Introduction

Pig Disease Diagnosis Expert System (PDDES) is a mobile application designed to help veterinarians, para-veterinarians, and farmers identify pig diseases based on observed symptoms.

PDDES currently supports diagnosis for 12 major pig diseases, including African Swine Fever (ASF), Classical Swine Fever (CSF), Porcine Reproductive and Respiratory Syndrome (PRRS), Porcine Circovirus (PCV), Swine Pox, Foot and Mouth Disease (FMD), Anthrax, Haemorrhagic Septicaemia (HS), Greasy Pig Disease (Exudative Epidermitis), Erysipelas, Mange Infestation, and Piglet Diarrhoea. With multi-language support and an intuitive interface, the app helps users quickly assess pig health conditions and supports timely disease management decisions.
