日粮中添加包膜丁酸钠对香猪生产性能和血液生化指标的影响

Effect of Coated Sodium Butyrate on Growth Performance and Blood Biochemical Index of Weaning Xiang pig

试验旨在筛选出最优的包膜丁酸钠组方及最佳添加剂量,采用单因素完全随机分组试验设计,将48头断奶小香猪随机分为3组,每组16头。试验分对照组、试验1组(基础日粮+300mg/kg包膜丁酸钠)、试验2组(基础日粮+500mg/kg包膜丁酸钠),研究了包膜丁酸钠对断奶香猪抗腹泻促生长及血液生化指标的影响。结果表明,与对照组相比,包膜丁酸钠可显著提高断奶香猪的料重比(P<0.05),降低断奶仔猪的腹泻率(P<0.05)。白蛋白/球蛋白、IgG和碱性磷酸酶都随日粮中包膜丁酸钠添加量的增加呈现增高的趋势;且日粮中300mg/kg的添加量饲喂效果优于500mg/kg的添加量。

This experiment used the single factor completely randomized experimental design, a total of 72 weaning Xiang pigs were divided into three groups randomly. Every group had 24 heads, a （control group）; basal diet; b： basal diet ＋300 mg/kg coated sodium butyrate~ c： basal diet ＋ 500 mg/kg coated sodium butyrate. Study of compound coated sodium buty rate on weaning Xiang pig growth performance and blood biochemical index influence. The experimental result indicated that~ compared with the control group, the compound coated sodium butyrate could significantly improve feed conversion rate（P〈 0.05）, and significantly reduce weaning Xiang pig＇s diarrhea rate （P〈0.05）. The A/G, GLB, IgG, and AKP were content along with the coated sodium butyrate showed higher increasing in the tendency. It was suggested that adding 300 mg/kg coa- ted sodium butyrate in compound feed of Xiang pig was better than adding 500 mg/kg.
