Abstract:

选用5头平均体重为27.86kg健康三元(杜×长×大)杂交阉公猪,采用5×5拉丁方设计,以真可消化磷(Truedigestiblephosphorus,TdP)为指标,配制了5种日粮真可消化磷含量不同的生长猪试验日粮,并使其总钙与TdP的比例为2∶1,来研究日粮真可消化磷水平对氮、磷的消化率及其排泄量的影响。结果表明,在日粮真可消化磷含量低于0.26%时,日粮磷的真消化率随着日粮真可消化磷含量的上升而升高,当日粮真可消化磷含量超过0.26%后达到0.39%时,磷的真消化率陡然下降,由52.69%下降到49.56%。由试验结果可以推导出,当日粮真可消化磷含量在0.34%左右时日粮磷的真可消化率达到最高56.6%。但是各试验日粮之间磷的真消化率差异并不显著。当以g.kg-1DMI为单位时,粪磷排泄量随着日粮磷摄入量的增加线性增加,线性方程为:y=0.493x+1.1409,r2=0.9574。x表示日粮磷的摄入量,g.kg-1,DMI(DryMatterIntake);y表示粪磷排泄量,g.kg-1,DMI。日粮5对应的粪磷排泄量极显著高于日粮1(P<0.001)、日粮2(P<0.001)、日粮3(P=0.001)和日粮4(P<0.001),试验日粮1、2、3和4之间没有显著差异。当以g.kg-1fecesDM为单位时,日粮5对应的粪磷排泄量最高(25.82),极显著高于日粮1(P<0.001)、日粮3(P=0.005)和日粮4(P<0.001),显
