One hundred hybrid male ducks (Mojosari×Alabio) were used to examine the efficacy of chicory supplementation as nutritional feed manipulation on production performance, and blood lipid profile of hybrid ducks.
The ducks were tagged, weighed, and then allotted randomly to one of the four treatment diets using a completely randomized design. The experimental diets were: i) P0 (100% basal diets+0% chicory as control), ii) P1 (95% basal diets+5% chicory), iii) P2 (90% basal diets+10% chicory) and iv) P3 (85% basal diets+15% chicory). For each treatment group, there were 5 replicates of 5 birds each. All experimental diets were isonitrogenous and isocaloric using locally available ingredients.
Hybrid ducks with fed diets supplemented fresh chicory (5%, 10%, and 15%) showed increased feed intake and body weight gain, as well as feed conversion ratio to be smaller than those ducks fed diets without chicory supplementation (control). The ducks fed 10% chicory supplementation contained significantly (p<0.05) lower ash and higher organic matter contents of meat than those ducks fed other diets. The ducks fed 15% chicory supplementation showed the lowest crude protein and cholesterol content of meat among the treatment diets. Ducks fed chicory supplementation showed lower (p<0.05) blood cholesterol and triglyceride levels than those ducks fed without chicory supplementation, while dietary interventions had no major (p>0.05) influence on low-density lipoprotein and high-density lipoprotein levels in duck blood.
In this study, 10% chicory supplementation showed the best results characterized by an increase in growth performance, carcass quality, small intestinal histomorphology, and lower cholesterol levels of meat.
使用100只杂交雄鸭（莫霍萨里×阿拉比奥）研究添加菊苣作为营养饲料调控对杂交鸭生产性能和血脂谱的影响。
给鸭子戴上标记、称重，然后采用完全随机设计将其随机分配到四种试验日粮之一。试验日粮分别为：i）P0（100%基础日粮+0%菊苣，作为对照），ii）P1（95%基础日粮+5%菊苣），iii）P2（90%基础日粮+10%菊苣）和iv）P3（85%基础日粮+15%菊苣）。每个处理组有5个重复，每个重复5只鸭。所有试验日粮均使用当地可得的原料，蛋白质含量和热量相同。
饲喂添加新鲜菊苣（5%、10%和15%）日粮的杂交鸭采食量和体重增加，饲料转化率低于未添加菊苣日粮（对照）的鸭子。饲喂10%菊苣的鸭子肉中灰分含量显著低于（p<0.05）其他日粮组鸭子，有机物含量则较高。在各处理日粮中，饲喂15%菊苣的鸭子肉中粗蛋白和胆固醇含量最低。饲喂添加菊苣日粮的鸭子血液中胆固醇和甘油三酯水平低于（p<0.05）未添加菊苣日粮的鸭子，而日粮干预对鸭血液中低密度脂蛋白和高密度脂蛋白水平无显著影响（p>0.05）。
在本研究中，添加10%菊苣表现出最佳效果，其特征为生长性能提高、胴体品质改善、小肠组织形态学变化以及肉中胆固醇水平降低。
