I did discover a few months ago that his selenium intake was very low. I have since added the min a vite supplement, which increased his selenium intake to the appropriate level. I do understand that vitamin E is important for the absorption of selenium, but am reluctant to add more vitamin E to his diet than is already there for fear of his absorbing too much selenium (as I know it has a narrow range). A blood panel is a great idea, but I am not sure if its possible at this moment due to very high vet bills that need to be paid off. I will certainly get them done as soon as possible though and will discuss it with the vet.
I managed to find something at the tack store that is said to increase blood cell production (iron based), and another product that is said to help boost the immune system (herbal). I'll check out the ingredients tonight and see if its something that's safe to add to his diet.
Unfortunately free choice hay is not an option at this time. We are limiting his intake of hard food to help prevent impaction colic due to him not being able to chew hay properly. He may lose a bit of weight, but that can easily be put back on when he recovers. I decided on the alfalfa timothy cubes as he has never been on alfalfa hay before, and did not want to shock his system. As he has been on the cubes for almost two weeks, I think it would be safe to start switching him over to straight alfalfa cubes. As his calcium levels were down, I would assume the alfalfa would help get them up as I've heard alfalfa is higher in calcium than other types of hay?
I really appreciate all the responses. I am trying to give him the best chance of fighting off this infection, without damaging anything from the excessive med use. Posted via Mobile Device
