Porcine diseases refer to illnesses that affect pigs, which can impact their health and productivity. Common diseases include Porcine Reproductive and Respiratory Syndrome (PRRS), Swine Influenza, and Porcine Epidemic Diarrhea (PED). These diseases can lead to symptoms such as coughing, fever, and diarrhea, affecting both young and adult pigs. Preventive measures, such as vaccination and biosecurity practices, are essential in managing porcine diseases. Farmers often monitor their herds closely to identify any signs of illness early. Proper nutrition and hygiene also play a crucial role in maintaining the overall health of pigs and preventing disease outbreaks.
