摘要
主要论述有关磷生物学效价的研究及对磷生物学效价的影响因素,包括对研究方法所采取的标准物、测定指标以及植酸、钙磷水平与VD的添加等因素对磷效价的影响和一些近期发展起来的提高磷生物学效价减少饲料中无机磷添加量的途径与方法,以便降低畜禽粪便中磷的排放与饲料成本,降低畜禽业对环境的污染,发展绿色、环保型畜牧业。
This paper was about the bioavailability and its influential factors, which included the criterion of this research and phytic acids, ratio of calcium and Phosphorus and VD effect on the bioavailability of phosphorus in diets,and some new methods of improving bioavailability of phosphorus, reducing the addition of inorganic phosphorus in order to reduce content of phosphorus in the feces and, cost of diets and environmental pollution.
