This pasture should be some distance 

 from the other, or so fenced that it 

 will be impossible for the infected 

 and the non-infected animals to get 

 their heads together. 



"(b) Water. — When possible to 

 provide otherwise, reacting cattle 

 should not be watered at running 

 streams which thereafter flow di- 

 rectly through fields occupied by 

 sound cattle. The water from a 

 drinking trough used by infected 

 animals should not be allowed to flow 

 into stables, fields or yards occupied 

 by sound animals. - 



"(c) Stables. — Reacting cattle 

 should be kept in barns or stables 

 entirely separate from the ones occu- 

 pied by the sound animals. 



"Calves from the reacting cows 

 should be removed from their dams 

 immediately after birth. Milk fed to 

 these calves must be from healthy 

 cows; otherwise, it must be properly 

 pasteurized. These calves should not 

 come in contact in any way with the 

 reacting animals. 



"The non-reacting animals should 

 be tested with tub rculin in 6 months, 

 and when reactors are found at the 

 first six months, or at any subsequent 

 test, the others should be tested not 

 more than six months later. When 

 there are no more reactors at the six 

 months' test, annual tests should 

 thereafter be made. All reacting ani- 

 mals should at once be separated 

 from the new herd, and the stables 

 which they have occupied thoroughly 

 disinfected. 



"The milk of the reacting animals 

 may be pasteurized and used. 



"Any reacting animal which de- 

 velops clinical symptoms of tubercu- 

 losis should be promptly slaughtered. 



"An animal which nas once reacted 

 to tuberculin should under no cir- 

 cumstances be placed in the sound 

 herd. 



"As soon as the sound herd has 

 been well established. Infected ani- 



mals should be slaughtered, under 

 proper inspection. 



"Group 3. — Herds which come 

 within this group should be dealt 

 with either as in Group 2, where the 

 nerd is separated, or as in Group 1, 

 where all the animals are considered 

 as suspicious, and an entirely new 

 herd developed from the offspring. 



"In all cases, animals which show 

 clinical evidences of the disease 

 should be promptly eliminated. They 

 should be destroyed if the disease Is 

 evidently far advanced; if not, they 

 may be slaughtered for food under 

 proper inspection. 



"All milk from tuberculous cows 

 that is used for food purposes should 

 be thoroughly pasteurized. This 

 means that it must be heated sufiB- 

 clently to kill or to render harmless 

 any tubercle bacilli that may be pres- 

 ent in it. For this it is necessary to 

 heat the milk for twenty minutes at 

 150 degrees Fahr., or for five minutes 

 at 180 degrees. 



"It is important that pails and 

 other utensils used in carrying the 

 unpasteurized milk should not be 

 used, unless previously sterilized, for 

 storing the milk after It is pasteur- 

 ized. 



When diseased animals are found, 

 the stables from which they are 

 taken should be thoroughly cleansed 

 and disinfected. To accomplish this, 

 all litter should be removed; floors 

 and ceilings should be carefully 

 swept, and the floors, together with 

 the mangers, thoroughly scrubbed 

 with soap and water. Thorough 

 cleansing before the application of 

 the disinfectant cannot be too strong- 

 ly emphasized. After cleansing, a dis- 

 infectant should be applied. A five 

 per cent (5 per cent.) solution of 

 carbolic acid^ a 1-1000 solution of 

 corrosive sublimate, or a four per 

 cent. (4 per cent.) solution of sul- 

 phuric acid may be used. 



If tuberculous cattle have been 

 kept in a small yard, the litter should 

 be removed, the surface ploughed, 

 and the fencing and other fixtures 

 thoroughly cleansed and disinfected.
