Studies on the levels of certain minerals in soil, fodder and serum of dairy animals

A study was undertaken to find out certain macro and micro mineral levels (Ca, P, Mg, Zn, Fe, Mn and Cu) in soil, fodder and serum of dairy cattle owned by College of Veterinary Science, AAU, Khanapara, Guwahati-22. The soil and fodder samples were collected and processed following the procedure of Mitchell and Rhue (1979) and Fick, et al. (1979), respectively. The serum samples was analysed as per method of Fick et al. (1979) with the help of Atomic Absorption Spectrophotometer. The phosphorus content in soil, fodder and serum was found below the critical level whereas the levels of Ca, Mg, Zn, Fe, Mn and Cu were observed above the critical level. Hence, phosphorylation of soil including supplementation of phosphorus to the livestock may be practised.
