mixtures for poultry should contain. relatively small proportions of such feeds as 
alfalfa meal, wheat bran, and wheat middlings. It is believed that rations that carry 
a low percentage of fiber wil give the best results. 
The highest percentage of digestion of protein is that of meat and bone meal with 
fish meal coming a close second, digester tankage ranks third, and blood meal fourth, 
fat extracted soybean fifth, and dried buttermilk sixth. Fowls assimilate best the 
protein of animal products 
In our tests, numbering 13 in all, the protein of corn meal either bolted or unbolted 
is digested to better advantage than that of whole corn. 
Our tests show 88.18 percent nitrogen-free-extract digested in oats in six tests as 
compared to sixty-nine by other authors with the exception of Bartlett who gives 
90.10 percent. Our hulled oats experiment, five tests, shows 86.22 percent d gested 
by fowls. The feeds high in nitrogen-free-extract can well be used to make up the 
starch or carbohydrate part of our poultry feeds. Such feeds are corn, wheat, oats, 
and kafir corn. Kafir corn makes an excellent substitute for wheat and should be 
used more if the price permits. . 
With the exception of wheat and wheat middlings the digestion of fat or ether 
extract is no more variable than for other feeds. Barley is only model ately low, 
having 64.36 percent of the fat digestible.
