Requirements of Certain Minerals for Large Ruminants in Ivtehsana District of Gujarat

An attempt was made to recommend specific quantities of each deficient mineral based on chemical composition and differences in calculated requirements of ruminants in Mehsana district of Gujarat, A buffalo yielding 10 kg milk per day with 7% fat was considered as a standard for such calculations. Calcium requirement is recommended @ 26.6% and P@ 8% in the mineral mixture. Magnesium through feeds was adequate therefore it required no extra supplementation. Extra Zn and Cu content required in mineral mixture was 107 and 5 ppm, respectively. Iron, Mn and Co did not require any further supplementation because feeds and fodders seemed to he adequate in this district.
