THIRTY-EIGHTH ANNUAL CONVENTION 117 



isolated and should have one attendant who does not take care 

 of or come in contact with the healthy cows. It is important 

 that one person be assigned to the infected herd and that 

 he use the necessary precautions and that he do not walk into 

 the stables where healthy cows are kept. Before he leaves the 

 infected herd he should thoroughly disinfect himself and leave 

 the infected garments in a suitable place so that they can do no 

 harm. If a cow aborts in the main stable she should be immed- 

 iately removed and the premises should be as carefully disinfected 

 as possible, using strong lye solution with plenty of hot water 

 and a five per cent solution of carbolic acid. The most painstak- 

 ing disinfection should be at once commenced. The animal in 

 the quarantine pen should be treated immediately as follows : 

 If the afterbirth has not come away within five to eight hours 

 it should be taken away by one who knows how to perform this 

 operation. The animal should then be irrigated with a two per 

 cent solution of permanganate of potash, and the limbs, tail, 

 etc., should be washed with soap and water and then with this 

 permanganate of potash solution. One capsule containing oil 

 and kreso is then placed into the vagina. This capsule on dis- 

 solving disinfects the vagina and the vagina should be irrigated 

 every other day with this permanganate of potash solution and 

 a capsule inserted. In addition to this the cow should be fed 

 carbolic acid in the feed. The carbolic acid should be prepared 

 as follows : Crude carbolic acid is liquefied and a small amount 

 of glycerin is added to this to keep it in a liquid form. You start 

 in by mixing with the bran two drams of this solution and then 

 gradually increase the dose until it amounts to about six drams 

 per day. The dose is increased according to the virulence of 

 the disease. Best results have been obtained by giving large 

 doses to cattle where the per cent of loss was very great. We 

 have had the best of success with this treatment. Eighty-one 

 out of 211 herds treated reported good results. 



The bull is probably the carrier of the infection, and there- 

 fore the bull should be thoroughly disinfected before and after 

 each service Use some antiseptic solution, as a tablespoon ful 

 of permanganate of potash to a pailful of water. A rubber tube 

 can be used large enough to slip into the sheath of the bull, a
