gauge at the side where the amount given each animal may be 

 easily read off as the fluid lowers in the can. The container may

 overhead wire extending across the stable back of the cows. 



Stables. — Frequent cleaning and free use of stable disinfec- 

 tants is necessary for mangers, partitions, floors, etc., with 

 plenty of lime in the gutter. Manure should be removed and 

 used so that it cannot carry infection to pregnant cows. Feed 

 for breeding females must not be contaminated by discharges 

 from aborting cows, or by manure from calves born of aborting 

 cows. 



For disinfection of the cow stable, litter should be cleaned 

 out of the mangers and stalls; walls, partition, floors, etc., 

 should be thoroughly scrubbed using plenty of water and then 

 be disinfected by means of corrosive sublimate, 1 to 1000 in 

 water, or copper sulphate, 5 oz. to a gallon of water, or, by 

 corrosive sublimate in fresh whitewash in the proportion of 1 

 lb. corrosive sublimate to 1000 lbs. of water (125 gallons). 



Many bulletins on abortion have been issued by state experi- 

 ment stations and the Federal Bureau, of Animal Industry. 

 These may be easily secured and should be consulted for details 

 of herd management and individual treatment. 



This work should be under the supervision of a competent 

 veterinarian who has given special study to the problems 

 involved.
