New York AgricuntturaAL Experiment Sration. 59 
The gain in weight was.not very regular nor very great for 
either lot, although for short periods some rapid gains were made. 
Those birds (Lot A) having the animal meal ration gained in 
weight during the trial about 20 per cent more than the others. 
During the first eight weeks the consumption of food by Lot A 
was about 28 per cent greater than that of Lot B and the gain in 
weight was about 40 per cent greater. One pound gain in weight 
was made by Lot A for every 8 lbs. of water-free food consumed 
and one pound gain by Lot B for every 8.8 lbs. of water-free food. 
During the last four weeks more food was still eaten by Lot A, 
but the gain made was considerably in favor of Lot B as well as 
the cost of the gain. The gain in weight for this period, however, 
was not economically made by either lot. 
FEEDING TRIAL WITH DUCKLINGS. 
The feeding trial with the two lots of ducklings began as soon 
as they had learned to eat and was continued until growth had 
become very slow. ‘The ration for Lot A, beside the grain mix- 
ture No. described on page 48, consisted of corn meal, ground 
oats and animal meal besides a little skim milk, curd and dried 
blood. Lot B, besides the mixed grain No. 2, was fed wheat bran, 
corn meal, ground oats and skim milk or milk curd. Both lots 
were fed green alfalfa from the start. Sand and coarse grit were 
freely supplied. The ration containing the animal meal had 
generally somewhat the wider nutritive ratio and for the same 
live weight fed supplied much less protein, although on account of 
‘the much greater consumption of food the amount of protein per 
fowl was considerably larger under this ration. 
The data follow in tabulated form, averaged in periods of one 
week during the time of most rapid growth.
