352 MILK AND THE PUBLIC HEALTH CHAP. 



tests must be arranged through the Milk Commission, or with the 

 approval of the Milk Commission, and must be so planned that the 

 representative of the Milk Commission may be present throughout, 

 and be accommodated at or near the farm in the same way as the 

 doctor who makes the test, if the Commission so desires. 



No test will be regarded as satisfactory to the Milk Commission 

 unless the temperatures are taken through the eighteenth hour 

 after injection. Should the State Department, in state test, feel 

 unable 'to instruct its veterinarian to take temperatures through the 

 eighteenth hour, and should he not do so of his own accord, the 

 Commission may require a private test later at the expense of the 

 owner. 



The farmer for whom the test is made must make sure that a 

 chart of each test is furnished to the Milk Commission, to keep on 

 file, within a week after the test, whether it be a private or state 

 test. The Milk Commission reserves the right to decide what 

 cows shall be kept in the herd. 



Any animal suspected of being in bad health must be promptly 

 removed from the herd and her milk rejected. No cow whose 

 udder is imperfect shall be allowed in the certified herd, nor shall 

 the milk from an udder in any way diseased be put in the certified 

 milk, as long as any disease exists. Do not allow the cows to be 

 excited by hard driving, abuse, loud talking, or any unnecessary 

 disturbance. 



Feed. Do not allow any strongly flavoured food, like garlic, to 

 be eaten by the cows. 



When ensilage is fed, it must be given in only one feeding 

 daily, and that after the morning milking, and the full ration shall 

 consist of not more than twenty pounds daily for the average 

 sized cow. When fed in the fall small amounts must be given 

 and the increase to the full ration must be gradual. 



Corn-stalks must not be fed until after the corn has blossomed, 

 and the first feedings must be in small amounts and the increase 

 must be gradual. If fed otherwise, ensilage and corn-stalks are 

 liable to cause the milk to affect children seriously. 



Cleaning. Groom the entire body of the cow daily. Before 

 each milking, wash the udder with a cloth used only for the udders 

 and wipe it with a clean dry towel. Never leave the udder wet, 

 and be sure that the water and towel used are clean. The tail 

 should be kept clean by frequent washing. If the hair on the 

 flanks, tail, and udder is clipped close, and the brush on the tail is 

 cut short, it will be much easier to keep the cow clean. 



The cows must be kept standing after the cleaning until the 

 milking is finished. This may be done by a chain or rope under 

 the neck. 



5. The Milkers. The milker must be personally clean. He
