The environmental implications of using MCP in large-scale animal diets regarding phosphorus excretion and pollution.

MCP (monocalcium phosphate) is widely used as a phosphorus supplement in poultry and swine diets to meet their nutritional requirements. Its utilization can influence phosphorus excretion and environmental pollution. When MCP is included in large-scale animal diets, it often results in increased phosphorus excretion due to its high bioavailability (Sapkota et al., 2010). Excess phosphorus from manure can lead to eutrophication of water bodies, causing algal blooms and hypoxic conditions detrimental to aquatic ecosystems (Carpenter et al., 1998). The over-application of phosphorus-rich manure on agricultural land further exacerbates soil and water pollution risks (Sharpley et al., 2003). Using MCP as a phosphorus source may also contribute to phosphorus runoff during heavy rainfall events (Kleinman et al., 2010). Additionally, inefficient absorption of MCP can result in phosphorus accumulation in manure, increasing the environmental footprint of manure management (Liu et al., 2013). To mitigate pollution, strategies such as dietary phytase supplementation can reduce phosphorus excretion by enhancing its digestibility (Adeola & Cowieson, 2011). Furthermore, alternative phosphorus sources or feed formulations aiming at reducing MCP inclusion are being explored to minimize environmental impacts (Northey et al., 2017). Overall, reliance on MCP in large-scale animal production emphasizes the need for integrated nutrient management to prevent phosphorus pollution. Implementing precision feeding practices can optimize phosphorus utilization, thereby reducing environmental risks associated with MCP use (Kerr et al., 2018).
