THE PRESENT STATUS OF INVESTIGATION OF THE 

 PROBLEMS OF POULTRY CULTURE 1 



PRESENTED BY PHILIP B. HADLEY 

 READ BY WM. F. KIRKPATRICK 



In the previous report of your committee on investigation it was stated 

 that of forty-eight Experiment Stations in the United States and Canada, 

 sending replies to circular letters, slightly more than half, or twenty-five, 

 were engaged in the investigation of poultry problems, leaving twenty-three 

 which were carrying on no poultry work. It has been ascertained at the 

 present time, that twenty-seven institutions out of forty-eight, are carrying 

 on investigational work with poultry, while twenty-one are not. In other 

 words, two institutions have during the past year initiated poultry investi- 

 gations. Two institutions among the twenty-one, not at present carrying 

 on poultry investigation, signify their intention of doing so within the 

 coming year. 



As to the subjects of investigation, the following points are to be noted. 

 As was the case one year ago, more energy is being expended under the head 

 of breeding and feeding than in all the other divisions of poultry investiga- 

 tion combined. However, while one year ago ten Stations were engaged in 

 breeding experiments for egg production, at the present time the number has 

 diminished to seven, and one of these instances is the first initiative. This 

 indicates that four institutions have abandoned either permanently or 

 temporarily this phase of breeding work. 



One year ago breeding for meat production was being carried on at two 

 institutions. This year the number has increased to three. 



A year ago there were six stations feeding for meat production. At the 

 present time only four are engaged in this line of investigation; and whereas 

 one year ago six stations were feeding for egg production, at the present time 

 only five are engaged in this investigation, although two more signify their 

 intention of entering this field. 



Another phase of the work in animal feeding is to be considered under the 

 head of Investigation in Nutrition. This work has in view the utility of 

 particular materials, and seeks the reason for it in the chemical composition 

 of the substances concerned. Three stations are engaged in this line of 

 work. 



When we come to the subject of incubation, we find that there are five 

 stations interested in incubation problems against seven of a year ago.
