The effect of roughages on the retention time of concentrates in the rumen was studied in cattle and sheep fed diets with different concentrate:roughage ratios. The organic matter retention times were calculated from the ratio, OM content in the rumen/mean daily OM intake. In general, the retention time of the maize meal based concentrate diet increased with decreasing roughage inclusion level although the actual retention time was regulated by the nature of the roughage source.
