蟛蜞菊组成日粮对合浦鹅养分利用和生产性能的影响

Effect of diets supplemented with Wedelia Chinensis plants on nutrient digestibility and growth performance of Hepu geese

  • 摘要: 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.

     

    Abstract: ObjectiveThe studies were conducted to evaluate the effect of diets supplemented with Wedelia chinensis on nutrients digestion and growth performance of goose.MethodNinety-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.ResultThe 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).ConclusionIt 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.
