Inulin is the main component of chicory root extracts . This studypurpose was to assess and compare the effects of chicory extracts and inulin on hen摧s serum and egg lipid .Materials and methods Three‐hundred Nick T hens at ５０ wk of age were divided randomly into five groups . Treatment groupsreceived ０ .１ ％ ( A ) and ２ .０ ％ ( B) chicory root extracts , ０ .１ ％ ( C ) and ２ .０ ％ ( D) inulin in their basal diet , while the controlgroup received only the basal diet . The experiment was carried out during ３０d . At the end of experiment , １８ hens wererandomly selected from each group and ３ ml of blood were withdrawn from the wing‐vein of each hen . Additionally , ３０ eggswere collected from each group . Total cholesterol ( TC ) and triglycerides ( TG ) concentration in serum were measured withenzyme method (Daqing Huang , ２００６ ) . Egg TC and TG concentrations were analyzed by color reaction and gravity method ,respectively ( Shanghai traditional Chinese medicine college , １９７５ ) .Results Group A , B , C reduced ( P ＜ ０ .０５ ) serum TC and TG compared with control , group A showed the lowest serum TCand TG concentrations , with values of TC and TG ３６ .４７ ％ and ４０ .７１ ％ lower ( P ＜ ０ .０１ ) than control , respectively ( Table１ ) . Similar lowering effects of serum lipid by supplementing inulin or chicory extracts into animal diet had been reported( Christine , １９９９ ) , but the lowering degree was different . This could be due to either the difference in experimental animalsused , chicory variety or inulin source .Table 1 The concentration o f TC and TG in hens serum and egg (mean ± SED) .Treatment Serum lipid ( mmol/ l) Yolk lipid ( mg/ g )TC TG TC TGCK ５ .０１ ± ０ .５９Aa ２８ .１０ ± ３ .１０Aa １８ .９１ ± ２ .０３b ３４２ .００ ± ２１ .００aA ３ .２４ ± ０ .３５Bd １６ .５５ ± ２ .３０Bd ２０ .３２ ± ２ .１４a ３４７ .００ ± ３１ .００aB ４ .６０ ± ０ .４２Ab ２６ .００ ± ３ .５０Ab １７ .８５ ± １ .１６c ３１５ .００ ± ５３ .００bC ４ .２２ ± ０ .２９Ac ２４ .２２ ± ２ .９０Ac １９ .４１ ± ２ .１４b ３５７ .００ ± ３７ .００aD ４ .６４ ± ０ .４３Ab ２７ .３５ ± ３ .４０Aa １８ .１４ ± ０ .７８b ３４７ .００ ± ５３ .００aValues in a column with different capital letter are extremely significant different .( P ＜ ０ .０１ ) , with different lowercase are significant different ( P ＜ ０ .０５ ) .Concentrations of yolk TC and TG of group B were ５ .６１ ％ and ７ .８９ ％ lower ( P ＜ ０ .０５ ) than control , respectively . Yolk TCof group A was higher ( P ＜ ０ .０５ ) than control , but there was no difference ( P ＞ ０ .０５ ) in yolk TC and TG between groups Cand D and control ( Table １ ) . Group B had higher activity of decreasing egg lipid than group D , and that could be related toother components such as pectin , chicoric acid in chicory root extracts .Conclusions Chicory root extracts has better decreasing lipid activity than inulin . The optimum supplementing doses fordecreasing serum lipid and egg lipid were different , indicating the need for further research .ReferencesChristine M . , １９９９ .
