Lowlands hold important potential for sustainable agriculture in South Sumatra. High acidity of soil and water and practice of domestic waste disposal in the area could be associated with a higher level of micro minerals in forages and grazing animals. This study aimed to evaluate the concentration of copper (Cu), manganese (Mn), zinc (Zn), iron (Fe), lead (Pb), and cadmium (Cd) in the water, forage, and buffalo hair, to compare the concentration of the metals in the forage on residential area and grazing area and to evaluate relationships between age and concentrations of the heavy metals in the buffaloes’ hair. The concentrations of the minerals were Fe > Mn > Zn > Pb > Cu > Cd in the water, Fe > Mn > Zn > Pb > Cu > Cd in the forage and Fe > Mn > Cu > Zn > Pb > Cd in the buffalo hair. Concentrations of Pb in water and forages exceeded the permissible limits for drinking water and feeds of livestock. The levels of the heavy metals in forages on the residential and grazing areas were not different and no significant correlation between ages of the animals and concentrations of the metals in the hair. In the forages, Cu–Mn and Fe–Pb while in the hair Cu, Zn and Pb strongly correlated. The principal component analysis revealed that the levels of metals concentration in the forages and buffalo hair associated with two main factors of natural resources.

低地对于南苏门答腊的可持续农业具有重要的潜力。该地区土壤和水的高酸度以及生活垃圾处理的做法可能与草料和放牧动物中较高水平的微量矿物质有关。本研究旨在评估水、饲料和水牛毛中铜 (Cu)、锰 (Mn)、锌 (Zn)、铁 (Fe)、铅 (Pb) 和镉 (Cd) 的浓度，以比较居住区和放牧区草料中的金属浓度，并评估年龄与水牛毛发中重金属浓度之间的关系。水中矿物质浓度为Fe > Mn > Zn > Pb > Cu > Cd，饲料中Fe > Mn > Zn > Pb > Cu > Cd，水牛Fe > Mn > Cu > Zn > Pb > Cd头发。水和饲料中铅的浓度超过了饮用水和牲畜饲料的允许限值。居住区和放牧区牧草中重金属含量无差异，动物年龄与毛发中重金属浓度无显着相关性。在牧草中，Cu-Mn 和 Fe-Pb，而在毛发中，Cu、Zn 和 Pb 呈强相关。主成分分析表明，牧草和水牛毛中的金属浓度水平与自然资源的两个主要因素有关。居住区和放牧区牧草中重金属含量无差异，动物年龄与毛发中重金属浓度无显着相关性。在牧草中，Cu-Mn 和 Fe-Pb，而在毛发中，Cu、Zn 和 Pb 呈强相关。主成分分析表明，牧草和水牛毛中的金属浓度水平与自然资源的两个主要因素有关。居住区和放牧区牧草中重金属含量无差异，动物年龄与毛发中重金属浓度无显着相关性。在牧草中，Cu-Mn 和 Fe-Pb，而在毛发中，Cu、Zn 和 Pb 呈强相关。主成分分析表明，牧草和水牛毛中的金属浓度水平与自然资源的两个主要因素有关。
