摘要

Seventy five pigs [(Landrace ?? Yorkshire) ?? Duroc] with an initial body weight of 23.3?±1.40 kg were used in the present study to investigate the influence of supplementation of a Bacillus spp. combination as probiotic (0%, 0.01%, and 0.02% with basal diet) in growing-finishing pig diets on performance parameters with a feeding trial period of 16 weeks. Growth performance was analyzed at the start and at weeks 6, 12, and 16 of the experimental period. The entire experiment using probiotic supplementation in the diet revealed significant differences in average daily gain and gain:feed, but no effects on average daily feed intake. The result showed significant effects on digestibility of dry matter (0.002), nitrogen (0.069), and energy (0.099) at week 16; and number of fecal Lactobacillus (0.082, 0.041), E. coli (0.097, 0.052), and blood glucose (0.001, 0.049) at weeks 6 and 16. Dietary supplementation with Bacillus spp. probiotic resulted in a significant linear effect on sensory evaluation of meat color, drip loss at day 3, and carcass weight in pigs. In contrast, there was no significant difference in blood metabolic profiles and noxious gas emissions in this experiment. Dietary combination of Bacillus spp. can be used as a probiotic for enhancing the growth performances and carcass quality of growing-finishing pigs.

Yorkshire）??本研究使用初始体重为23.3？±1.40 kg的Duroc]来研究补充芽孢杆菌的影响。在生长肥育猪日粮中按性能参数组合益生菌（基础日粮分别为0％，0.01％和0.02％），饲喂试验期为16周。在实验期间的开始以及第6、12和16周分析生长性能。在饮食中使用益生菌补充剂的整个实验表明，平均日增重和增益：饲料具有显着差异，但对日均采食量没有影响。结果表明，第16周对干物质（0.002），氮（0.069）和能量（0.099）的消化率具有显着影响;在第6和16周时的粪便乳酸菌（0.082，0.041），大肠杆菌（0.097，0.052）和血糖（0.001，0.049）的数量和数量。益生菌对猪肉的肉色，第3天的滴水损失和car体重量的感官评估产生显着的线性影响。相反，在该实验中，血液代谢特征和有害气体排放没有显着差异。芽孢杆菌属的饮食组合。可作为益生菌用于增强生长肥育猪的生长性能和car体质量。
