4.4 pounds for Lot IX and 6.8 pounds for Lot X. During four 
weeks after the cockerels were removed Lot X consumed about 
5 per ct. more food than Lot IX but the latter made 24 per ct. 
greater gain in weight. The dry matter in the food for each 
pound gain in weight was 5.1 pounds for Lot IX and 6.5 pounds 
for Lot X. During the following four weeks about 14 per ct. 
more food was eaten by Lot IX and only about 4 per ct. greater 
gain made. The dry matter in the food for each pound gain 
was about 5.6 pounds for Lot IX and 5.2 pounds for Lot X. 
RELATIVE ECONOMY OF THE RATIONS FOR CHICKS. 
The cost of food per pound gain in weight for Lot I was 4.1 
cents and for Lot II 4.4 cents. For Lot III it was 5.1 cents and 
for Lot IV 4.5 cents. For the ten weeks with the pullets of the 
combined lots the cost was 7.7 cents for Lots I and III and 8.3 
cents for Lots II and IV. 
The food cost of the growth made during the first eleven 
weeks by Lot V was 4.9 cents and of that made by Lot VI was 
5.0 cents. The cost of that made during this time by Lot VII 
was 5.1 cents and of that made by Lot VIII 5.4 cents. When 
the pullets from the combined lots were fed for four weeks longer 
the cost of the gain made by the birds from Lots V and VII was 
3.9 cents and of that made by Lots VI and VIII 4.3 cents. After 
adding to these lots some more matured pullets from the earlier 
lots, the one combined lot of older birds, from I, III, V and VII, 
made for a month a slow and costly gain while the others, from 
II, IV, VI and VIII, whose growth had been slower, still made 
good gains at moderate cost. The food cost of the gain made by 
Lot IX was 5.5 cents and of that made by Lot X 8.0 cents per 
pound. 
Owing to the large proportion of Leghorns among the chicks, 
heavy average weights were never reached, but average weights 
of one, two and three pounds were always attained much sooner 
by the chicks having the animal food ration. The first four lots 
reached the average weight of one-half pound at about the same
