A complete lack of response was observed to both macro-minerals (Ca, P, Na, Mg, K, S) and micro-minerals (I, Co, Cu, Mn, Fe, Zn) supplementation in the compound feed of Sahiwal male calves. This demonstrates that in cases where animals are kept on adequately balanced compound feed, requirement of the animals seem to be met by minerals coming from feed ingredients and as such supplemental minerals are not required. However, animals kept exclusively on grazing/browsing on range land may -suffer from mineral deficiency.
