How do amino acids impact horse hoof growth and quality?
The amino acid concentration within the horn of good-quality hooves has been shown to be different from that of poor-quality horse hooves. However, a study from Geyer and Schulze in 1994 failed to show an effect of specific amino acid supplementation on the growth of hooves. While the essential amino acid methionine is thought to be important for hoof quality, if fed in excess, it is thought to cause a depletion of iron, copper and zinc, which may be associated with crumbling horn and white line disease.
