Examinations of ten samples of fresh cows' milk from the Bureau of 

 Agriculture in Manila are given below. These animals are well selected 

 and are specially cared for by Government officials.

Average fresh cows' milk (Rotch) 











The contents of fresh cows' milk varies between very wide limits in all 

 parts of the world, but in Manila this variation is excessive and is in part 

 due to the alteration in the kind of food to which the cows have been 

 accustomed, to the difference in the care of the animals and to difficulty 

 of securing average milks because of the lack of large herds of cattle. As 

 it is impossible to obtain an average, it is necessary to examine the milk 

 from each animal or herd before it can intelligently be modified for 

 infants' use, and even after these precautions have been taken many of 

 these milks are of a composition which renders proper modification very 

 difficult. The worst cases of rickets to be seen in the Philippine Islands 

 are often observed among children who are fed upon so-called fresh, cows' 

 milk. The average bacterial count in five samples of milk bought in 

 the market was 2,160,000 and the average from five samples from cows 

 from private families gave 765,000. As a result of personal observation 

 regarding the care given to milk, animals, vessels and the surroundings
