Healthy food must have an adequate balance of macroelements, such as calcium or phosphorus and, microelements, such as iron, copper. This study aimed to evaluate the influence of three extensive systems, during the dry and rainy seasons, and an intensive (feedlot) system in the Eastern Amazon, on the muscle mineral profile of water buffaloes. In total, 12 male buffaloes, aged between 24 and 36 months, slaughtered in commercial slaughterhouses, were used in each of the systems considered: Marajó island, Santarém, Nova Timboteua, and a feedlot. Approximately 5 g of muscle was collected, stored, and frozen, until freeze-dried. The samples were analyzed for the mineral profile using inductively coupled plasma-optical emission spectrometry (ICP-OES). There were significant differences ( < 0.05) for concentrations of sodium (Na), magnesium (Mg), phosphorus (P), sulfur (S), copper (Cu), zinc (Zn), and iron (Fe). Extensive and intensive systems showed significant differences ( < 0.05) for Na, Ca, S, Cu, and Fe concentrations. The season also influenced ( < 0.05) K, Ca, P, S, Zn, and Fe concentrations. The location and season of the year had a significant interaction ( < 0.05) for K, Mg, P, Zn, and Fe concentrations. The study showed that the different Amazonian production systems and the year season influenced the levels of minerals present in buffalo muscle. The values obtained were, in general, higher in extensive production systems, and Marajó Island stood out with higher mineral values in the dry season. Therefore, the meat from animals reared in these systems is a good mineral source for daily human needs.
健康食品必须在宏观元素（如钙或磷）和微量元素（如铁、铜）之间保持适当平衡。本研究旨在评估亚马逊东部旱季和雨季的三种粗放式养殖系统以及一种集约化（饲养场）养殖系统对水牛肌肉矿物质分布的影响。在每个所考虑的养殖系统（马拉若岛、圣塔伦、新廷博泰乌和一个饲养场）中，总共使用了12头年龄在24至36个月之间、在商业屠宰场宰杀的雄性水牛。采集约5克肌肉，储存并冷冻，直至冻干。使用电感耦合等离子体发射光谱法（ICP - OES）对样品的矿物质分布进行分析。钠（Na）、镁（Mg）、磷（P）、硫（S）、铜（Cu）、锌（Zn）和铁（Fe）的浓度存在显著差异（<0.05）。粗放式和集约化养殖系统在Na、Ca、S、Cu和Fe浓度方面存在显著差异（<0.05）。季节也对钾（K）、钙（Ca）、磷（P）、硫（S）、锌（Zn）和铁（Fe）的浓度产生影响（<0.05）。一年中的地点和季节对钾、镁、磷（P）、锌（Zn）和铁（Fe）的浓度有显著交互作用（<0.05）。研究表明，不同的亚马逊生产系统和年份季节会影响水牛肌肉中的矿物质含量。总体而言，在粗放式生产系统中获得的值较高，马拉若岛在旱季的矿物质值更高。因此，在这些系统中饲养的动物的肉是满足人类日常需求的良好矿物质来源。
