[目的]探讨蟛蜞菊作为日粮主要成分对鹅生长性能和养分利用率的影响.[方法]将96羽21日龄体重相近的合浦鹅随机分为4组,每组3个重复,每个重复8羽(4公4母)；分别喂4种不同日粮:日粮1为基础精料+鲜象草；日粮2为基础精料+蟛蜞菊鲜草；日粮3为基础精料+10％蟛蜞菊干草粉+蟛蜞菊鲜草；日粮4为基础精料+22％蟛蜞菊干草粉+蟛蜞菊鲜草.试鹅全舍饲,预饲7d后开始进行42 d的饲养,期间进行消化代谢f跟踪,测定日粮养分的消化代谢率.试验结束后测定试鹅血液生化指标和屠宰性能.[结果]日粮组4的试鹅干物质和能量表观消化率明显低于日粮组1、2和3(P＜0.05)；但日粮组2、3和4的纤维物质(酸性洗涤纤维、中性洗涤纤维和半纤维素)消化率明显高于日粮组1(P＜0.05);4组日粮间的养分消化率无显著差异(P＞0.05)；日粮组2试鹅的日均增重明显高于日粮组1和3( P＜0.05)以及日粮组4(P＜0.01)；但日粮组1和3之间没有显著差异(P＞0.05).4组试鹅之间的血液生化指标和主要屠宰性能也没有显著差异(P＞0.05).[结论]只要利用的形式和比例恰当,蟛蜞菊可作为饲养鹅的良好饲料.

[Objective]The studies were conducted to evaluate the effect of diets supplemented with Wedelia chinensis on nutrients digestion and growth performance of goose.[Method]Ninety-six 21 d Hepu geese with similar body weight were randomly selected in 4 groups and given 4 treatments of diets:concentrate + fresh elephant grass (diet 1 ) ; concentrate + fresh W.chinensis (diet 2); concentrate +10％ W.chinensis powder + fresh W.chinensis (diet 3); concentrate + 22％W.chinensis powder + fresh W.chinensis (diet 4).Each group of geese (24 geese in 1:1 of male:female ratio) was fed indoor in triplicate for 42 d and digestion was monitored after 7 d of adaptation to the diets.The apparent digestibility of dietary nutrients was determined and the blood physiological indices and slaughtering traits were also measured at the end of trial.[Result]The results showed lesser apparent digestibility of dry matter (DM) and energy in geese fed with diet 4 compared to those fed with diet 1,2 and 3 (P＜0.05).The geese fed diet 2,3 and 4 showed better apparent digestibility for fibrous materials,including acid detergent fiber(ADF),neutral detergent fiber(NDF) and hemi-cellulose,compared to geese fed with diet 1 (P＜0.05).No significant differences were observed for digestion of other nutrients among the 4 diets (P＞0.05).The geese fed with diet 2 showed higher daily weight gain than those fed with diet 1,3 (P＜0.05) and diet 4 (P＜0.01),however,geese fed with diet 1 and 3 did not show significant difference amongst them (P＞0.05).Also,no significant difference was observed in blood physiological indices and slaughter traits among 4 groups (P＞0.05).[Conclusion]It may be concluded that W.chinensis can be used as a good feedstuff for geese when it is supplemented with diet in proper form and suitable ratio.
