This study was undertaken to assess the Magnesium content of soil, feed, fodder and serum in Kolhapur district of Maharashtra, during different seasons of the year. Atomic absorption spectrophotometry (AAS) was used to evaluate the mineral contents of samples. Overall mean levels of Mg in soil, feed and fodder samples from all the tehsils were above the critical value whereas in serum sample were at par with the critical value. In all tehsils the overall average values of soil magnesium were significantly highest in rainy season followed by summer and winter season in Panhala tehsil and with no significant difference in Kagal tehsil. In Karveer and Gadhalhings values differ significantly among the seasons with highest in rainy followed by winter and summer. The Percent Deficient Samples (PDS) for Mg in soil, feed and fodder for Kolhapur district were nil and for serum samples were 2.26%. However, the PDS for Mg in serum was observed 5.41 and 4.17% in Karveer and Gadhalhings tehsil respectively. In conclusion, it is necessary to supplement these minerals in ration by formulating area specific mineral mixture in order to sustain normal levels and maximize production of cattle.
