The objective of this study was to investigate the effect of copper (Cu) supplementation, different in dose and source, on Cu metabolism, rumen microbiota, and rumen fermentation characteristics in cattle. Six cannulated cows were used in a Latin square design, receiving following Cu treatments: 10, 35, and 50 mg/kg dry matter (DM) from either Cu sulphate or tribasic Cu chloride, respectively. Cu sulphate appeared to be more bioavailable than tribasic Cu chloride at supplementation of 50 mg/kg DM. Rumen microbiota was not essentially impaired by Cu supplementation. Dry matter degradability was stimulated by rising doses of Cu sulphate between 3 and 12 hours after feeding.
