A feeding expriment was performed to investigate the effects of dietary supplementation with Brevibacillus brevis FJAT-1501-BPA fermentation on the growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets. A total of 150 weaned piglets were randomly assigned to different treatments groups, which were fed the same basic diet supplemented with 10, 1, 0.1, 0.01 and 0 % B. brevis FJAT-1501-BPA fermentation. The results showed that a diet supplemented with 10 % B. brevis FJAT-1501-BPA fermentation could significantly increase the final body weight (P < 0.05) and decrease feed to gain ratio, which was 37.1 % lower than that of the control group. The addition of B. brevis FJAT-1501-BPA exhibited a trend of reducing the contents of the Escherichia coli, Lactobacillus and Salmonella compared with the control. During the 35 day experimental period, cellulase and protease activities were significantly increased by the dietary inclusion of the B. brevis FJAT-1501-BPA fermentation (P < 0.05). The cellulase activity for piglets fed diet containing 1 % B. brevis FJAT-1501-BPA fermentation, 21.8 U/g, was highest among the different treatments. The protease activity for piglets fed diet containing 10 % B. brevis FJAT-1501-BPA fermentation, 50.4 U/g, was highest among the different treatments. The amylase and hemicellulase activities for piglets fed diet containing 10 % B. brevis FJAT-1501-BPA fermentation were significantly higher than those on the control diet and other treatments (P < 0.05). Moreover, usage of feed dietary supplementation with B. brevis FJAT-1501-BPA had positive effects on levels of enzymes and minerals in blood. The alkaline phosphatase, alanine aminotransferase, Fe and Mg concentrations for weaned piglets fed diet containing B. brevis FJAT-1501-BPA fermentation were significantly higher than for those on the control diet (P < 0.05). Furthermore, concentration of IgG in serum was higher in weaned piglets fed diet containing 1 % B. brevis FJAT-1501-BPA fermentation compared to other treatments. These results indicated that feeding with B. brevis FJAT-1501-BPA has the potential to improve growth performance, faecal microflora, faecal enzyme activities and blood parameters of weaned piglets.
进行了一项饲养实验，以研究添加短短芽孢杆菌FJAT - 1501 - BPA发酵物对断奶仔猪生长性能、粪便微生物群落、粪便酶活性和血液参数的影响。总共150头断奶仔猪被随机分配到不同的处理组，分别饲喂添加了10%、1%、0.1%、0.01%和0%短短芽孢杆菌FJAT - 1501 - BPA发酵物的相同基础日粮。结果表明，添加10%短短芽孢杆菌FJAT - 1501 - BPA发酵物的日粮可显著增加最终体重（P < 0.05）并降低料重比，比对照组低37.1%。与对照组相比，添加短短芽孢杆菌FJAT - 1501 - BPA有降低大肠杆菌、乳酸杆菌和沙门氏菌含量的趋势。在35天的实验期内，日粮中添加短短芽孢杆菌FJAT - 1501 - BPA发酵物显著提高了纤维素酶和蛋白酶活性（P < 0.05）。在不同处理中，饲喂含1%短短芽孢杆菌FJAT - 1501 - BPA发酵物日粮的仔猪纤维素酶活性最高，为21.8 U/g。饲喂含10%短短芽孢杆菌FJAT - 1501 - BPA发酵物日粮的仔猪蛋白酶活性最高，为50.4 U/g。饲喂含10%短短芽孢杆菌FJAT - 1501 - BPA发酵物日粮的仔猪淀粉酶和半纤维素酶活性显著高于对照组日粮和其他处理组（P < 0.05）。此外，日粮中添加短短芽孢杆菌FJAT - 1501 - BPA对血液中的酶和矿物质水平有积极影响。饲喂含短短芽孢杆菌FJAT - 1501 - BPA发酵物日粮的断奶仔猪碱性磷酸酶、谷丙转氨酶、铁和镁的浓度显著高于对照组日粮的仔猪（P < 0.05）。此外，与其他处理组相比，饲喂含1%短短芽孢杆菌FJAT - 1501 - BPA发酵物日粮的断奶仔猪血清中IgG浓度更高。这些结果表明，饲喂短短芽孢杆菌FJAT - 1501 - BPA有改善断奶仔猪生长性能、粪便微生物群落、粪便酶活性和血液参数的潜力。
