THE HAECKER FEEDING STANDARD 

 The feeding standard formulated by Prof. T. L. Haecker 

 of the Minnesota Experiment Station 2 has found consider- 

 able favor especially in the Middle West. This standard is 

 based upon a long series of investigations concerning the 

 requirements for maintenance and for the production of 

 milk of varying richness. This standard has recently been 

 modified by Savage in the direction of simplicity in form and 

 some increase in the nutrients. 



This standard makes use of the total digestible nutrients 

 and does not exclude the amide nitrogen as is done by Armsby.
