Show TREAT CALVES TWICE YEARLY i Pon't Wait Until Animals Commence i. to Die of Blackleg Before Administering Ad-ministering Treatment. (By G. H. GLOVER, Colorado Agricultural Agricul-tural College, Fort Collins.) '"Calves should be vaccinated for blackleg twice a year, making it a regular chore, and do not wait until they begin to die before getting ready. The period of ordinary susceptibility ranges from three months to two and one-half years. Most of the vaccine on the market is reliable and the unsatisfactory un-satisfactory results are usually due to carelessness on the part of the farmer In not following directions in using it. The agricultural college distributes the government blackleg vaccine free to farmers of Colorado. Orders for vaccine will not be filled promptly, however, unless the applicant states that he has a vaccinating outfit, which s very necessary to administer vaccine vac-cine in this form. A pellet injector will not do, neither will a hypodermic syringe, without the remainder of the outfit, for placing the vaccine in solution. |
