This drastic change in the weather can be problematic for animals. Here are some signs to look for if your pigs are not feeling well. Deep coughing, runny noses, body is hunched, thumping chest or caved in side, tail down, laying off by themselves. Best advice I can give people when you see this is to NOT wait, immediately call a vet and explain what you are seeing. Common treatment for these types of symptoms can vary and pigs (like humans) respond differently to different antibiotics. Diarrhea and loose stool are not uncommon especially when changing protein levels of feed and change in water.
