FEEDING STANDARDS 



In addition to ascertaining the starch values or equi- 

 valents of foods, Kellner, a famous German agricul-

 amount of digestible protein required per day, as well

 tables may be studied in any modern text-book, as 

 well as in the admirable translation made by Dr. 

 Goodwin, of Kellner 's work.* 



It may be here stated that whilst the writer has 

 found Kellner 's feeding standard very useful in his 

 practical work, he is of the opinion that the amounts 

 of digestible proteins recommended by Kellner seem 

 in several instances to be too low for the requirements 

 of animals in this country. 



For instance, for an 11 cwt. cow giving 2 gallons of 

 milk per day, Kellner recommends a ration containing
