Three experiments were conducted to evaluate the effects of sodium aluminosilicate (SAS) on performance of chicks and laying hens fed diets varying in nonphytate P (NPP), phytate, and fiber content. In two chick growth experiments a corn and soybean meal diet and a phytate and fiber-free casein-dextrose diet were used. These diets contained .1% NPP and 1.1% Ca and were fortified with 0, .05, or .10% P from KH2PO4 and 0 or .5% SAS. A 3 x 2 factorial arrangement of treatments was used. Sodium aluminosilicate supplementation significantly (P less than .05) depressed growth of chicks fed the corn and soybean meal diets containing 0 or .05% supplemental AP. Sodium aluminosilicate addition decreased (P less than .05) tibia ash and total tibia P (tibia weight x P concentration) in both chick experiments, with the effect being greater for chicks fed the corn and soybean meal diet. In the laying hen experiment, birds were fed corn and soybean meal diets containing NPP levels of .1, .45, or 1.8% and SAS levels of 0 or 1.0%. Egg production and egg yield were depressed (P less than .05) by feeding diets containing .1 or 1.8% NPP, and egg specific gravity was decreased (P less than .05) by feeding 1.8% NPP. Addition of SAS to the .1% NPP diet caused a large reduction (P less than .05) in egg production, egg weight, and feed efficiency, whereas SAS supplementation of the 1.8% NPP diet had no significant effect. Sodium aluminosilicate supplementation increased (P less than .05) egg specific gravity for hens fed the .1 and 1.8% NPP diets.(ABSTRACT TRUNCATED AT 250 WORDS)
进行了三项试验，以评估硅铝酸钠（SAS）对饲喂非植酸磷（NPP）、植酸和纤维含量不同日粮的雏鸡和蛋鸡生产性能的影响。在两项雏鸡生长试验中，使用了玉米 - 豆粕型日粮和无植酸、无纤维的酪蛋白 - 葡萄糖型日粮。这些日粮含0.1%的NPP和1.1%的钙，并分别添加0、0.05%或0.10%的来自磷酸二氢钾的磷以及0或0.5%的SAS。试验采用3×2析因设计。添加硅铝酸钠显著（P＜0.05）抑制了饲喂含0或0.05%补充有效磷的玉米 - 豆粕型日粮雏鸡的生长。在两项雏鸡试验中，添加硅铝酸钠均降低了（P＜0.05）胫骨灰分和胫骨总磷含量（胫骨重量×磷浓度），对饲喂玉米 - 豆粕型日粮的雏鸡影响更大。在蛋鸡试验中，给蛋鸡饲喂含NPP水平为0.1%、0.45%或1.8%以及SAS水平为0或1.0%的玉米 - 豆粕型日粮。饲喂含0.1%或1.8%NPP的日粮会降低（P＜0.05）产蛋量和产蛋率，饲喂含1.8%NPP的日粮会降低（P＜0.05）蛋比重。在含0.1%NPP的日粮中添加SAS会大幅降低（P＜0.05）产蛋量、蛋重和饲料效率，而在含1.8%NPP的日粮中添加SAS则无显著影响。添加硅铝酸钠提高了（P＜0.05）饲喂含0.1%和1.8%NPP日粮蛋鸡的蛋比重。（摘要截短至250字）
