Description
The physical properties and chemical composition of the sole horn were examined in 120 claws of 30 Holstein-Friesian cows in Hokkaido, Japan. Colour, water saturation, hardness, moisture content, mineral amino acids composition were determined in normal, eroded and ulcerated soles. Normal soles had yellowish brown to reddish discoloration while ulcerated and eroded soles had yellowish brown to black discoloration. Ulcerated and eroded soles had thicker horns than the normal soles. There were no differences in the hardness and moisture content of normal and diseased soles but diseased soles had higher water saturation than normal soles. Total protein fraction of ulcerated and eroded soles was lower than that of normal soles. Serine, glutamic acid and glycine contents of ulcerated soles and serine concentration of eroded soles were lower than those in normal soles. Ash and mineral components were higher in diseased soles than in normal soles
