Feeding Tables and Standards. 



113 



Grouping the returns by sections, and calculating the dry and 

 digestible matter in the rations reported, the foUowiag table was 

 prepared: 



Rations fed by 128 American dairymen as ascertained by WoU — 



Wisconsin Station. 



In these averages we observe a wide variation in the nutrients 

 fed, the minimum falling much below Wolff's standard, while the 

 maximum materially exceeds it. As a summary report of the 

 rations fed by leading American dairymen, this table is valuable, 

 representing as it does the practice of so many experienced feeders. 

 On the other hand, it is unsatisfactory because ta many cases the 

 feed was not weighed, the figures reported being estimates. 



147. Studies by the Connecticut (Storrs) Station. — Atwater and 

 Phelps, of the Connecticut (Storrs) Station, i studied in person the 

 rations used by a number of dairymen in their state. Their work 

 included weighing and sampling the feed and the milk, both of 

 which were analyzed by the Station. (681) The following table 

 presents the extremes observed in these studies:
