摘　　要：试验旨在研究不同纤维源饲粮对家兔生长性能、屠宰性能、免疫器官发育及抗氧化能力的影响。试验选取96只体重相近、健康的35日龄伊拉肉兔,随机分为4组,每组8个重复,每个重复3只。4个试验组分别使用大豆皮、稻草、花生秧和苜蓿为唯一纤维源配制全价饲粮。预试期7 d,正式试验期30 d。结果显示,大豆皮组、花生秧组和苜蓿组的末重和平均日增重均显著高于稻草组(P<0.05),稻草组、花生秧组和苜蓿组的平均日采食量显著高于大豆皮组(P<0.05)。大豆皮组、花生秧组和苜蓿组的宰前活重显著高于稻草组(P<0.05),花生秧组和苜蓿组的胴体重、半净膛重和全净膛重均显著高于稻草组(P<0.05)。苜蓿组的肝脏指数显著高于其他组(P<0.05),圆小囊指数显著高于大豆皮组和花生秧组(P<0.05)。大豆皮组的血清谷胱甘肽过氧化物酶(GSH-Px)活性显著高于其他组(P<0.05)。研究表明,苜蓿作为家兔饲粮的纤维源综合表现较好,花生秧仅次于苜蓿,优于大豆皮和稻草。The purpose of the study was to study the effects of different fiber sources feeds on the growth performance,slaughter performance,immune organ development,and antioxidant capacity of rabbits.In the study,96 healthy 35-dayold Ira meat rabbits with similar weight were randomly divided into four groups,with eight replicates in each group and three rabbits in each replicate.The four experimental groups used soybean husk,rice straw,peanut seedling,and alfalfa as the only fiber source to prepare full-price diets.The pre-test period was seven days,and the formal test period was 30 days.The results showed that the final weight and average daily gain of soybean husk group,peanut seedling group,and alfalfa group were significantly higher than those of the straw group(P<0.05),and the average daily feed intake of the straw group,peanut seedling group,and alfalfa group was significantly higher than that of soybean husk group(P<0.05).The live weight before slaughter of soybean husk group,peanut seedling group,and alfalfa group was significantly higher than that of straw group(P<0.05),and the carcass weight,semi eviscerated weight,and eviscerated weight of peanut seedling group and alfalfa group were significantly higher than those of straw group(P<0.05).The liver index of alfalfa group was significantly higher than that of other groups(P<0.05),and the index of round sac was significantly higher than that of soybean husk group and peanut seedling group(P<0.05).The serum glutathione peroxidase(GSH-Px)activity in the soybean husk group was significantly higher than that in the other groups(P<0.05).The study indicates that alfalfa has the best comprehensive performance as a fiber source for rabbit diet,and peanut seedlings is second only to alfalfa and better than soybean husk and straw.
