Use of sodium dichromate to estimate ruminal transit rate of feeds

Use of sodium dichromate to estimate ruminal transit rate of feeds

Zootecnica e Nutrizione Animale 14(5): 431-436

Outflow rate and rumen degradability was estimated for soyabean meal marked with sodium dichromate 80 or 40 g/kg in nylon bags incubated for 2 to 24 h in the rumen of 3 cows, mean liveweight 603 kg, with fistulae. The Cr marker caused changes in the structure of the soyabean meal especially the neutral detergent fibre content and decreased degradability of DM and nitrogen in the rumen.
