2013
Dhakad, Rakesh Kumar | Jain, Ravindra Kumar
The calcium (Ca) and phosphorus (P) are the major elements and require regular supplementation in the diet of dairy animals. The supplements available in the market were analyzed for their respective contents to evaluate their quality. Ten samples of each i. e. Lime stone powder (LSP), Calcite powder, Dolomite, Calcium carbonate (CaCO₃), Oyster shell grit (OSG) and Di-calcium phosphate (DCP) collected from different sources (dairy farms, poultry farms, market and feed manufacturers) from all four tehsil of Indore district of Madhya Pradesh were analyzed for moisture, total ash (TA), Ca, P and acid insoluble ash (AIA) contents and were compared with the normal recommended levels (BIS). All the calcium supplements were having low moisture (0.39–0.62%) contents, while normal level (2.77%) was reported in DCP. Calcium supplements were having normal TA content (97.21 - 98.40%), while the CaCO₃ was having exceptionally low amount of it (89.15%) with the DCP (89.23%). The AIA content was reported normal in LSP and CaCO₃ (3.70–4.33%), while it was higher in all other supplements (4.33–8.80). The calcium content in most of the supplements were at higher side (32.14–40.82%), except for the dolomite which was at lower side (33.48%) to the normal levels of BIS, while the values in LSP and CaCO₃ remained in normal range. The DCP was having higher Ca but lower P contents to the standard values. The results indicated the adulteration of the sand or silica like substances in these supplements and hence proper strengthening of the regulations regarding the quality control of the feed supplements is essential to overcome the problem.
