Granular Venereal Disease of Cows 1 105 



iodine ointment. Poschel (B. T. W. 1906, p. 323) advises a 

 mixture of lard and bacillol enclosed in gelatine capsules and in- 

 serted with the fingers twice weekly into the vagina. Blau ( Alla- 

 torvosi lyapok, 1906, No. 2) recommends 3% creoline injections, 

 with which he claims to induce a cure in 8-10 days (?). 



Ostertag (Monatshefte f. Prakt. TierheilkundCj 1901, p. 532) 

 would handle the malady with a 2 to 5% solution of lactic acid 

 or 2 to 5% solution of creolin. He warns against stronger 

 solutions than 2.5%, because they irritate greatly and cause con- 

 tinued straining. He excludes silver nitrate as a disinfectant 

 on account of its cost. He warns veterinarians to use care in 

 prescribing to Jaymen, and to get the measurements precise. 

 Such irrigations of the vagina should occur 2 to 3 times daily. 



Ostertag, ]in harmony with the recommendations of R. Frohner, 

 Martens and Ellinger, recommends the following measures for 

 control and eradication : 



1. The isolation of the sound from the diseased, as far as 

 possible. 



2. Disinfection of the stables, especially of the stanchions, 

 floors, gutters and passage ways. 



3. Cleansing the vulva and neighboring parts from the accumu- 

 lated vulvar discharges. 



4. Withdrawal of affected cows from breeding. 



The same rule should be applied to breeding bulls. If there 

 are evidences of preputial discharges, the bull should not be used 

 for breeding until apparently cured. 



In infected herds, the penis and sheath should be disinfected. 

 Ostertag is of the opinion, also, that the disease should be 

 officially recognized, and dealt with as contagious by the veteri- 

 nary police service. 



Without noteworthy exception, all investigators report the 

 malady very obstinate to handle, requiring vigorous and per- 

 sistent treatment, but finally yielding. 



Our experience in handling has been confined to Herd 2. In 

 this herd, a stable containing 38 cows and heifers was placed 

 under treatment on March 6th, or the following days. 



Two cows were placed upon vaginal injections of 0.5% carbolic acid on 

 March 7. From March 7-15 inclusive, No. i apparently improved. On 

 March 16, she strained severely, and the straining was continued after each 

 irrigation, along with increased irritation and injection of the genital mu-
