葛根素对饲喂氧化大豆油肉鸡回肠菌群的影响.

The experiment was to investigate the effect of puerarin on ileal microflora of broilers fed oxidized soybean oil. A total of 360 one-day-old healthy female Yellow-feathered broilers were randomly divided into four groups, fresh soybean oil group, soybean oil + puerarin (750 mg/kg) group, oxidized soybean oil group and oxidized soybean oil + puerarin (750 mg/kg) group, respectively, with six replicates in each group and 15 broilers in each replicate. The experiment lasted for 56 d. The results showed that compared with fresh soybean oil group, Shannon indexes was significantly increased on ileal microflora of 56-day-old broilers in oxidized soybean oil group (P<0.05), Sobs indexes on ileal microflora of 28-day-old broilers was reduced. There was a significant interaction between oxidized soybean oil + puerarin group on Sobs indexes and Chao1 indexes of ileal microflora of 56-day-old broilers (P<0.05). Compared with oxidized soybean oil group, Sobs indexes and Chaol indexes were significantly decreased of on ileal microflora of 56-day-old broilers in oxidized soybean oil + puerarin group (P<0.05). Compared with fresh soybean oil group, the abundance of Bacteroidetes, Synergistetes and Ruminococcaceae_UCG-014 on ileal microflora of 56-day-old broilers in oxidized soybean oil group were increased. The experiment indicates that puerarin can reduce number of specific OTUs on ileal microflora of broilers fed with oxidized soybean oil, alleviate imbalance of intestinal microbiota caused by feeding oxidized soybean oil.
