Effect of diets supplemented with Wedelia Chinensis plants on nutrient digestibility and growth performance of Hepu geese
摘要
Abstract
[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.关键词
