Multidimensional Evaluation of Nutritional Value of Five Common Woody Feed Plants
摘要
Abstract
This resesach constructed a five-dimensional evaluation system of"basic nutrients-pure nutrients-active compo-nents-safety characteristics-processing properties"and combined it with the CRITIC weighting method for quantitative analysis to systematically evaluate the nutritional value of Ginkgo bi-loba leaves,Broussonetia papyrifera leaves,Morus alba leaves,Acer truncatum leaves and Artemisia argyi leaves as leafy feed.The results showed that the crude protein(CP)content of B.papyrifera leaves(27.94%)was significantly higher than that of the other four kinds of forage leaves(P<0.05),while the crude fiber(CF)content(9.29%)was sig-nificantly lower than that of the other four kinds of forage leaves(P<0.05).Moreover,the contents of aflatoxin B1(ABF1,1.77 μg/kg),deoxynivalenol(DON,0.18 μg/g)and zearalenone(ZEN,54.61 μg/kg)were significantly lower than those of the other four kinds of forage leaves(P<0.05).Its scores of conventional nutrients(S1=0.571),feed-ing safety(S3=0.710)and comprehensive score(ST=0.534)ranked first.The contents of total flavonoids(42.15 mg/g),chlorogenic acid(11.72 mg/g)and total phenols(19.31 mg/g)in A.truncatum leaves were significantly higher than those in the other four kinds of forage leaves(P<0.05),with the best score of active components(S2=0.788)and the second comprehensive score(ST=0.478).The contents of ether extract(EE,5.55%)and vitamin E(VE,46.52 mg/kg)in G.biloba leaves were significantly higher than those in the other four kinds of forage leaves(P<0.05),but the contents of AFB1(7.44 μg/kg)and ZEN(385.06 μg/kg)were significantly higher than those in the other four kinds of forage leaves(P<0.05).Its scores of conventional nutrients(S1=0.522)and active components(S2=0.466)ranked second.The oxalic acid content(6.08 mg/g)and angle of repose(35.2°)of M.alba leaves were significantly lower than those of the other four kinds of for-age leaves(P<0.05),while the zinc content(166.75 mg/kg)was significantly higher than that of the other four kinds of forage leaves.Its feeding safety score(S3=0.541)ranked sec-ond and comprehensive score(ST=0.443)ranked third.The contents of proanthocyanidins(8.29 mg/g),copper(20.05 mg/kg),iron(472.42 mg/kg)and manganese(149.60 mg/kg)in A.argyi leaves were significantly higher than those in the other four kinds of forage leaves(P<0.05),with the third score of active components(S2=0.297).In conclusion,B.papyrifera leaves are suitable for development as protein-type feed resources;A.truncatum leaves and G.biloba leaves have obvious advantages in active components and potential for development as functional feed additives;M.alba leaves have good performance in feeding safety and processing properties,while A.argyi leaves have supplementary value in specific nutrients and bioactive components.Through sci-entific and systematic multi-dimensional evaluation,this study provides theoretical and data support for the precise development of leafy feed resources and the implementation of the"wood instead of grain"strategy in low-carbon animal husbandry.关键词
