have a 60-65 pound pig with blood in his feces. I noticed it two days ago, does not have it in all the stools just some of them. Stool consistency is normal other than the blood in it. Just finished wormer today after 7 day treatment. Eating fairly well and running around. Any thoughts on what it is and how to treat for it

Take a stool sample to your vet. It will only cost $20 and they can tell you if there are still worms.

Sometimes stools will have a bit of fresh red blood. Unless there is a large volume of liquid it isn't much to be concerned about.

If its fresh red blood it came at the end of the digestive process. Its much more of a concern if blood is entering much earlier in the process.
