CHAPTER IX 



BASING STANDARDS ON QUALITY OF 

 MILK 



Oversupply of Protein. While the old German 

 standards have been used generally and are still the 

 most popular in this country, many investigators 

 now hold that the protein requirements are higher 

 than practical experience indicates as being neces- 

 sary. This is particularly the case with dairy cows. 

 Many of our most successful dairymen have ob- 

 tained as satisfactory results and at less cost by us- 

 ing smaller amounts of protein in the rations as 

 when they literally follow the Wolff feeding 

 standard. 



The fact is, all good dairymen use the balanced 

 ration. Many may not do this intentionally, but 

 the feeds they provide follow more or less the stand- 

 ards and furnish approximately the requisite 

 amounts of the digestible nutrients. The feeding 

 stuffs available admit of this. With corn silage, 

 clover hay, cowpea hay, alfalfa, corn stover, mixed 

 hay, the oil meals and the factory by-products, the 

 food requirements are met within reasonable limits, 

 even though the feeder may be unaware of the fact. 

 It is true, nevertheless, that when these rations 

 are analyzed those netting the most profit often 

 show less protein than what the old standards really 

 call for.
