Here's a breakdown of the reasons:
* Economic Importance: Animals are crucial for food production, transportation, and companionship. Ensuring their health was essential for maintaining economic stability and human well-being.
* Human Health: Zoonotic diseases (diseases that can spread from animals to humans) were a significant threat. Understanding animal health was vital for preventing disease outbreaks and protecting human health.
* Animal Welfare: As societies evolved, there was growing concern for the ethical treatment of animals. Veterinary medicine played a crucial role in improving the living conditions and health of animals.
* Scientific Progress: The scientific revolution spurred advancements in medicine. Applying scientific principles to animal health led to a deeper understanding of diseases, treatments, and prevention.
In summary, the development of veterinary medicine was driven by a complex interplay of economic, public health, ethical, and scientific concerns, all focused on improving the lives of both animals and humans.
