Dicalcium phosphate (DCP) is a commonly used mineral supplement in poultry diets due to its high bioavailability of calcium and phosphorus (NRC, 1994). When included in poultry feed, DCP can interact with other dietary minerals such as zinc, iron, and manganese, potentially affecting their absorption and utilization (Ravindran et al., 2005). For instance, high levels of calcium from DCP may form insoluble complexes with zinc and iron, reducing their bioavailability (Hassan et al., 2010). Similarly, the presence of phytates in feed ingredients can further compound mineral interactions by chelating minerals and impairing their absorption (Kumar et al., 2012). Additives such as phytase enzymes are often used to mitigate these effects by hydrolyzing phytates, thus enhancing mineral availability (Adeola & Cowieson, 2011). The interaction between DCP and other feed additives like organic acids can influence mineral solubility and absorption (Selle et al., 2013). Furthermore, certain feed processing methods, such as pelleting, may affect mineral stability and bioavailability (Gous et al., 2014). It is also important to consider that mineral interactions can influence the immune response and overall health status of poultry (Liu et al., 2017). Therefore, balanced inclusion of DCP alongside other minerals and additives is crucial to optimize mineral nutrition and poultry performance (NRC, 1994). Overall, the interactions between DCP and other dietary components are multifaceted and require careful consideration to prevent nutritional deficiencies or toxicities (Kidd et al., 2011).
