Good quality feeder pigs should appear healthy, thrifty, vigorous, and alert. In our two years in the project, we have had three Durocs and one Hampshire. Other members of our project have also had Yorkshires. It is important to maintain the health of your pig. The first 2 or 3 weeks are critical, so you should check your pigs several times each day during this period.
Healthy pigs are active and alert with bright looks in their eyes.
A pig will give you many clues when it isn't feeling well. If you think a pig is sick, take its rectal temperature. If it is 2 degrees or more above normal, call a veterinarian immediately. A common problem with pig is stress. Hauling, vaccinating, introducing it to strange surroundings and strange pigs can scare or stress a pig.
