植酸酶在饲粮中超量添加的研究进展

植酸酶作为常规饲料添加剂已经普遍应用于饲粮中,用于分解饲料原料中的植酸,释放磷元素,降低用于提供有效磷的磷酸氢钙或其他原料的使用量。随着研究的深入,发现植酸酶的添加量还远远达不到其应有的功效,超量添加植酸酶可以分解超过90%的植酸,还可以提高蛋白质、脂肪、淀粉及矿物质元素的利用率,提高畜禽的生产性能,降低饲料成本,减少环境污染。

Research Progress in Excess Addition of Phytase in Diets

As a conventional feed additive, phytase is mainly used for the degradation of phytate in diets and releasing of phosphorus to reduce the phosphorus from calcium hydrogen phosphate or other phosphorus sources, and has been widely applied to feed industry.Along with the further researches, it was found that the addition amount of phytase was far less than displaying the best effect.Excess phytase can degrade more than90％ phytate, also improve the utilization of protein, fat, starch and mineral elements as well as growth performance of livestock and poultry, and reduce feed costs and environmental pollution.Chinese Journal of An
