TABLE XXII. A COMPARISON OF THE COMPOSITION OF 

 MILK FROM DIFFERENT BREEDS 



The Jersey breed is noted for the production of rich 

 milk, cream, and butter. The Holstein-Friesian breed is 

 highly specialized for the production of a large quantity of 

 milk. This milk serves well for the manufacture of cheese, 

 and where the per cent of fat meets city inspection require- 

 ments, a dairy of this breed will prove especially profitable 

 on account of the large yield of milk. The n ilking strains 

 of the Shorthorn breed are desirable both for the production 

 of the home milk supply in rural districts and as fcecf animals. 



148. Danger from Infected Milk. Before being used 

 for feeding infants, cows' milk must be changed in com- 

 position to make it more nearly conform to the composition 

 of human milk. This is accomplished by diluting it with 

 water to reduce the protein and fat and by adding sugar. 



Great care should be taken with the milk used for chil- 

 dren. It is estimated that 500,000 deaths occur annually 

 in the United States from diseases and derangements due 

 to infected or 'bad milk. Milk is an excellent medium for 

 the growth of harmful bacteria, and every precaution should 

 be taken to assure its purity. Where milk is purchased, 

 there is danger from watering, leading to a lowering of its 

 nutritive value, and from preservatives. Even when pro- 

 duced at home, every care should be exercised to see that 

 the cows are healthy and that no poisonous weeds are fed. 

 Any unusual appearance or odor of milk should be regarded 

 with suspicion. 



An abnormal color in milk is easily noticeable. Blue color
