A two dimensional survey was conducted to map the distribution of relevant macrominerals in Junagadh district, by collecting feeds and fodder samples at random, taking conceptual village as a unit. The average calcium content (0.56%) in straws was higher, whereas concentrate ingredients were particularly low in calcium (0.05%). The phosphorus content of crop residues and green fodders was 0.10 and 0.23 per cent, respectively, whereas it was higher in concentrate ingredients (0.45%). The magnesium levels were adequate (average levels > 0.39%). On the deficiency side, sodium content was consistently low in straws (0.09%), green fodders (0.10%) and the concentrate ingredients (0.06%). The area under survey seemed rich in potassium content, because all samples were cxtra-ordinarily rich and were far exceeding the requirement level. Sulphur content was low in straws (0.18%), but adequate in concentrate ingredients (0.23%). Variation for all the mineral elements was recorded amongst villages. It was apparent that the levels of calcium, phosphorus, sodium and sulphur were inadequate to meet the requirement of a buffalo yielding 8 kg milk per day, however, the levels of magnesium and potassium were sufficient in the survey area.
