HYDERABAD, 21 February 2024: Poultry farming is a vital component of India's agricultural sector, providing nutrition and livelihoods to millions. However, the industry faces persistent challenges from various diseases that can decimate flocks and disrupt production.

In this article, we explore the top 10 diseases found in poultry in India, examining their causes, symptoms, treatment options, and the states grappling with these challenges.

1. Newcastle Disease (ND)

   • Causes and Spread: ND is caused by a virus from the Paramyxoviridae family.
   • Symptoms and Impact: Respiratory distress, diarrhea, and high mortality rates.
   • Treatment and Prevention: Vaccination and strict biosecurity measures.
   • States Battling ND: Uttar Pradesh, Telangana, and Andhra Pradesh report frequent ND outbreaks.

2. Avian Influenza (AI)

   • AI Subtypes: H5N1 and H7N9 are common strains affecting poultry.
   • Clinical Signs: Sudden death, respiratory distress, and reduced egg production.
   • Control Measures: Surveillance, culling infected birds, and restricting movement.
   • Affected States: Kerala, Maharashtra, and Gujarat have witnessed recent AI outbreaks.

3. Infectious Bronchitis (IB)

   • Etiology: IBV, a coronavirus, causes respiratory distress and decreased egg production.
   • Treatment Approaches: Supportive care, vaccination, and environmental management.
   • Challenges in States: Karnataka, Tamil Nadu, and Punjab report recurrent IB cases.

4. Marek's Disease

   • Herpesvirus: MDV leads to tumors, paralysis, and immunosuppression.
   • Control Strategies: Vaccination, hygiene, and genetic selection for resistance.
   • State-Specific Concerns: Haryana, Madhya Pradesh, and Rajasthan face Marek's Disease challenges.

5. Coccidiosis

   • Protozoan Parasites: Eimeria species cause enteric infections and reduced growth.
   • Management Tactics: Anticoccidial drugs, vaccination, and improved hygiene practices.
   • Affected Regions: West Bengal, Bihar, and Odisha deal with recurrent coccidiosis cases.

6. Fowl Typhoid

   • Salmonella Gallinarum Infection: Results in septicemia and high mortality rates.
   • Control Measures: Sanitation, vaccination, and strict biosecurity protocols.
   • States Affected: Assam, Jharkhand, and Chhattisgarh report fowl typhoid outbreaks.

7. Infectious Bursal Disease (IBD)

   • IBDV Impact: Immunosuppression, increased susceptibility to secondary infections.
   • Vaccination Programs: Essential for controlling IBD outbreaks.
   • Regional Challenges: Uttar Pradesh, Bihar, and West Bengal battle recurrent IBD cases.

8. Gumboro Disease

   • Avibirnavirus Infection: Leads to immunosuppression and increased mortality.
   • Preventive Measures: Vaccination, biosecurity, and strict hygiene practices.

9. Fowl Cholera

   • Pasteurella multocida Pathogen: Results in acute septicemia and chronic infections.
   • Control Strategies: Antibiotics, vaccination, and vector control.
   • State-Specific Issues: Maharashtra, Goa, and Meghalaya confront fowl cholera challenges.

10. Egg Drop Syndrome (EDS)

    • Adenovirus Infection: Leads to decreased egg production and poor shell quality.
    • Mitigation Measures: Vaccination and improved flock management practices.
    • Focus States: Gujarat, Manipur, and Tripura address EDS-related concerns.

Poultry diseases remain a significant threat to India's poultry industry, impacting food security and livelihoods. Effective disease management requires a multi-faceted approach, including vaccination, biosecurity, and targeted treatment strategies.

States across India are engaged in battling these diseases, implementing surveillance programs and educational initiatives to mitigate risks. Continued research, collaboration, and investment are essential to safeguarding the health and sustainability of India's poultry sector in the face of evolving disease challenges.
