Pigs have a range of parasites and diseases that can be transmitted to humans. Overall, pigs are pretty dirty. These diseases include trichinosis, Taenia solium, cysticercosis, and brucellosis. Pigs are also known to have a lot of parasitic ascarid worms in their digestive system. The presence of these diseases and parasites is one of the reasons why pork should always be well cooked or cured before eating. Undercooked pork will make a person very, very sick.
One of the most important things about raising pigs is maintaining the health of your pig. The first 2 or 3 weeks of life are critical, so you should check your pigs several times each day during this period. Strong appetites, body temperatures of 102.5° F, sleek hair coats, and tightly curled tails are all signs of a healthy pig. Healthy pigs are active and alert animals.
There will be many signs that your pig's health is not doing good. Some of the signs are poor appetite, guantness, rough hair coat, dull eyes, excessive coughing, diarrhea, inactivity and lameness. If your pig has any of these signs, you should follow up to find out what may be wrong with your pig.
If you think a pig is sick, take its rectal temperature. If it is 2 degrees or more above normal, call a vet right away to investigate further.
A common problem with pig is stress. Hauling, vaccinating, introducing it to strange surroundings and strange pigs can scare or stress a new pig in a farm. When a pig is stressed, it is easier for it to get sick. It may eat less feed and grow slower. It is important to minimize stress, especially when you first introduce your pig to a new environment. Some common diseases associated with stress are pneumonia, mad itch, and swine dysentery. Pigs can also get external parasites, such as lice and mange mites, and internal parasites which live inside the pig's body. If your pig is sick, make sure you take care of it immediately and separate it from the rest of the pigs. There are many medications that can help cure your pig but only if you start early in treating the illness.
