Copper, zinc, iron and manganese concentration of different fodders and feeds were determined to understand whether it is below or above the critical level. In this study samples of rice straw, grasses, tree leaves and concentrate feeds were analysed for different trace elements contents. Rice straw contained high levels of Fe and Mn (>50 and >40 ppm), while the values of Cu and Zn were lower than the critical values (<8.0 and <30 ppm). Both the road side and fallow land grasses contained an adequate level of Cu, Zn, Fe and Mn. Almost all types of grasses contained higher levels of micro mineral (Cu, Zn, Fe and Mn) except Zn (27 ppm) in Khesari grass. Higher concentration of Cu, Fe and Mn were found in tree leaves compared to critical values. All tree leaves contained relatively lower amount of Zn except saora, jackfruit and banana leaves. Copper contents of almost all the concentrates were higher than the critical level. Zinc concentration was higher in rice bran, mustard oil cake, wheat bran, khesari bran, til oil cake, maize crushed (48.7, 35.1, 65.2, 33.2, 52.6 and 32.1 ppm, respectively) as against the critical value. However, Zinc content was lower in matikalai bran (19.9 ppm), wheat crushed (22.4 ppm) and broken rice (19.7 ppm). Most of the concentrates had higher amount of Fe and Mn compared to the critical level.
