successful results as those obtained by a skilled veterinarian, and it is 

 therefore advisable Ihat the services of such a veterinarian should always 

 be obtained in those districts where it is possible. In many cases it will 

 be found that the injection of air into the udder will be sufficient to 

 combat the disease without any other treatment, but it is always advisable 

 to study the symptoms of each individual case and administer in a 

 rational manner the indicated medicines. 



VII. Prevention. 



The most recent preventive treatment suggested is in line with the 

 favorable results obtained by the injection of air into the udder. It con- 

 sists in allowing the susceptible cow to retain in the udder for 24 hours 

 after calving all the milk except the small quantity required by the calf, 

 which should be taken if possible from each quarter. The distention 

 of the udder naturally follows as in the air treatment and acts as a 

 preventive against milk fever. In the Island of Jersey and at the Bilt- 

 more Farms, N. C, where this practice is common, the number of milk 

 fever cases has been greatly lessened. General sanitary conditions should 

 also be looked "after, such as the supply of pure air and clean stabling, 

 with plenty of clear cool water and laxative foods, such as grasses and 

 roots. Some observers who believe in the microbic origin of the disease 

 have recommended the cleaning of the manure and dirt from the animal 

 and spraying the hind quarters and genitals with a 4 to 5 per cent solu- 

 tion of carbolic acid, lysol, or creolin, just prior to calving. From our 

 present knowledge of the disease, however, this is probably unnecessary.
