124 BOVINE OBSTETEICS 



(&) Into the vagina of the pregnant cows once weekly a 2 

 per cent, blood-warm creolin solution is to be injected. In the 

 stable the greatest cleanliness must be observed. 



Nocard recommends for the disinfection of the stable floors 

 once a week a 4 per cent, solution of copper sulphate. For the 

 vaginal injections and cleansing of the external genitals and 

 their neighborhood, he suggests the following solution : 



Hydrarg. bichlor. corrosiv 5.0 



Spiritus diluti 50.0 



Glyoerini 50 . 



Aquae destillatse 20 1. 



Nocard advises to practice his prophylactic therapeutics 

 immediately after conception in those stables where abortion 

 reigns. 



It is of special importance not to breed cows until the 

 vaginal discharge has entirely subsided. Otherwise there is 

 danger to infect the bull, who may transmit abortion to other 

 cows. 



Keindl recommends to fumigate the stable with sulphurous 

 acid, to whitewash the walls and stalls and posts, adding | to 1 

 kg. of crude carbolic acid to every 20 1. of whitewash. He 

 orders irrigation of the vagina of infected cows, heifers and 

 calves, twice weekly, with a solution of 1 per cent, acidum 

 carbolicum liquefactum, and 1 to 2 per cent, solution of sodium 

 carbonate ; also treats the prepuce of the bull in the same way. 

 Eeindl insists to have better results with this treatment than 

 with creolin, carbolic acid or sublimate solutions. He thinks 

 it is in consequence of the alkaline solution. 



Brauer, who first experimentally transmitted abortion to 

 pregnant animals, describes his prophylactic therapeutics as 

 follows : Between the fifth and seventh month of the period of 

 gestation, each cow receives hypodermically 10 to 15 g. of a 2 per 

 cent, carbolic acid solution, to be repeated every 14 days. The 

 tail and external genitals are kept clean and washed with a 5 

 per cent, carbolic acid solution several times weekly. Many 

 have tried Brauer's method and report surprising results. 

 Others, on the contrary, have seen bad results from the iujec-
