Therefore, serhes for lternte produts n id in growth promotion, improved feed utiliztion nd mintenne of gut helth re tking ple. Hers speies nd vrious plnt extrts hve reeived inresing ttention s possile AGP replements (Hertrmpt, 2001; Revington, 2002; Huygheert, 2003). The world Helth Orgniztion estimted tht, 80% of the erth s inhitnts rely on trditionl mediine for their primry helth re needs nd most of this therpy involves the use of plnt extrts or their tive omponents (Cifti et l., 2005). Those plnts nd their omponents re pereived s nturl nd sfe y onsumers. Suh omponents re lredy estlished s flvorings in humn nd niml feeds. Aromti plnts hve een used trditionlly in the therpy of some diseses for long time in the world. In different hers, wide vriety of tive phytohemils, inluding the flvonoids, terpeniods, lignns, sulfides, polyphenolis, roteniods, oumrins, sponins, plnt sterols nd phthlides hve een identified (Crig, 1999). Reserh interest hs foused on vrious hers tht posses hypolipidemi, ntipltelet, ntitumor, or immune stimulting properties tht my e useful djunts in helping redue the risk of rdiovsulr disese nd ner.
