Digestibility of Corn Fodder from So. Corn, Field Corn 

 and Sweet Corn. 



Time of experiment, October and November, 1890. 



Animals used, sheep. 



Total period, 12 days. 



Feces collected, last 5 days. 



A determination of the digestibility of the fodders from these 

 varieties of corn was one of the necessary steps in an attempt* to 

 study their relative yield of digestible material. 



Several hundred pounds of the green fodder corn were selected 

 from each variety at the time the crop was cut and weighed. 

 These small lots were stored in such a manner that they would 

 dry without moulding and where they were safe from the depreda- 

 tions of mice. 



The partially dried fodder of the several kinds was finely 



* The details of this experiment are given on subsequent pages.
