Connective tissue components of samples from skin of minks submitted to 4 different feedings, i.e. (1) control diet, (2, 3 and 4) control diet added respectively filleting scrap as silage; rape-seed meal and Vantocil, a biguanidine product, were analyzed. Skin of animals receiving rape-seed oil (glycosinolates) showed increased content of water, GAG, Hyp, Hyl and decreased fat and Pro, those receiving Vantocil did not show increase of Hyl and GAG in relation to the control-fed group. Increased fur quality was exhibited by the Vantocil-fed group only. Different content of water was found in skins ready to be sold. Differences in GAG type content, specially hyaluronic acid, known to present high water binding capacity, is suggested. Some of the effects observed are discussed as the result of thyroidal deficiency induced by glycosinolate metabolism.
