MARKETING MILK 



61 



Example : How many pounds each of 30 per cent, 

 cream and 3.5 per cent, milk are required to make 25 

 per cent, cream? 



21.5 = Ibs. of 30% cream. 



3-5% 



= Ibs. of 3. 5% milk. 



21.5, the difference between 3.5 and 25, is the 

 number of pounds of 30 per cent, cream needed ; 

 and 5, the difference between 30 and 25, is the num- 

 ber of pounds of 3.5 per cent, milk needed. There- 

 fore, any given amount should be mixed in the 

 proportion of 5 parts milk to 21.5 parts cream. 



MARKET MILK 



The essentials. The rapidity with which milk 

 deteriorates and the impossibility of really making it 

 perfect after it has been neglected, especially when 

 it is remembered that much of the milk shipped does 

 not reach the consumer until it is 36 to 48 hours 

 old, make it imperative that milk should have the 

 right care from the start. The essential features 

 for good market milk are that it shall be from 

 healthy cows, fed on feeds free from strong odors 

 and flavors. Dust and manure, especially, with 

 their accompanying load of bacteria, should be kept 

 out of the milk, and it should be immediately cooled
