Show Control Disease; Quarantine Urged Every Precaution Should Be Taken to Halt the Spread of Infection. By Dr. C. D. Grlnnells. Dairy Investigation. Investiga-tion. N. C. Aerlcultural Kxperlment Station WNU Service. Diseased animals should be quarantined quar-antined to prevent the spread of infection. Quarantine not only protects pro-tects the healthy animals, but It also facilitates the treatment of diseased dis-eased animals. Introducing new animals Into a herd without quarantining them for a period of 30 to 40. days is not favored. If at the end of the period they are found to be free from disease, then It is considered safe to place them In the herd. While in quarantine the animals ani-mals should be watched closely for any trace of disease. The period necessary to keep- the animals under un-der close observation varies, depending de-pending upon where the new nni-mals nni-mals came from, the type of animal, ani-mal, and Its physical condition. Animals collected from different farms, assembled in public stock yards, and shipped long distances are dangerous sources of Infection, as they are exposed to many chances for catching disease at a time when their resistance Is lowered. low-ered. But animals which have been hauled only short distances are also liable to become Infected, while many come from herds where disease dis-ease Is present. The need for precaution pre-caution is necessary whenever bringing new stock into a herd. A few Infected animals can spread disease through a whole herd in a few days, and it is risky to wait a day or two before putting put-ting the new stock Into quarantine, even though there is no apparent indication of disease. |
