Equine parasitology

This Equine parasites for the VT students of 2008 to study from for their finials. It was taken strait from the test that we had in class. I hope that it helps out a little bit just to be able to do the test over and over again and not just reading it.

So how did you do on this section? I hope you did better then you thought that you would do. I know that it is helping me by doing this, since when I took one of the other test I got a good score on it and I will be trying them again later.
