The possibility of sulfur-associated PEM can be assessed by measuring the sulfur content of the water and dietary ingredients and then estimating the total sulfur intake on a dry-matter basis. Unfortunately, many of these biochemical features of altered thiamine status are inconsistently observed in cases of PEM, and decreased thiamine status has been observed in diseases other than PEM. The common clinical signs are associated with the GI tract and nervous systems. Sci. Typical cattle ages when permanent incisors erupt, develop, and wear.
