“…The majority of herbs in this cocktail include Rehmanniae radix preparata, Angelica gigas nakai, Zingiber officinale roscoe, Paeoniae radix, Cnidii rhizoma, and Zizyphus jujube and are rich in polyphenol, flavonoids and polysaccharides, which are reported stimulate the immune system and have antioxidant abilities [ 4 ]. The levels of MPBP in the present study were chosen according to Lee et al [ 5 ] and Lee et al [ 6 ] in situ and in vitro studies. The ingredients and composition of TMR with the MPBP are presented in Table 1 , 2 , respectively.…”

“…They suggested that the by-products were suitable an ingredient of TMR for Hanwoo steers when substituting for TMR by 30 g/kg. In addition, Lee et al [ 6 ] reported that the average DM degradation of MPBP (Panax ginseng, Poria cocos, Glycyrrhiza uralensis, Angrlica gigas, Cnidium officinale, Paeonia lactiflora, Astragalus membranaceus, Zingiberis officinale, Ziziphus jujube var. inermis, and Citrus unshiu) at 12 and 24 h in vitro was higher than that of timothy hay.…”

ObjectiveUsing medicinal plant by-products (MPBP) as feed additives may be an eco-friendly option as substitutes for feedstuffs and may assist in reducing the improper disposal of MPBP. Therefore, this study was conducted to evaluate the influences of MPBP on the meat quality of Hanwoo steers fed a total mixed ration (TMR).MethodsTwenty seven steers (body weight = 573±57 kg) were randomly divided into three treatments with a control group and two tested groups as follows: control, 1,000 g/kg TMR; treatment 1 (MPBP30), 970 g/kg TMR and 30 g/kg MPBP; treatment 2 (MPBP50), 950 g/kg TMR and 50 g/kg MPBP.ResultsAverage daily gain, feed conversion ratio and the Commission Internationale de l’Eclairage L* of muscle were improved (p<0.05, respectively) by MPBP30. Stearic acid (C18:0) was decreased (linear effect, p = 0.012), while oleic acid (C18:1) was increased (linear effect, p = 0.055) by MPBP level. Saturated fatty acid (SFA) and polyunsaturated fatty acid (PUFA) were decreased for MPBP50 while unsaturated fatty acid (USFA) and monounsaturated fatty acid (MUFA) were increased for MPBP 50. USFA and SFA ratio was increased for MPBP50 as well.ConclusionThese results indicated that MPBP supplementation in Hanwoo steers fed a TMR increased feed efficiency and meat color (lightness) with altering fatty acid proportions. Therefore, MPBP may be successfully used in ruminant feeding.
