The feeding trial was conducted to investigate the effect of Azolla spp. inclusion in feed ingredient of broiler chickens. Two hundred of day‐old broiler chicks were raised in Farm 15, Faculty of Agriculture, Universiti Putra Malaysia. The birds were individually wing banded, weighed and allocated into four treatment groups (control: 0% of Azolla spp., T1: 5% of Azolla spp., T2: 10% of Azolla spp. and T3: 15% of Azolla spp.). Each group has five replicates and ten birds per pen. All the birds were fed ad libitum during the feeding trial, which lasted 42 days. During the end of the starter and finisher phase, two birds from each replicate were slaughtered. Ileal digesta sample was collected to determine the nutrient digestibility of the Azolla spp. on broiler chickens. Azolla spp. nutritional content was 5.14% dry matter, 24.82% crude protein, 16.64% crude fibre, 2.00% ether extract, 11.59% ash, 34.95% nitrogen‐free extract, 42.52% neutral detergent fibre, 31.15% acid detergent fibre, 16.86% acid detergent lignin, 11.37% hemicellulose and 14.29% cellulose. The result from this study showed T3 (15% of Azolla spp.) has significantly highest (p < .05) in overall body weight gain. However, in terms of feed intake and feed conversion ratio, there were no significant differences (p > .05) among treatments. For the nutrient digestibility experiment, the findings showed compared with a control group, feeding of 10% or 15% of Azolla spp. led to significant improvement (p < .05) in nutrient digestibility. The studies conclude the inclusion of Azolla spp. up to 15% in broiler chicken feed ration can improved growth of body performance and showed no adverse effect on the growth performance and nutrient digestibility of the birds.

满江红的影响。作为饲料原料对肉鸡生长性能和养分消化率的影响

进行喂养试验以研究满江红的影响。包含在肉鸡饲料成分中。马来西亚博特拉大学农学院 15 号农场饲养了 200 只日龄肉鸡。将这些鸡单独进行翅膀绑扎、称重并分配到四个处理组（对照组：0% 的满江红，T1：5% 的满江红，T2：10% 的满江红和 T3：15% 的满江红）种）。每组有五个重复，每栏有十只鸟。在为期 42 天的饲喂试验期间，所有鸡只随意饲喂。在起始阶段和结束阶段结束时，从每个复制品中屠宰两只鸡。收集回肠食糜样品以确定满江红的营养物质消化率。在肉鸡上。满江红属 营养成分为干物质5.14%、粗蛋白24.82%、粗纤维16.64%、乙醚浸膏2.00%、灰分11.59%、无氮浸膏34.95%、中性洗涤纤维42.52%、酸性洗涤纤维31.15%、酸性洗涤纤维16.86%木质素、11.37% 半纤维素和 14.29% 纤维素。这项研究的结果表明，T3（15% 的 满江红 ）显着最高（p < .05) 整体体重增加。然而，在采食量和饲料转化率方面，处理间没有显着差异（p  >.05）。对于养分消化率实验，研究结果显示，与对照组相比，饲喂 10% 或 15% 的 满江红 属植物。导致养分消化率显着提高 ( p  < .05)。研究得出结论，包括满江红属。肉鸡日粮中添加高达15%的日粮可以提高肉鸡的生长性能，并且对鸡的生长性能和养分消化率没有不良影响。
