Vaccination schedules in small ruminant farms
Development and implementation of health management plans is the cornerstone of profitable farms; prevention of microbial diseases by means of vaccination is an integral part of such a plan. In every production type and management system in small ruminants, microbial diseases have a major significance, hence their proper control must be based in good health management practices, including use of effective and safe vaccines. Development of various types of vaccines is evolving very quickly in recent years and the improvement of new type of vaccines offers prospects. The article reviews and discusses vaccination programs and latest advances in development of vaccines against diseases that cause major economic losses in small ruminants. Specifically, vaccination schedules for the following diseases are reviewed: bacterial abortion (abortion associated with Brucella melitensis, Campylobacter spp., Chlamydophila abortus, Coxiella burnetii, Salmonella abortus ovis or Salmonella brandenburg), caseous lymphadenitis, clostridial diseases, colibacillosis, contagious echtyma, epididymitis caused by Brucella ovis, footrot, mammary diseases (contagious agalactia, mastitis), paratuberculosis and respiratory diseases (respiratory disease caused by Mannheimia haemolytica or other Pasteurellaceae). © 2015 Elsevier B.V.
