Chronic Respiratory Disease is prevalent in________

Chronic Respiratory Disease (CRD) is a common problem in poultry, particularly chickens. It is a persistent infection of the respiratory system caused by a combination of bacteria and viruses, including Mycoplasma gallisepticum and infectious bronchitis virus. CRD can cause symptoms such as coughing, sneezing, nasal discharge, and reduced growth in infected birds. The disease is highly contagious and spreads easily between birds, making control and prevention a challenge. Good biosecurity practices, such as proper sanitation, isolation of sick birds, and vaccination, can help reduce the spread and impact of CRD in poultry flocks.
