摘　　要：本试验旨在研究不同水平辣椒秸秆饲粮对杜湖杂交羔羊生长性能、养分表观消化率和血清指标的影响。试验采用单因素完全随机设计,选取3~4月龄、体重为(29.58±2.06)kg的杜泊羊×湖羊杂交F1代公羔50只,随机分为5组,每组10个重复,每个重复1只羊。各组分别饲喂含有0(对照组)、5%、10%、15%和20%辣椒秸秆(干物质基础)的等能等氮全混合颗粒饲粮。预试期7 d,正试期66 d。结果表明:1)与对照组相比,20%辣椒秸秆组杜湖杂交羔羊第57天体重显著降低(P<0.05);第1~28天,10%辣椒秸秆组干物质采食量(DMI)极显著提高(P<0.01),15%辣椒秸秆组和20%辣椒秸秆组DMI显著或极显著降低(P<0.05或P<0.01);第29~56天,10%辣椒秸秆组DMI极显著提高(P<0.01),20%辣椒秸秆组DMI极显著降低(P<0.01)。2)与对照组相比,10%辣椒秸秆组粗蛋白质和总能表观消化率显著提高(P<0.05)。3)与对照组相比,15%辣椒秸秆组和20%辣椒秸秆组血清葡萄糖含量显著降低(P<0.05);10%辣椒秸秆组和20%辣椒秸秆组血清总蛋白含量显著提高(P<0.05)。4)与对照组相比,5%辣椒秸秆组和10%辣椒秸秆组血清谷胱甘肽过氧化物酶活性显著或极显著提高(P<0.05或P<0.01),15%辣椒秸秆组和20%辣椒秸秆组血清丙二醛含量显著提高(P<0.05)。5)与对照组相比,10%辣椒秸秆组和20%辣椒秸秆组血清干扰素-γ含量显著提高(P<0.05)。综上所述,在本试验条件下,饲喂含有5%~15%辣椒秸秆的饲粮能够提高杜湖杂交羔羊生长性能和养分表观消化率,改善血清指标,且以10%辣椒秸秆效果较优。This experiment was conducted to investigate the effects of different pepper stalk level diets on growth performance,nutrient apparent digestibility and serum indices of Dorper×Hu hybrid lambs.Using a single-factor completely randomized design,fifty F1 male lambs of Duper×Hu sheep with body weight of(29.58±2.06)kg aged 3 to 4 months were randomly divided into 5 groups with 10 replicates per group and 1 sheep per replicate.The sheep in each group were fed total mixed iso-energetic iso-nitrogenic granule diets containing 0(control group),5%,10%,15%and 20%pepper stalk(dry matter basis),respectively.The pre-trial period lasted for 7 days and the experimental period lasted for 66 days.The results showed as follows:1)compared with the control group,the body weight of Duper×Hu hybrid lambs in 20%pepper stalk group on day 57 was significantly decreased(P<0.05);during days 1 to 28,the dry matter intake(DMI)in 10%pepper stalk group was extremely significantly increased(P<0.01),DMI in 15%pepper stalk group and 20%pepper stalk group was significantly or extremely significantly decreased(P<0.05 or P<0.01);during days 29 to 56,DMI in 10%pepper stalk group was extremely significantly increased(P<0.01),and DMI in 20%pepper stalk group was extremely significantly decreased(P<0.01).2)Compared with the control group,the apparent digestibilities of crude protein and gross energy in 10%pepper stalk group was significantly increased(P<0.05).3)Compared with the control group,the serum glucose content in 15%pepper stalk group and 20%pepper stalk group was significantly decreased(P<0.05);the serum total protein content in 10%pepper stalk group and 20%pepper stalk group was significantly increased(P<0.05).4)Compared with the control group,the serum glutathione peroxidase activity in 5%pepper stalk group and 10%pepper stalk group was significantly or extremely significantly increased(P<0.05 or P<0.01),and the serum malondialdehyde content in 15%pepper stalk group and 20%pepper stalk group was significantly increased(P<0.05).5)Compared
