Among the livestock with the biggest economic potential are cattle, whether for feeding stock,
cattle seed, or other purposes. Everything derived from cattle is valuable, including the meat,
milk, and hides. The spread of diseases that could worsen the cattle's health is the factor that kills
them. In order to identify the sickness in the cattle without requiring a visit to the veterinarian,
the expert system must be used to analyze and use the disease. One of the right methods in this
expert system is the rule-based approach, which started with symptoms to identify the disease. In
order to facilitate illness identification and provide a concise overview, we developed an online
expert system application on Cattles disease based on this issue.
