| 中文摘要:为了探讨益生菌复合发酵料对断奶仔猪消化环境、血清生化指标和代谢激素水平的影响，选择遗传背景相似、平均体质量为（8.55±0.59） kg的断奶长×大仔猪120 头，分为2个处理（对照组和试验组），每个处理6 个重复，每个重复10 头；对照组饲喂含抗生素的基础日粮，试验组饲喂90%无抗基础日粮+10%益生菌复合发酵料。分别在仔猪28、44和75 日龄从每个重复中随机选择2 头仔猪采血，进行血清生化和代谢激素指标检测，其中1 头屠宰，进行胃肠液pH测定。结果显示:与对照组相比，试验组断奶仔猪胃肠液pH分别下降12.26% 和9.11%；在44和75 日龄，血清葡萄糖（GLU）浓度分别提高7.63%和3.93%， 甘油三酯（TG） 浓度分别提高25.71%和27.54%，尿素氮（BUN）浓度分别降低7.15%和5.85%，总蛋白（TP）质量浓度分别提高16.20%和15.91%，球蛋白（GLB）质量浓度分别提高87.40%和51.26%；白/球比（A/G）显著降低；试验组谷丙转氨酶（ALT）、谷草转氨酶（AST）和乳酸脱氢酶（LDH）的活性无显著变化，但AST/ALT的比值降低，并在75 日龄达到显著水平；试验组碱性磷酸酶（ALP）活性显著低于对照组；试验组促甲状腺激素（TSH）、甲状腺激素（T4）、三碘甲状腺原氨酸（T3）、胰岛素（INS）和生长激素（GH）的水平变化不显著，但除T4外，其他指标均呈上升趋势。结果表明，添加益生菌复合发酵饲料可以增强断奶仔猪营养素的合成代谢能力，促进营养素在体内的沉积，从而有利于断奶仔猪的生长，提高生产性能和机体免疫力。 |

| Abstract:To investigate effects of probiotics composite fermentation feed on gastrointestinal circumstance,serum biochemical and metabolic hormones indexes of weaning piglets,a total of 120 large-white weaning piglets with average mass of (8.55±0.59) kg were randomly divided into 2 groups(control group and experimental group) with 6 replicates per group and 10 piglets per repetition．Piglets in control group were fed a basal diet with antibiotics,piglets in the treatment groups were fed the 90% basal diet without antibiotics and 10% probiotics composite fermentation feed．Two piglets were randomly selected from each replicate at 28 days, 44 days and 75 days old respectively.Blood biochemical and metabolic hormones were measured.One of them was slaughtered and the gastrointestinal pH was measured.The results showed that,compared with control group,the gastrointestinal pH of weaning piglets in treatment group fell by 12.26% and 9.11% respectively; at 44 d and 75 d of age , GLU concentration increased by 7.63% and 3.93% respectively , TG concentration increased by 25.71% and 27.54% respectively, the concentration of BUN decreased by 7.15% and 5.85% respectively, TP concentration increased by 16.20% and 15.91% respectively, GLB mass concentration increased by 87.40% and 51.26% respectively ; A/G ratio decreased significantly; there were no significant change on the activities of ALT, AST and LDH, but the AST/ALT ratio decreased, and the difference reached significant level at age of 75 days; ALP activity of experimental group was significantly lower than that of control group; there were no significant change on the levels of TSH, T4, T3, INS and GH, but the data in experimental group was superior to the control group to some extent, except the T4, other indexes highlighted rising trends.The results showed that adding probiotics composite fermentation feed could enhance weaning piglets nutrients anabolism ability, promote the nutrients deposition in the body, which promoted the growth of the weaning piglets and the production performance and immunity of the organism. |
