| 摘 要： | 由于植物性饲料中大部分磷不能被动物吸收利用,生产上往往添加一定无机磷,容易造成禽畜粪中的磷累积,提高环境磷污染风险.为保证种鸡日粮磷需求前提下降低鸡粪磷排放量,设计0、300、500IU植酸酶用量与0.4%、0.3%、0.2%有效磷含量的不同组合日粮进行种鸡饲养试验,研究了不同日粮对鸡粪磷形态的影响.结果显示,添加植酸酶对鸡粪中总磷、有机磷和无机磷含量影响未达显著水平,但显著降低鸡粪植酸磷含量.鸡粪总磷、植酸磷、有机磷和无机磷含量则随日粮有效磷含量增加而显著提高.其中,以0.2%有效磷日粮处理鸡粪总磷、有机磷和无机磷含量最低,0.2%有效磷+500 IU植酸酶日粮处理鸡粪植酸磷含量最低.因此,在生产上降低有效磷含量的同时添加适量植酸酶可以降低鸡粪磷盈余.

| Abstract: | Since most of P in the animal diet can not be efficiently utilized by animals, high level of P remained in the animal manures is often inevitable, leading to increase the risk potential of P pollution. In order to reduce the residual P in chicken manure while ensuring P demand for normal growth of breeding hen, a experiment was conducted to investigate contents and forms of P in the chicken manure as affected by three levels of phytase(0, 300 and 500 IU)and three levels of available P(0.4%, 0.3%, 0.2%)in th... |
