cxxvi Department of Pouf.try Husbandry 



number of students taking courses in the Department was 349, carrying 

 a credit of 1,893 university hours. 



Our anticipated occupation, early in the college year, of the new Poultry 

 Building will relieve the seriously congested condition of office, lecture, 

 and laboratory room that has long existed, and will enable the Department 

 to furnish exceptional facilities for instruction. 



INVESTIGATION 



One hundred and fourteen projects have been investigated since the 

 Department was established. Twelve investigations have been conducted 

 during the past year, as follows : 



1. Breeding to produce a general-purpose fowl that will lay white eggs. 

 Fourth year, one flock, 17 individuals. 



2. To determine the correlation of physical characters and egg-produc- 

 tion. Second year, 558 females. 



3. Methods of feeding fowls to improve the Cornell ration for egg- 

 production. Four flocks, first year, 42 individuals. 



4. Types of rations as affecting egg-production. First year, four flocks, 

 64 individuals. 



5. Winter range versus close confinement as affecting egg-production, 

 fertility and hatching power of eggs, and vigor of stock. Second year, 

 two flocks, 74 individuals. 



6. Breeding for fecundity. Fifth year, three flocks, 233 individuals. 



7. Comparison of large grass range versus small bare yards as affecting 

 egg-production, and fertility and hatching power of eggs. Third year, 

 six flocks, 192 individuals. 



8. Natural versus artificial incubation as affecting vitality, fertility, and 

 hatching power of eggs. Third year, four flocks, 67 individuals. 



9. Breeding to improve the market quality of eggs. First year, nine 

 flocks, 65 individuals. 



10. The effect of removal of the thyroid gland on the health and 

 productiveness of fowls. (In cooperation with the Department of 

 Physiology.) First year, two flocks, 16 individuals. 



11. The feeding of hij^h-fat and high-protein rations and their effect 

 on egg-production, fertility and hatching power of eggs, and vigor of 

 stock. (In cooperation with the Department of Agricultural Chemistry.) 

 First year, two flocks, 30 individuals. 



12. A comparison of nine methods of keeping eggs for hatching. Third 

 year. The number of eggs used for the year 191 1-1912 was 1,650. 



The stock used exclusively in investigations for the year 1911-1912 

 was : Females, 734 ; males, 66 ; total, 800. 



The same number of projects, requiring more fowls, is planned for the 

 next fiscal year.
