106 Report or tHe DerarrmMent or ANIMAL HUSBANDRY OF THE 
EXPERIMENT WITH CHICKS, SECOND SERIES. 
The lots of chicks, XI, XIII and XV were fed the ration con- 
taining the animal meal and Lots XII, XIV and XVI were fed 
the contrasted ration of vegetable foods supplemented by bone 
ash. ‘Two-thirds of the chicks in Lots XI, XII, XIII and XIV 
were W. Wyandotte-W. Leghorn crosses and the remainder 
Leghorns and Wyandottes. The other two lots contained about 
the same proportion of the cross-bred chicks, the remainder being 
mostly Wyandottes with a few Plymouth Rocks. 
After the chicks in Lots XI and XII were ten weeks old the 
largest cockerels were removed and the remainder fed for two 
weeks longer on the same rations. The other four lots were fed | 
until the chicks were twelve weeks old without separating the 
cockerels. The different lots were fed freely — all the food they 
would readily eat. The nutritive ratios of the rations were 
nearly alike, the ratio for the vegetable-food ration being how- 
ever slightly wider as in the preceding experiments. ‘The con- 
trasted rations in this series were more nearly alike in regard to 
the relations of the protein, ash and fats to the total dry matter. 
The vegetable-food ration contained a slightly less proportion 
of protein and a slightly larger proportion of ash and of fats, but 
these differences were very small. 
The data secured in feeding the six lots of chicks are given in 
the accompanying tables. 
RELATIVE EFFICIENCY AND ECONOMY OF THE RATIONS FOR CHICKS. 
The ration containing the animal meal was eaten somewhat 
more freely. The gains made by the contrasted lots were, how- 
ever, very nearly equal. Lot XI ate nearly 12 per ct. more food 
calculated on the basis of dry matter than did Lot XII, Lot XIII 
ate nearly 16 per ct. more than Lot XIV and Lot XV over 9 
per ct. more than Lot XVI. The gain in weight made by Lot 
XII was less than 4 per ct. greater than that made by Lot XI, 
the gain made by Lot XIII was nearly 10 per ct. greater than
