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.
进行了饲养试验，以研究在肉鸡饲料成分中添加满江红属植物的效果。200只一日龄肉鸡雏鸡在马来西亚博特拉大学农业学院的15号农场饲养。给这些鸡戴上个体翅号，称重并分配到四个处理组（对照组：0%满江红属植物，T1：5%满江红属植物，T2：10%满江红属植物，T3：15%满江红属植物）。每组有五个重复，每栏有十只鸡。在持续42天的饲养试验期间，所有鸡只自由采食。在育雏期和育肥期结束时，从每个重复中挑选两只鸡进行屠宰。采集回肠消化物样本，以测定满江红属植物对肉鸡的养分消化率。满江红属植物的营养成分含量为：干物质5.14%、粗蛋白24.82%、粗纤维16.64%、乙醚提取物2.00%、灰分11.59%、无氮提取物34.95%、中性洗涤纤维42.52%、酸性洗涤纤维31.15%、酸性洗涤木质素16.86%、半纤维素11.37%和纤维素14.29%。本研究结果表明，T3组（15%满江红属植物）的总体体重增加显著最高（p <.05）。然而，在采食量和饲料转化率方面，各处理组之间没有显著差异（p >.05）。对于养分消化率试验，研究结果表明，与对照组相比，饲喂10%或15%满江红属植物可显著提高（p <.05）养分消化率。研究得出结论，在肉鸡日粮中添加高达15%的满江红属植物可以改善鸡只的生长性能，且对鸡只的生长性能和养分消化率没有不良影响。
