DISEASES OF CATTLE 113 



not been discovered. This disease is very contagious and 

 is transmitted by direct communication but not througli 

 the air. Perhaps the most common way of transmitting 

 the disease is by the hands of the milker. 



Symptoms: A slight raise in the temperature, espe- 

 cially that of the udder and teats. They are red, swol- 

 len and tender and after three or four days small pim- 

 ples or pustules will appear on the teats about the size of 

 a pea. The pimples or pustules become larger and within 

 a few days may attain the size of one-half inch in diame- 

 ter. At the end of the second week the pimples or pus- 

 tules burst and discharge an amber colored fluid leaving 

 raw sores, which cause the animal to suffer intensely 

 when being milked. The supply of milk is also markedly 

 decreased in this condition. 



Prevention: A person should not milk both healthy 

 and diseased cows unless the hands are thoroughly 

 washed in a Carbolated Solution; the clothes that are 

 likely to come in contact with the udder, coat sleeves, 

 etc., changed. 



Treatment : It is advisable to give a physic as it has 

 a very good effect on the blood, such as Aloin, two drams, 

 and Ginger, two drams, which is easily prepared and ad- 

 ministered by placing in capsule and giving with capsule 

 gun. 



Also, the application of Zinc Ointment two or three 

 times a day affords immediate relief and causes the 

 sores to heal rapidly. Good results are also obtained by 

 feeding food that is easily digested, as bran mashes, 

 steamed rolled oats and vegetables.

 with saliva and swallows, then it passes into the rumen
