Common Diseases of Farm Animals:

1. Define diseases of farm animals: Diseases of farm animals are illnesses or health conditions that affect animals raised on farms. 🐄
2. Identify the causes of diseases of farm animals: The causes of diseases in farm animals can include bacteria, viruses, parasites, poor nutrition, and environmental factors. 🦠
3. Outline some examples of farm animal diseases:
   • Foot-and-Mouth Disease: A viral disease that affects cloven-hoofed animals like cows and pigs, causing fever and blisters on the mouth and feet. 🐮
   • Mastitis: An inflammatory condition of the udder in dairy cows, often caused by bacteria, resulting in reduced milk production. 🐄
   • Newcastle Disease: A viral infection affecting poultry, causing respiratory and nervous system symptoms, leading to high mortality rates. 🐓
   • Scours: Diarrhea in young calves, often caused by bacterial or viral infections, leading to dehydration and weakness. 🐄
   • Blackleg: A bacterial infection in cattle, causing sudden death due to gas accumulation in muscles. 🐄

By understanding these diseases and their causes, farmers can take preventive measures to protect their animals’ health. 🌱
