摘要： 为研究枯草芽胞杆菌、酵母菌和乳酸菌三者组合的复合益生菌对早期断奶仔猪生长性能和体液免疫水平的影响,选取“杜×长×大”三元杂交断奶仔猪40头,分为对照组、试验A组、试验B组和试验C组,每组10头,试验A组、试验B组和试验C组与基础饲粮按质量比分别添加1.0‰、2.0‰和3.0‰复合益生菌,对照组不添加复合益生菌,以评价复合益生菌对早期断奶仔猪生长性能、免疫器官指数、血液生理指标和血清生化指标的影响。结果表明,试验B组和试验C组末重极显著高于试验A组和对照组(P<0.01),试验C组平均日增重极显著高于试验A组、试验B组和对照组(P<0.01),对照组和试验B组腹泻率极显著高于试验A组和试验C组(P<0.01);在免疫器官指数上,试验B组、试验C组和对照组腹股沟淋巴结指数显著高于试验A组(P<0.05),试验A组、试验B组脾脏指数显著高于试验C组(P<0.05),试验各组肾脏指数均显著高于对照组(P<0.05),试验A组胸腺指数显著高于试验B组和试验C组(P<0.05);在生理水平上,试验组仔猪血液中,中间粒细胞比率、粒细胞比率、中间细胞数量、粒细胞数量、红细胞数量、血红蛋白、红细胞平均体积以及血小板数量低于对照组,且大部分指标表现为差异显著(P<0.05),淋巴细胞比率高于对照组,但差异不显著(P>0.05);在生化水平上,试验B组和试验C组谷草转氨酶含量显著高于对照组和试验A组(P<0.05)。试验结果表明,枯草芽胞杆菌、酵母菌、乳酸菌三者组合的复合益生菌与基础饲粮混合可提高早期断奶仔猪生长性能和体液免疫功能。

Abstract: The objective of this study was to assess the effects of dietary compound probiotics prepared with Bacillus subtilis, yeast and lactic acid bacteria on growth performance and humoral immunity of early-weaned piglets. A total of 40 three way crossbred [Duroc×(Landrace×Yorkshire)] weaned piglets were averagely and randomly assigned into four groups. The basal diet of experimental groups A, B and C were supplemented with 1.0‰, 2.0‰ and 3.0‰ compound probiotics, respectively. The control group received no dietary supplementation. The indices associated with growth performance, immune organ index, and blood physiological and biochemical parameters of the piglets in different groups were statistically evaluated. The results showed that at the end of the experiment, the body weight of experimental groups B and C was significantly higher than experimental group A and control group (P<0.01), the average daily gain of experimental group C was significantly higher than experimental groups A, B and control group (P<0.01), the diarrhea incidence of experimental group B and control group was significantly higher than experimental groups A and C (P<0.01);in terms of immune organ index, experimental groups B, C and control group had significantly higher inguinal lymph node index compared to experimental group A (P<0.05), experimental groups A and B had significantly higher spleen index compared to experimental group C (P<0.05), experimental groups A, B and C had significantly higher kidney index compared to control group (P<0.05), experimental groups A had significantly higher thymus index compared to experimental groups B and C (P<0.05);for blood physiological parameters, lower values of neutrophils and granulocyte proportion, neutrophils, granulocytes and erythrocytes number, hemoglobin and mean corpuscular volume, and platelet count were observed in the three experimental groups compared to control group, and the significant differences in most of the parameters between the three experimental groups and control group were found (P<0.05), while the value of lymphocyte ratio of the three experimental groups was higher than control group, no significant difference was observed (P>0.05);in respect of blood biochemical parameters, the content of glutamate oxaloacetate transaminase was found significantly elevated in experimental groups B and C compared to experimental group A and control group (P<0.05). Collectively, these data reveal that dietary supplementation of compound probiotics prepared with Bacillus subtilis, yeast and lactic acid bacteria is able to improve the growth performance and humoral immunity of early-weaned piglets.
