thirds wheat, barley, or 
corn may be expected to yield practically as much gain 
as a ration of wheat or barley alone, providing that in 
each case they are properly supplemented. Rye gives 
better results in connection with oats or barley than with 
wheat or corn. If rye is cheaper in price than barley, 
one-third of the grain ration may be rye. 
Canada field peas are adapted to much of the semi- 
arid regions lying either side of the Rockies. Any quan- 
tity of pea-meal up to two-thirds of the ration will save
