New YorK AGRICULTURAL EXPERIMENT STATION. 37 
The proportion of the total dry matter of the ration supplied 
by the various added foods was on the average about 26 per ct. 
for Lots IV and V, about 24 per ct. for Lot VI, and about 34 per 
ct. for Lot VII. The large proportion in the case of Lot VII, was 
due to the addition of bone meal with the gluten meals to avoid 
any deficiency of phosphate of lime, such as presumably existed 
in the ration for Lot VI. The proportion of the total dry matter 
represented by all the ash constituents was on the average for 
Lot IV 14 per ct., for Lot V 8.8 per ct., for Lot VI 2.8 per ct., 
and for Lot VII 6.4 per ct. During the first four weeks of feed- 
ing this percentage was slightly lower than the average with 
each lot. The proportion of the total protein derived from the 
added food was about 44 per ct. for Lot IV, over 52 per et. for 
Lot V, about 46 per ct. for Lot VI, and 54 per ct. for Lot VII. 
There would have been less variation in this respect had the 
foods used corresponded more closely with preliminary samples. 
The nutritive ratio varied somewhat at different times with each 
lot from about 1:2.3 to 1:3.5, being most of the time consider- 
ably narrower than is necessary. 
RESULTS. 
The condensed records of feeding and the results averaged 
for periods of two weeks are given in the accompanying tables.
