Abstract
Two hundred and thirty-nine calves were used to assess the effectiveness of a commercial soluble glass bolus as an intraruminal supplement of copper and selenium. Administration of two boluses per animal raised serum selenium concentration from marginal to adequate but did not prevent the decrease of serum copper concentration from adequate to deficient in some calves over the summer. Key words: Copper, selenium, mineral supplementation, soluble glass, calvesKeywords
