植物精油对西门塔尔公牛血清抗氧化性能和直肠微生物的影响
Effects of plant essential oils on antioxidant activity and rectal microorganisms of Simmental bulls
摘要
Abstract
The purpose of the experiment was to study the effects of plant essential oils(PEO)on the antioxidant activity of serum and rectal microorganisms in Simmental bulls.Fifty-six Simmental bulls weighing(564.39±7.09)kg were randomly divided into four groups,with 14 repeats in each group and one bull in each repeat.The control group(CK)was fed with basal diet,while the treatment group was fed with 0.5(PEO1),1.0(PEO2)and 1.5(PEO3)g/(head·d)of PEO in basal diet,respectively.The pre-feeding period was seven days,and the formal trial period was 60 days.The results showed that T-AOC in PEO2 group was significantly higher than that in CK group on the 30th day(P＜0.05).On the 60th day,the content of MDA in PEO2 group and PEO3 group was significantly lower than that in CK group(P＜0.05),and the activity of CAT in PEO2 group and PEO3 group was significantly higher than that in CK group and PEO1 group(P＜0.05).PEO had no significant effect on Chao1,Observed_Species,Shannon,and Simpson(P＞0.05).At the level of rectal microbial phyla,PEO had no significant effect on the relative abundance of each phyla(P＞0.05).At the level of rectal microbiology,the relative abundance of Veillonellaceae in PEO1 group was significantly lower than that in CK group(P＜0.05).The relative abundance of Christensenellaceae in PEO2 group was significantly higher than that in CK group,PEO1 group,and PEO3 group(P＜0.05).At the level of rectal microbial genus,the relative abundance of Prevotella in PEO3 group was significantly higher than that in CK group and PEO2 group(P＜0.05).The relative abundance of Butyrivibrio in PEO2 group was significantly higher than that in CK group,PEO1 group,and PEO3 group(P＜0.05).The study indicates that the addition of PEO to the diet of Simmental bulls can improve the antioxidant activity and the structure of intestinal microbial community,and the suitable addition of PEO is 1.0 g/(head·d).关键词
