MILK PRODUCTION 



335 



It is to be noted that these several rations do not 

 differ essentially in quantity but show some variations irx 

 the proportions of the several ingredients in order to 

 reach an adjustment with the protein requirement. The 

 quantities of the several feeds in the Armsby standard 

 are based upon the production values which he has set 

 forth. (See Par. 263.) The Wolff-Lehman ration is based 

 upon the standard for a 1,000-poimd cow giving 27.5 

 pounds of milk, the fat content not stated. 



It should be remarked that these rations would be 

 regarded by practical feeders as sufficiently generous. It 

 is a question whether the amount of protein required by 

 the Wolff-Lehman and Savage standards are not unneces- 

 sarily generous, a point to be considered when protein 

 feeds are more costly than feeds bearing a large propor- 

 tion of carbohydrates.
