本试验旨在研究低聚木糖(XOS)对生长肥育猪血浆生化参数、肌肉氨基酸含量和肌纤维类型组成的影响。试验选取70日龄、平均体重约为30 kg的杜×长×大三元杂交猪80头,随机分为8组,每组10个重复(公母各占1 /2) ,每个重复1头猪。试验设对照组、抗生素组、30 ~ 65 kg阶段100、250和500 g /t XOS组以及30 ~ 100 kg阶段100、250和500 g /t XOS组。于试猪平均体重达100 kg时,前腔静脉采血,离心分离血浆,测定生化参数;屠宰后取背最长肌样品,测定其氨基酸含量及肌纤维类型和肌肉生长相关基因mRNA表达量。结果表明: 1)与对照组或抗生素组相比,饲粮添加不同剂量XOS可显著提高血浆球蛋白含量(P

The present study was conducted to investigate the effects of xylo-oligosaccharide (XOS) on plasma biochemical indices,amino acid contents and fiber type composition of muscle of growing-finishing pigs. A total of 80 Duroc×Large White×Landrace pigs with an initial body weight of about 30 kg and at 70 days of age were randomly assigned to 8 groups with 10 replicates per group (half male and half female) and one pig in a replicate. The eight groups included control group,antibiotic group,supplementation groups of 100,250 and 500 g /t XOS during...
