Minerals are inorganic dietary constituents required for various metabolic processes in the body. Availability of minerals to animals in appropriate quantities is a major factor determining the health and productivity. Keeping it in view, a baseline survey was conducted in four districts of Bihar. The aim of the study was to assess the major micro-minerals i.e., copper (Cu), Zinc (Zn), Iron (Fe) and Cobalt (Co) status of soil, plant/fodder and cattle in four districts (Muzaffarpur, Araria, Jehanabad and Bhagalpur) of Bihar. Soil (n=379), fodder (n=372) and plasma samples from cattle (n=290) were collected from four districts of Bihar. Minerals soil, plant/fodder (composite) and plasma were estimated by AAS (Atomic Absorption Spectrophotometry). The average Cu, Zn, Fe and Co contents of soil in four representative districts of three agro-climatic zones of Bihar were found to be 1.212±0.046, 1.283±0.041, 56.036 ±1.273 and 0.403±0.010 µg/gm, respectively. The percent of soil deficient in Cu, Zn, Fe and Co were 23.21%, 38.28%, 3.52% and 27.20%, respectively. Similarly, the average Cu, Zn, Fe and Co contents of fodder were 12.07±0.251, 29.07±0.373, 145.34±8.980 and 0.276±0.012 µg/gm with deficiency of 30.37%, 43.54%, 0.80% and 21.77%, respectively. The overall prevalence of Cu, Zn, Fe and Co deficiency in plasma samples of cattle was 40.90%, 35.55%, 9.03% and 58.20% in the four districts of three agro-climatic zones of Bihar. Significant correlation was observed at 1% and 5% level for Cu, Zn Fe and Co concentrations in soil-fodder-cattle plasma of in almost all districts.
