TUBERCULOSIS. 



In Conducting the tuberculin test, each animal in the herd shuuld he marked by a 

 number lag; or the number may be clipped into the hair on right hip, and the 

 number on the tag should correspond with tlie number on the tuljcrculin test sheet, 

 showing a record of the test of each animal in the herd. Test eacli new animal before 

 it is allowed to mix with the herd. If you make the test at once, you will sa\-e all 

 cows that are not affected ; if yc:>u put the test off, the cows which you could save 

 now will sooner or later become diseased and a loss to you. Learn to make the 

 test yourself so that yon may apply it every six months, or at least once a year. 



Stock owners should urge their neighbors to test their cattle at least once a 

 year so as to keep the community free from tuberculosis. 



How to Apply the Test. 



Before commencing the test, each animal should be tied up in the stable for at 

 least three hours. Do not test a sick animal, or one in heat or otherwise greatly 

 excited, twenty-four hours before or after calving, or one just having aborted or re- 

 tained her afterbirth. Avoid testing in extra hot weather. Make no sudden changes 

 of food at any time of test and do not give cold water jitst before taking tempera- 

 ture. Do the work as gently and quietly as possible to prevent unduly exciting the cattle. 

 I ^S 3 CE I" '^^|Tff This Thermometer is to be inserted in the rectum of the 



\l>-^ animal to be tested, thus : fi®" 



Xs/^ place clasp on tail so the thermometer cannot 

 fall out and break. Leave thermometer in place for 



three to five minutes, remove and read figures, and 



then jot thein down on test sheet (included in each outfit) opposite the 

 number of the animal to be tested, as shown by the tag. These number tags 

 are supplied free of charge with each outfit. Begin at cow No. 1 and test 

 each animal in turn, taking each temperature in the same w-ay, being careful 

 to shake the mercury down below 100 before inserting the thermometer. 

 This is done by holding the thermometer tightly, then giving it a quick jerk. 

 A little vaseline applied to the rectum of each animal at beginning of test makes it 

 easy to insert the thermometer.
