VACCINATE REGULARLY In the vaccination of heifer calves against contagious abortion, or brucellosis, many farmers are not using the vaccine as much as they could, states the Department of Agriculture. There appears to be a tendency to use the vaccine on each crop of calves for a few years and then, because little trouble has been experienced during those years, to become apathetic about its use. During the years when the vaccine is not used outbreaks of contagious abortion are liable to occur, with serious results. The vaccine should be used year after year on each crop of calves, so that immunity may be established in all animals in the herd as they reach maturity to protect them during their subsequent breeding lifetime in the herd.
