The microbial detoxification of mimosine was detected during in vitro studies with rumen fluid from cattle and sheep in Canada. The toxic amino acid, a component of Leucaena leucocephala (Leguminosae), was degraded rapidly (average rate 2.17 g mL 1 h -1) by rumen inocula from sheep on a concentrate diet but inocula from sheep on cubed hay showed much less activity (0.44 g mL -1 h -1). Mimosine was also metabolized by rumen microorganisms from steers on concentrate rations (2.88 g mL -1 h -1) but rates were lower when inocula originated from cattle fed hay, pasture or silage diets (< 1.87 g mL 1 h -1). Our results show that in Canada, rumen fluid contains microorganisms capable of mimosine degradation and that the rates of detoxification are enhanced by rumen microbiota from sheep and cattle on concentrate diets. |
