Emmer, usually called speltz, is a drought resisting grain 
crop, and is a good feed for horses, cattle and sheep, but a poor hog 
feed, as it has too much husk. 
Milo Maize is one of the best drought resisting crops, and Is 
well adapted as a grain crop for hog raising for the Plains. It 
should be either ground or soaked. One hundred pounds of milo 
maize is equal to ninety pounds of corn for fattening hogs. The 
average amount of pork that can be produced an acre per year is 
much greater under dry land farming with milo maize than with 
com. Milo maize is constipating, and some laxative feed should 
be given with it, such as alfalfa hay, fiax seed, in small quantities, 
sorghum fodder cured green, tankage or bran. 
Rye makes a good feed for growing hogs. It has the same 
defects as wheat and should be prepared and used in the same way 
as wheat. 
Tankage consists of the scraps and trimmings of meat and 
bone from the packing houses, cooked, the fat removed and the 
residue dried and ground. It is rich in protein and in mineral 
matter, and should be fed in small quantities mixed with 
grain. It is of special value when fed with starchy grains, such 
as barley, corn and milo maize, and when fed with these grains in 
the ratio of 95 pounds of grain to 5 pounds of tankage, will reduce- 
the amount of feed required to make 100 pounds of increase in 
live weight from 20 to 35 per cent. Tankage-fed hogs finish well,, 
the flesh is fine and the hair and skin thrifty. 
Tankage is the best substitute for skim milk for feeding pigs 
just weaned, and should form one-fifth of the total weight of 
grain fed for a short period, and then one-tenth, until they get to- 
eating alfalfa well. 
Skim Milk .—No other feed is equal to milk for feeding pigs 
just weaned. It makes the change from mother’s milk easier. 
Whole milk is good, but as butter fat in Colorado is worth from 
$400 to $960 a ton, it is expensive pig feed. Skim milk should 
be fed sweet and mixed with the grain. It has the greatest value 
when not over three pounds of milk are fed for each pound of 
grain, and when fed in this ratio, from 325 to 475 pounds of skim 
milk have a feeding value equal to 100 pounds of grain for feed¬ 
ing hogs. 
Skim milk is a valuable feed for fattening hogs, and it im¬ 
proves the quality of the flesh. The high quality of both Canadian 
and Danish bacon is undoubtedly due. in considerable measure, to 
the feeding of skim milk or buttermilk to hogs throughout their 
lives. Milk is an easily digested feed, it aids in the digestion of 
the grain fed with it; it is appetizing and healthful, and fed to the 
growing pig promotes development of muscle and bone.
