Practical evidence suggests possible beneficial effects with the combined use of prebiotics and probiotics which can improve production parameters. The objective of the study was to investigate the addition of Saccharomyces cerevisiae (SC) as prebiotic and the combination of Lactobacillus spp. (L), Bacillus spp. (B) as probiotics on productive parameters and economic feasibility. Four hundred male pigs, hybrids of commercial genetic lines (Pietrain), were used: T1 = control group, T2 = 4 kg/tonne SC, T3 = 0.8 kg/tonne feed L and B, T4 = 4 kg/tonne SC + 0.8 kg/tonne L and B. Productive parameters were recorded in the treatment groups for four periods. Then, the viscera of five pigs per treatment were collected after slaughter to evaluate the histological changes and cytokine concentrations in the ileum. The weight gains of groups at 70-100, 100-125 and 125-150 days in the T4 group showed statistically increases (p < .05). Feed intake had a significant difference (p < .05) in T3 versus T1. The feed-conversion ratio improved for all periods in the T4 group (p < .05). The eosinophil, mononuclear infiltration and cytokines (tumor necrosis factor-α and interleukin-6) in the mucosa were lower for treatments with probiotics. In conclusion, there was an economic benefit when using both prebiotics and probiotics in the diet of pigs from weaning to finishing.
实践证据表明，益生元与益生菌联合使用可能具有有益效果，可改善生产参数。本研究的目的是调查添加酿酒酵母（SC）作为益生元以及乳酸杆菌属（L）、芽孢杆菌属（B）作为益生菌对生产参数和经济可行性的影响。使用了400头商业遗传品系（皮特兰）杂交的雄性猪：T1 = 对照组，T2 = 4千克/吨SC，T3 = 0.8千克/吨饲料L和B，T4 = 4千克/吨SC + 0.8千克/吨L和B。在四个时期记录治疗组的生产参数。然后，屠宰后收集每个处理五只猪的内脏，以评估回肠的组织学变化和细胞因子浓度。T4组在70 - 100天、100 - 125天和125 - 150天的体重增加显示出统计学上的增加（p < 0.05）。T3组与T1组的采食量有显著差异（p < 0.05）。T4组在所有时期的饲料转化率均有所改善（p < 0.05）。益生菌处理组的黏膜中嗜酸性粒细胞、单核细胞浸润和细胞因子（肿瘤坏死因子-α和白细胞介素-6）较低。总之，从断奶到育肥阶段，在猪的日粮中同时使用益生元和益生菌具有经济效益。
