36 Rerort oF DEPARYMENT OF ANIMAL HUSBANDRY OF THE 
Owing to the higher price for the by-product called “ milk albu- 
men” the ration was less profitable, the average cost of growth 
exceeding by over 27 per ct. that for Lot I. 
EXPERIMENT WITH CHICKS. 
CONDITIONS. 
At another time four similar lots of chicks were fed for two 
months on rations in which most of the protein was derived from 
highly nitrogenous by-products. For two lots there was added 
to the basal ration animal food. Except for a little bone meal 
fed to one lot the two others had no food of animal origin. The 
added food supplied from about one-quarter to one-third of the 
total dry matter of the ration and about half of the total protein. 
The experimental feeding began when the chicks were two weeks 
old. 
FOODS AND RATIONS. 
Each lot was fed cracked corn, wheat, green alfalfa and two 
ground grain mixtures. One mixture, “T,’ consisted of two 
parts by weight of corn meal and one part each of wheat bran 
and wheat middlings. Another mixture, “ V,” consisted of four 
parts corn meal, three parts each of wheat middlings, Chicago 
gluten meal, germ gluten meal and Atlas “gluten meal” and 
two parts each of O. P. linseed meal and wheat bran. Besides 
these foods Lot IV, was fed animal meal, Lot V, “ milk albumen ” 
(a by-product from milk sugar factories), Lot VI, Chicago gluten 
meal and later cream gluten meal, and Lot VII ground bone with 
either Chicago gluten meal or cream gluten meal. The accom- 
panying table shows the average composition of each food.
