A GUIDE FOR KEEPERS OF POULTRY 145 
dry-mash advocates compromise by feeding the ground 
feed in such a way that it is always before the fowls. 
The more logical method is to feed the mash in the morn- 
ing, when wet mash is fed, and the grain in the after- 
noon. \Whole grain naturally digests more slowly than 
that which is ground, and feeding it in the afternoon or 
evening gives the fowls full crops of this slowly digesting 
whole grain to dispose of during the night. Stewart and 
Atwood of the West Virginia Experiment Station con- 
cluded from a careful experiment that it made very little 
difference whether the mash was fed in the morning or 
afternoon. The New York Experiment Station carried 
on an experiment for nearly a year to test the compara- 
tive value of whole and ground grain in feeding for eggs. 
Common hens having a whole grain ration laid much bet- 
ter than did those having ground grain. Leghorn hens 
consumed 20 per cent more feed when fed whole grain for 
the same egg production than did similar hens having 
half their grain ground and moistened. The Hatch Ex- 
periment Station experimented with a lot of Plymouth 
Rock hens, feeding one lot mash in the morning and the 
other mash in the evening. During the winter the hens 
having morning mash laid 793 eggs and those having 
evening mash laid 758 eggs. During the summer the 
hens having morning mash laid 583 eggs, while those 
having evening mash laid 570 eggs. In this case, as in 
others, the time the mash was fed did not seem to make 
any particular difference in egg production. 
In the discussion of feed formulas we shall begin with 
those for chicks just emerged from the shell, and carry 
them forward until they arrive at mature age. From this 
we shall give formulas for feeds for fowls being finished 
for market and for promoting egg production. The
