When berseem/lucerne/cowpea are available they can be fed along with the straw or other good quality roughages like oats without any concentrate. However, when straws form the basal ration, concentrate are to be fed.
-
When non-leguminous green fodders, like oat, maize, sorghum, good grazing etc, form the basal roughage there is no need to feed concentrate mixture.
