except the last two weeks, was over fifty-one per cent. of the total 
food. The capons in lot “C” were of Indian: Game-Buff Cochin 
cross removed from another lot with which they had been fed 
until in December. With them skim-milk constituted fifty-eight 
per cent. of the total food and over twelve per cent. of the water- 
free food during the few weeks that they were fed. The Light 
Brahma capons in lot “D” which also were fed until December 
in a mixed lot, had fifty-four per cent. of their ration skim-milk. 
With the smaller lots designated “E,”.“F,” “G” and “H,” the 
rations contained also a large proportion of skim-milk, varying 
at different times from forty-two to sixty-nine per cent., and, 
- except with lot “HE,” generally being over sixty per cent. of the 
total food. 
The gain or loss for lot “G” during the four. weeks recorded. 
is so small that the ration fed may be considered as entirely a 
maintenance ration, and gives the amount of water-free food per 
day for each one pound of live weight fed as approximately one- 
half ounce. The cost of this ration per day for each 100 pounds 
live weight of fowls fed would be five cents. 
The B. P. Rock cockerels were caponized at the average weight 
of 2.7 pounds, and lost from fasting and the operation ten per 
cent. but gained during the week in which they were capon- 
ized 6.6 per cent. The B. Langshan capons were caponized at 
the average weight of 3.9 pounds and lost 12.2 per cent., 
but lost during the week only an average of .5 per cent. The 
Lt. Brahmas were caponized at average weight of 4.8 pounds and 
lost 11.9 per cent., the loss for the week being 8.7 per cent. 
In the tables containing the average results for periods of two 
weeks the figures giving the “ratio of protein to total carbo- 
hydrates in food” are not intended for the usually given “nutri- 
tive ratios,” and no attempt was made at determining the 
digestibility of these foods with fowls. The ratio simply gives 
the proportion, in the total ration, of crude protein to the total 
carbohydrates, the fats not multiplied. 
The figures under the headings “ Pounds of water-free food for 
each one pound gain in weight” and “Cost of food for each one
