概括

这项研究估计了韩国猪每年排泄的 (P),发现了基于猪年龄和饮食的显著差异. 这项研究为管理猪养殖造成的P污染提供了关键数据.

科学领域:

动物科学动物科学
环境科学环境科学
农业科学农业科学

背景情况:

猪的 (P) 排泄是一个重要的环境问题,导致水污染.
准确估计P排泄对于开发可持续养猪实践至关重要.
食P和植物酸-P水平因不同猪生长阶段和饮食而有所不同.

研究的目的:

为了估计韩国猪每年排泄的 (P).
分析商业猪食中的P和P酸盐度.
根据食成分和猪生长来开发一个预测P排泄的模型.

主要方法:

从16个农场收集了58个商业猪食样本,用于P和P酸盐-P分析.
利用Gompertz模型估计料摄入量,并对母猪进行了NRC数据的调整.
开发了计算便和尿液P排泄的方程,包括植物酶度.

主要成果:

在饮食中分析的P度在0.54%至0.66%之间.
与生长猪或母猪饮食相比,幼猪饮食中的植物酸含量较低 (p < 0.05).
估计每年P排泄量:市场猪每年1.94公斤,孕母猪每年3.26公斤,哺乳母猪每年6.89公斤.

结论:

韩国所有猪的年度P排泄总量估计为2.15公斤/年.
饮食管理,特别是植物酶补充剂,可以影响P排泄水平.
调查结果为韩国猪产业的环境影响评估和P管理策略提供了必要的数据.

The Phosphorus Cycle

The Phosphorus Cycle

Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.
