摘 要:
旨在研究添加不同剂量的发酵乳酸杆菌F-6对肉鸡血清抗氧化性能及肠道VFA含量的影响。选择健康的1日龄AA肉仔鸡240只,称重后随机分为4组,各组肉仔鸡的初始体重差异均不显著(P>0.05)。各组肉仔鸡基础日粮一致,3个试验组在饮水中添加发酵乳酸杆菌F-6,添加剂量分别为2.0×10~5、2.0×10~6、1.0×10~7CFU/m L,对照组肉仔鸡不饲喂发酵乳酸杆菌。于21日龄及42日龄时,分别测定各组肉鸡血清中的MDA和SOD含量,以及肠道中VFA含量。结果表明:21日龄时,试验3组肉鸡血清中的SOD含量显著高于对照组(P<0.05);42日龄时,试验2组和3组肉鸡血清中的SOD含量也显著高于对照组(P<0.05)。21日龄和42日龄时,各试验组肉鸡盲肠及回肠中的乙酸和总挥发性脂肪酸(TVFA)含量均显著高于对照组(P<0.05);除试验1组外,其他各试验组肉鸡的回肠及盲肠丁酸含量均显著高于对照组(P<0.05)。综上提示,发酵乳酸杆菌F-6能够显著提高肉鸡的血清抗氧化性能及肠道部分VFA含量,其具有开发为新型饲料益生菌添加剂的应用前景。

摘 要:
This experiment was conducted to assess the supplementation of Lactobacillus fermentum F-6 with different levels in basal diet on serum antioxidant capacity and volatile fatty acid(VFA) in intestine of broiler chickens. A total of 240 1-day-old healthy AA broiler chickens were included in this study and were randomly divided into 4 groups(3 experimental groups and 1control group). No significant differences were observed in initial body weight between the chickens of different groups(P>0.05).The same basal diet was supplied for each group; however, the basal diet of the three experimental groups was supplemented with2.0×10~5, 2.0×10~6 and 1.0×10~7 CFU/m L of Lactobacillus fermentum F-6, respectively. No additions of Lactobacillus fermentum F-6 were made in basal diet of the control group. The serum content of MDA and SOD as well as content of VFA in intestine of 21-day-old and 42-day-old broiler chickens in each group were determined. The results showed that the serum content of SOD of21-day-old chickens of experimental group 3 was significantly higher than that of control group(P<0.05); the serum content of SOD of 42-day-old chickens in experimental group 2 and 3 were significantly higher than that in control group(P<0.05); the content of acetic acid and total volatile fatty acid(TVFA) in cecum and ileum of 21-day-old and 42-day-old broiler chickens of all experimental groups were significantly higher than that in control group(P<0.05); except for experimental group 1, the content of butyrate in cecum and ileum of 21-day-old and 42-day-old broiler chickens of the other experimental groups were significantly higher than that of control group(P<0.05). It was demonstrated that the supplementation of Lactobacillus fermentum F-6 in basal diet was able to improve the serum antioxidant capacity and increase the level of VFA in intestine of broiler chickens, which was potential to be developed as a new type of additive.
