How do sanitation, vaccines, and confinement help control poultry diseases?

In commercial poultry farming, disease control is achieved through a combination of strict sanitary measures, the use of vaccines, and controlled housing environments.1

• Sanitation: Rigorous sanitary precautions are essential to prevent the spread of pathogens. Because diseases can be transmitted through contaminated equipment, clothing, feed, and feces-contaminated dust or soil, maintaining clean facilities is critical to reducing the risk of infection.1
• Vaccines: The intelligent application of vaccines, alongside the judicious use of antibiotics, allows farmers to manage and prevent the spread of various viral and bacterial diseases that poultry are susceptible to.1
• Confinement: The use of cages for layers and confinement rearing for broilers helps control diseases and parasites by limiting exposure to external contaminants and wild animals. Furthermore, housing birds in cages can reduce cannibalism and lower mortality rates by providing a more controlled environment.12

While these methods are effective for disease management, critics of intensive farming note that such confinement can lead to significant animal welfare concerns, including overcrowding and stress.3
