Feed mill pellet production rate is of great importance to integrated meat bird production. Ingredients such as dried distillers grains with solubles (DDGS), inorganic phosphate source (IPS), and fat influence production rate and feed quality because of their composition. The naturally abrasive properties of an IPS may scour the pellet die and affect the feed production rate. The objective of the study was to evaluate the effect of a dacitic tuff breccia (Azomite [AZM]) inclusion in a corn, soybean meal, and DDGS–based diet with either dicalcium phosphate (DCP) or tricalcium phosphate (TCP) on pellet mill production rate, hot pellet temperature, and pellet quality. The assessment included 4 experimental treatments in a 2 (DCP or TCP) x 2 (AZM or no AZM) factorial latin square design across 4 manufacturing d with complete blocks in each d. Average temperature and humidity were 16°C and 67%, respectively. There was a 6 percent increase in production rate when AZM was added to DCP diets (0.99 vs. 1.05 MT/h; P < 0.001) and an 8 percent increase in production rate when AZM was added to TCP diets (1.10 vs. 1.19 MT/h; P < 0.001). The increased production rate that favored AZM and TCP diets may be associated with an additive effect of pellet die scouring. Inorganic phosphate source and AZM interacted to affect pellet quality (P < 0.021) demonstrating that increased production rate decreased pellet quality; however, the greatest amount of the observed change (3 percent) would likely have little effect on bird performance. This study was successfully designed to remove confounding treatment effects of the d of manufacture and run order.

一的效果英安凝灰岩角砾(Azomite)在玉米,大豆,和干酒糟与基于可溶物的饮食,在关于制粒机生产速率和颗粒质量的无机磷酸盐源而变化

饲料厂颗粒的生产速度对综合肉禽生产至关重要。诸如可溶干酒糟(DDGS),无机磷酸盐源(IPS)和脂肪之类的成分因其成分而影响生产率和饲料质量。IPS的天然研磨特性可能会冲刷颗粒模具并影响进料生产率。这项研究的目的是评估以磷酸二钙(DCP)或磷酸三钙(TCP)在玉米,豆粕和基于DDGS的日粮中添加达格凝灰岩角砾岩(Azomite [ AZM ])的效果。),制粒机的生产率,热制粒温度和制粒质量。评估包括4个制造d中2个(DCP或TCP)×2(AZM或无AZM)阶乘拉丁方设计的4个实验处理,每个d中有完整的块。平均温度和湿度分别为16°C和67%。有在当AZM加入DCP日粮(0.99对1.05 MT /小时;产率增加了6%,P <0.001),并在当AZM加入到TCP饮食生产速率增加8%(1.10 VS 1.19 MT / h;P <0.001)。有利于AZM和TCP日粮的生产率提高可能与颗粒冲模冲刷的累加效应有关。无机磷酸盐源和AZM相互作用会影响颗粒质量(P<0.021)表明增加的生产率降低了颗粒质量;但是,观察到的最大变化(3%)可能对家禽的生长几乎没有影响。这项研究成功地设计了消除制造和运行订单的混淆处理效果的方法。
