5种牧草补饲对马岗鹅生长性能、肉质及血清抗氧化与免疫的影响
Effects of Five Forage Supplementations on Growth Performance,Meat Quality,Serum Antioxidant and Immune Indices in Magang Geese
摘要
Abstract
To optimize the ecological breeding model of Magang geese,this study selected five common forages in Guangxi—Kudzu vine(Puer-aria montana var.lobata),goosegrass(Eleusine indica),bermudagrass(Cynodon dactylon),hybrid signalgrass(Urochloa hybrid),and napier grass(Pennisetum purpureum Schumach.)—to systemati-cally evaluate their effects as dietary supplements.Ninety healthy Magang geese were randomly divided into 6 groups with 3 replicates of 5 birds each.The control group was fed a basal diet,while the other five groups received corresponding fresh forages supplemented at 2%of initial body weight in addition to the basal diet.The trial included a 10-day pre-experimental period and a 30-day formal experimental period.The results showed that:①growth performance:supplementation with Bermudagrass and Hybrid signalgrass signifi-cantly increased average daily gain(ADG)and reduced the feed-to-gain ratio(F/G)(P<0.05).②meat qual-ity:Hybrid signalgrass decreased shear force in breast and thigh muscles(P>0.05).③immune function:Kudzu vine,Napier grass and Goosegrass significantly increased serum immunoglobulin(IgA,IgG and IgM)levels(P<0.05).④antioxidant indices:all forage-supplemented groups showed significantly increased malo-ndialdehyde(MDA)content and decreased activities of catalase(CAT),superoxide dismutase(SOD)and glu-tathione peroxidase(GSH-Px)(P<0.05),suggesting that forage supplementation may activate immune responses by inducing moderate oxidative stress.In summary,supplementation with hybrid signalgrass and bermudagrass can improve growth performance and meat quality of Magang geese,while Kudzu vine,napier grass and goosegrass help enhance immune function.关键词
