    Treatment of Inoculated Animals. Animals which react to the tail inoculation usually do not require treatment. In cases where the reaction shows a ten¬ dency to extend upward to the root of the tail, it is recom¬ mended to cauterise the tissues around the tail with a hot iron a few inches above the unner limits of the swelling Immunity. The vaccine will not protect animals that have already- contracted the disease or those which are in the incubative stage of the disease, and it is not expected that immunity will be conferred in non-infected cattle until after the end of the reaction. This means that cases may continue to occur for some weeks after completion of inoculation. Susceptible animals may continue to contract infection the longer immunisation is delayed and they remain in contact with affected animals. 11 arning.—In dealing with an infected herd it is of fundamental importance that all visibly infected animals be segregated without delay and all in-contacts inoculated at once. The tail should not be unduly pulled at the time of inoculation. Surgical operations should not be carried out—castration, bleeding, etc. Work cattle should not be worked if reacting © severely to inoculation. Every care is taken in the preparation of the culture, but no guarantee is given regarding its safety and efficiency. Inoculation behind the shoulder,” subsequent to the tail inoculation is sometimes carried out, e.g. in case of out¬ breaks and when an owner wishes his cattle “ M.P.” branded, but as a general procedure behind the shoulder ” inoculation is not recommended owing to the risk of severe reactions and some mortality occurring. RERWATEK. I his disease is prevalent throughout the Colony, but on some estates, where the cattle are dipped regularly at short intervals lrom or shortly alter birth, a percentage of the cattle born and reared thereon escape infection, and there is a risk of severe losses occurring il the latter are moved to a redwater- infected area.
