摘要: Chromium appears to be an essential trace element since 1959, but its effect on ruminal microbes is not clear yet. This experiment was conducted study the effects of organic chromium supplementation rumen fermentation activity. An in vitro technique held using randomized block design with 13 treatments and 3 replications. There were four kinds Cr used, produced different species fungi as carriers. Fungi used carriers Saccharomyces cerevisiae, Aspergillus oryzae, Rhizophus oryzae "ragi tape". The result indicated that optimum 1 mg Cr/kg dry matter. Supplementation matter increased digestibilities. It also tended increase NH3 total VFA production. Propionate production increased, which decreased methane hexose conversion efficiency several treatments. Each fungus carrier resulted activity, within a normal range. concluded either or tape" could Key words : Cr, microbes,
