The dietary inclusion of aluminosilicates has been reported to enhance pellet quality, improve feed mill throughput, bind toxins, improve feed efficiency, and promote immunological function across a variety of production systems. AZOMITE is a product marketed as a hydrated sodium calcium aluminosilicate containing macro and trace minerals, and rare earth elements and the potential benefits of its dietary inclusion in broiler, layer, and broiler breeder diets was investigated. In a battery study, broilers were fed diets containing 0, 0.125, 0.250, or 0.500% AZOMITE from 0 to 21 d of age. Laying hens were fed a control diet or this diet supplemented with 0.25% AZOMITE from 54 through 98 wk of age, with the hens fed a standard molting diet or this diet supplemented with 0.25% AZOMITE from 71 to 72 wk of age. Broiler breeder hens were fed a control diet or this diet supplemented with 0.25% AZOMITE from the onset of photostimulation at 21 wk of age through 65 wk of age. All 3 dietary inclusion rates of AZOMITE improved (P < 0.05) the feed to body weight gain ratio in broilers fed these diets relative to broilers fed the control diet. In laying hens total marketable eggs, and in broiler breeder hens total settable eggs were increased (P < 0.05) with the dietary inclusion of AZOMITE by 8 eggs per hen. The inclusion of dietary AZOMITE also improved apparent Ca and P digestibility in broilers and tibia ash content in laying hens. The results indicate the dietary inclusion of AZOMITE in poultry diets improves bird performance.
饲粮中添加铝硅酸盐已被报道可提高颗粒质量、提高饲料加工能力、结合毒素、提高饲料效率，并在多种生产系统中促进免疫功能。AZOMITE 是一种以水合的钙钠铝硅酸盐为基础的产品，含有大量和微量矿物质、稀土元素，其在肉鸡、蛋鸡和种鸡日粮中的饲用潜力已被研究。在一项饲养试验中，肉鸡从 0 日龄至 21 日龄饲粮中分别添加 0、0.125、0.250 或 0.500%的 AZOMITE。蛋鸡从 54 周龄至 98 周龄饲粮中添加或不添加 0.25%的 AZOMITE，从 71 周龄至 72 周龄饲粮中添加或不添加标准换羽饲粮加 0.25%的 AZOMITE。种鸡从 21 周龄光照刺激开始至 65 周龄饲粮中添加或不添加 0.25%的 AZOMITE。与对照组相比，饲粮中添加 3 种 AZOMITE 水平均提高了肉鸡的饲料增重比（P < 0.05）。饲粮中添加 AZOMITE 提高了蛋鸡的总合格蛋数（P < 0.05）和种鸡的总可孵化蛋数（P < 0.05），每只鸡分别增加了 8 枚。饲粮中添加 AZOMITE 还提高了肉鸡的表观钙和磷消化率以及蛋鸡的胫骨灰分含量。结果表明，饲粮中添加 AZOMITE 可提高家禽的生产性能。
