Abstract A study was undertaken to assess the macro-mineral status of feeds and fodders in Kutch district of Gujarat state, for formulation an appropriate mineral mixture for that area. The average calcium content in straws (0.45%) was higher, whereas concentrate ingredients were particularly low in calcium (0.10%). The phosphorus content of crop residues and green fodders was 0.14 and 0.29 per cent, respectively, which was higher in concentrate ingredients (0.52%). The magnesium levels in samples of feeds and fodders were adequate (average levels >0.40%). Sodium content was low in concentrate ingredients but high in green fodders. Due to high sodium content in water, it was not advisable to supplement sodium in diet. The area under survey seemed to be quite rich in potassium, because all samples were extraordinarily rich and were far exceeding the requirement level. Sulphur content was occasionally deficient in ration of milch animals; however, its supplementation was necessary due to high selenium content in feedstuffs. It was apparent that the levels of calcium, phosphorus and sulphur were inadequate to meet the requirement of animals; however, the levels of magnesium, sodium and potassium were sufficient in the surveyed area.
