Disease control programmes have been developed in parallel with the increase in animal production in order to improve animal health animal welfare and the production of healthy foods diseases in animals are controlled due to concerns of animal welfare to prevent infections in humans and animals and due to food safety and trade interests. Livestock disease management can reduce disease through improved animal husbandry practices these include controlled breeding controlling entry to farm lots and quarantining sick animals and through developing and improving antibiotics vaccines and diagnostic tools evaluation of ethno therapeutic options and vector control techniques. The medical mindset sees disease as the enemy and sees control as a self evident good that needs no elaborate justification but a closer examination suggests that many of the negative impacts of livestock disease can in fact be attributable to policy rather than pathogenicity. Control and prevention of disease in feedlot cattle depends on purchasing healthy animals providing a transportation system that minimizes stress a comfortable feedlot pen environment and an adequate feeding system establishing a good surveillance system and judiciously using vaccines and when necessary antimicrobial agents
