Seluenium (Se) and tocopherol (Toc) levels in the blood and foodstuffs were examined in 25 calves and 26 cows in nine barns kept together with calves suffering from white muscle disease.<BR>Marked increase of serum CPK activity was observed in 64% of the calves and 27% of the cows. Deficient levels of serum Toc (under 70μg/100 ml in calves and 150μg/100m<I>l</I> in cows) were recognized in 12% of the calves and 42% of the cows. All the calves and 92% of the cows showed deficient levels of serum Se, less than 35 ppb, and all the calves and cows showed low activity, less than 30 enzyme units in blood GSH-Px.<BR>Close correlation (r=0.81, p<0.01) between serum Se levels and blood GSH-Px activities was recognized in all the cattle.α-Toc concentration of foodstuffs in eight barns was low levels less than 3mg/100g DM, and Se was also deficient levels less than 50 ppb DM. Close correlation (r=0.87, p<0.01) between Se concentration in the main foodstuffs and serum Se levels of the cows was also recognized.<BR>From the results described above, there were many suggestive findings for subclinical muscular disorders which were closely related to deficiencies of Toc and Se in the calves and cows kept together with calves suffering from white muscle disease.
