Livestock diseases refer to illnesses that affect animals raised for food, fiber, or other agricultural purposes. These diseases can have significant impacts on animal health, welfare, and productivity, as well as on the economy and food supply. Livestock diseases can be caused by various factors, including bacteria, viruses, parasites, and environmental factors. Research in this area focuses on understanding the causes, spread, and prevention of livestock diseases, as well as developing effective treatments and control measures. This research may involve studying the biology of pathogens, developing vaccines, improving diagnostic techniques, and implementing biosecurity measures to prevent the spread of disease. By addressing these challenges, researchers aim to improve the overall health and well-being of livestock populations and ensure a safe and sustainable food supply.
