Newcastle/Ranikhet Disease Management in Chicken: Symptoms, Treatment, Diagnosis, and Prevention

Newcastle disease is a highly contagious viral infection that affects domestic poultry and a wide range of bird species, causing clinical symptoms, including respiratory, nervous, and gastrointestinal manifestations. The severity of the disease is influenced by the virulence of the virus and host susceptibility.

Newcastle/Ranikhet Disease Management in Chicken

The disease is a major concern for the global poultry industry due to its economic impact and the potential for trade restrictions. Early detection and appropriate control measures are crucial to minimize the spread of Newcastle disease and prevent its devastating effects on the poultry industry.

Newcastle/Ranikhet Disease Management in Chicken

Disease cycle of Newcastle Disease

  • Introduction of the virus into a susceptible bird population, often through contact with infected birds or contaminated equipment or premises.
  • The virus replicates in infected birds’ respiratory and intestinal tracts, causing a range of clinical signs, including respiratory distress, nervous signs, and digestive disturbances.
  • In the infected birds of their, their feces, respiratory secretions, and egg products contaminate the environment and potentially infect other birds.
  • The virus lives in the environment for several weeks or months, depending on factors such as temperature and humidity.
  • Infected birds may recover from ND and develop immunity or die from the disease.

Symptoms of Newcastle Disease

  • Loss of appetite
  • Coughing
  • Gasping
  • Nasal discharge
  • Watery eyes
  • Bright green diarrhea
  • Swollen and discolored (purple or blue) combs and wattles
  • Nervous signs such as paralysis and convulsions
  • Drop in egg production.
  • Soft-shelled or malformed eggs

These symptoms may vary in severity depending on the strain of the virus and the age and species of the bird. In some cases, infected birds may not show any clinical signs of the disease. It’s important to report any suspected cases of ND to the appropriate authorities to help prevent the spread of the virus.

Large Scale Poultry Farming

Impact of Newcastle Disease

Newcastle Disease (ND) significantly impacts the poultry industry and beyond. Here are some of the key impacts:

  • Economic losses: ND is considered one of the most dangerous poultry diseases due to its high mortality rates and negative impact on egg production. Outbreaks can lead to significant economic losses for the poultry industry, particularly in developing countries where small-scale poultry farming is a common source of income.
  • Disease control measures: Controlling and preventing the spread of ND requires costly and time-consuming measures, such as vaccination, quaranti
