Results from poultry feeding experiments.—In earlier poultry 
feeding experiments at this Station the desirability of sometimes 
using animal food with the standard grains has been plainly 
shown. For growing ducklings this was especially evident. 
Knowing the general character of the food for wild birds it is to 
be expected that the young of domestic fowls might subsist to 
advantage largely upon fresh animal food; but the animal foods 
of commerce have been subjected to various processes for their 
separation or preservation and are most convenient for use in the 
dried form. 
Very few data existed concerning the amount or proportion of 
commercial animal food that could be efficiently or profitably 
used. To partly supply this lack, feeding experiments have been 
made, results from some of which are reported in a recent bul- 
let'in. 
Rations in which these foods supplied 94 per ct. of the total 
dry matter and 98 per ct. of the protein were fed to ducklings 
without any apparent ill effects. 
During the first few weeks growth was more rapid, and equal 
growth made from less food (even at a lower cost for food) 
under a ration in which 60 per ct. of the protein was obtained 
from animal food than under rations having respectively 20, 40 
and 80 per ct. of the protein derived from this source. 
Later growth was made at somewhat more economical expendi- 
ture of food under the “20 per ct. ration,” but was slower. 
Under the rations coutaining larger proportions of animal food, 
marketable size was reached about two weeks sooner. 
Results on the whole favored the use, for the first few weeks, 
of the ration in which 60 per ct. of the protein came from 
animal food, and later those containing larger and increasing 
proportions of grain foods.
