New York AGRICULTURAL EXPERIMENT STATION. ry 
or ten weeks, two lots of laying hens were fed for six and one- half 
months and two lots for seven and one-half months, and two lots 
of ducklings for ten weeks. Experimental feeding commenced 
with the chicks and ducklings when they were one week old and 
continued until they were ten and twelve weeks old. They were 
all hatched in incubators and reared in brooders. A small out- 
door run on bare ground was allowed each lot. Occasionally a 
chick escaped through the fence into outside flocks where it 
could not be identified and was dropped from the lot. In a few 
lots (Lot VII especially) there was considerable loss at one time 
from sunstroke caused by accidental exposure. Allowance was 
made for any loss caused by accident, obviously uninfluenced by 
feeding. The weight of any that died was accounted in the rec- 
ord as loss in live weight when estimating the food cost per 
pound gain. 
RATIONS. 
One ration for chicks and hens consisted of wheat, cracked 
corn, barley, oats and a mixture (No. 1) composed of 14 parts by 
weight corn meal, 11 parts animal meal, 2 parts each of ground 
oats, wheat bran and pea meal, and one part each of wheat mid- 
dlings, O. P. linseed meal, malt sprouts, brewer’s grains and glu- 
ten meal. The contrasted ration consisted of wheat, barley, oats 
and a grain mixture (No. 2) composed of 7 parts each of pea | 
meal and wheat bran, 6 parts of O. P. linseed meal, 4 parts of 
gluten meal, 3 parts each of corn meal and ground oats and 2 
parts each of malt sprouts, brewer’s grains and wheat middlings. 
One pound of salt was added to every 360 pounds of each mix- 
ture. Each ration for ducklings contained, with one of these 
mixtures, wheat bran, corn meal and ground oats. 
The animal food used in these experiments was the dried and 
ground animal meal. Dried blood, fresh bone, beef scraps and 
pork scraps have often been fed at this Station, but owing to the
