The assessment of aluminosilicates' impact on the production of chickens, the physical features of the intestines, and leg bones was done. 500 Ross 308 chickens were used and divided into 5 groups. The control group was I. Groups II, III, IV, and V were fed with halloysite and zeolite (1:3 ratio) at 0,5% (1-35 days; starter, grower 1 and 2) and 1% (36-42 days; finisher) levels. Aluminosilicates were also used for the peat litter: II-500 g of halloysite/m; III-250 g of halloysite/m and 250 g of zeolite/m; IV-500 g of zeolite/m; V-130 g halloysite/m, 370 g zeolite/m. During 42 days, growth and feed indicators were recorded. 10 birds from each group were selected for slaughter. The digestive tract, femur, and tibia bones were sampled, and physical features were analyzed (weight, length, and strength). A lower feed conversion ratio on days 23-35 was found in the groups with the aluminosilicates addition. In group V a lower weight of the gizzard was found than in group I. A liver weight was higher in group V than in group III. A higher strength of the femurs was demonstrated in group IV. The tibia bones were characterized by higher strength than the femurs of broiler chickens. The aluminosilicates to feed and litter had no adverse effect.
评估了铝硅酸盐对鸡生产、肠道物理特性和腿部骨骼的影响。使用了 500 只罗斯 308 鸡，并将其分为 5 组。对照组为 I 组。II、III、IV 和 V 组分别在 0、5%（1-35 天；起始、生长 1 和 2）和 1%（36-42 天；育肥）水平下用埃洛石和沸石（1:3 比例）喂养。还将铝硅酸盐用于泥炭垫料：II-500 克埃洛石/米；III-250 克埃洛石/米和 250 克沸石/米；IV-500 克沸石/米；V-130 克埃洛石/米，370 克沸石/米。在 42 天内记录生长和饲料指标。从每组中选择 10 只鸡进行屠宰。采集消化道、股骨和胫骨样本，并分析其物理特性（重量、长度和强度）。在添加铝硅酸盐的组中，第 23-35 天的饲料转化率较低。与 I 组相比，V 组的肌胃重量较低。V 组的肝脏重量高于 III 组。IV 组的股骨强度较高。胫骨骨骼的强度高于肉鸡的股骨。铝硅酸盐对饲料和垫料没有不良影响。
