I bought AminoTrace + after a consult with Mad Barn’s nutritionist regarding my 22 YO TB who’s always been a hard keeper. He’s not anymore! No joke, within three days I saw a difference in his energy level and he is now a healthy weight without any change in feed other than daily salt and AminoTrace as recommended. Thsee changes for the better have persisted, even though I have him on a half dose at this time, because he developed a dislike for the pellets. There has not been any change and the white line to seize he suffers from in 1 foot, but making an easy keeper out of him makes it very much worth sticking with it.
