A 76-d feeding trial was conducted with 24 wether lambs (31 kg. initially) to study the interrelationships among dietary P, A1 and Fe. A 2 x 2 x 2 factorial arrangement of treatments included two concentrations of supplement P (O or.25%) with added P as NaH2 PO4, two levels of supplemental Fe (0 or 760 ppm) with Fe added as ferric citrate and two levels of supplemental Al (O or1,450 ppm) with al added as AICI3 6H2 O. The basal diet contained .17% P,40ppm Fe and 168 ppm Al. Phosphorus increased (P<.01) feed consumption but Fe (P<.01) and Al (P<.05) descreased intake. Dietary treatments affected average daily gain (P<.01), with added P improving and Fe or Al depressing gain. Additional P improved gain (P<.05) and intake (P<.01) in the presence of high Al and intake (P<.05) when dietary Fe was high. Serum P was increased (P<.01) by high dietary Fe and reduced (P<.01) by Al. High dietary P increase (P<.05) serum Mg. High dietary Fe increased (P<.01) hemoglobin and hematocrit and increase (P<.01) Fe storage in liver, kidney, spleen and mulscle but decreased (P<.01) kidney Zn concentration. High dietary Al increased (P<.01) liver fe and kidney Zn levels but decreased kidney P an Mg (P<.05) and bone ash and Mg (P<.01). Based on these studies, additional dietary P appeared beneficial in overcoming the adverse effects of high dietary Al or Fe. |
