I. THE ECONOMY OF USING ANIMAL FOOD 

 IN POULTRY FEEDING.* 



W. P. Wheelek. 



SUMMAEY. 



A ration in which about two-fifths of the protein was supplied 

 by animal food was much more profitably fed to chicks than an- 

 other ration supplying an equal amount of protein mostly from 

 vegetable sources but supplemented by skim-milk curd. 



When the two rations were fed to cockerels also, the results 

 were favorable to the animal food, but the difference was not so 

 pronounced as with the chicks. 



Pullets fed the ration containing the large proportion of animal 

 food attained ultimately somewhat the larger average size, but 

 the chief advantage over those fed the vegetable ration was in the 

 more rapid growth and earlier maturity. 



With ducklings much the better results accompanied the feed- 

 ing of a ration in which about half the protein was supplied by 

 animal food. The growth was over three times as rapid as under 

 another ration in which most of the protein was of vegetable 

 origin with enough of skim-milk curd added to supply about one- 

 fourth of the total protein. 



In the general vigor and health of the birds there was some dif- 

 ference in favor of the animal food ration. This difference was 

 very pronounced with the ducklings.
