• Ante-Mortem Disease Diagnosis in Lairage:
• Clinical Lairage Examination:
• Performed within 24 hours of slaughter while animals are alive to detect systemic and zoonotic clinical infections.
• Rabies is readily diagnosed ante-mortem through acute neurological manifestations: behavioral aggressiveness, aimless wandering, excessive salivation, ataxia, abnormal bellowing, and hindquarter paralysis.
• Conversely, cirrhosis is diagnosed only post-mortem upon visceral liver slicing, and tuberculosis/brucellosis require serological testing or carcass lymph node examination.
• Conclusion: Rabies (Option 4).

Correct option: (4) Rabies
