本试验旨在研究沙棘果渣提取物(SBPE)对饲喂氧化大豆油黄羽肉鸡屠宰性能、肉品质、肝脏抗氧化指标、肠道黏膜形态结构、盲肠内容物挥发性脂肪酸(VFA)含量和回肠微生物的影响.试验采用超高效液相色谱-串联质谱(UPLC-MS/MS)法对SBPE活性成分进行定性分析,然后选取400只健康、平均体重为39 g的1日龄黄羽肉鸡,随机分成5组,每组10个重复,每个重复8只鸡(公母各占1/2).空白对照组(BC组)饲喂含普通大豆油的基础饲粮,氧化对照组(OX组)饲喂含氧化大豆油的基础饲粮,3个SBPE组分别饲喂在OX组基础饲粮的基础上添加 0.1%(0.1%SBPE 组)、0.2%(0.2%SBPE 组)和 0.4%SBPE(0.4%SBPE 组)的饲粮.试验期63 d.结果表明:1)SBPE中主要含黄酮类、木脂素类、萜类、生物碱类及酚类化合物等多种生物活性成分.2)各组间肉鸡屠宰性能指标、肝脏抗氧化指标以及盲肠内容物VFA含量均无显著差异(P>0.05).3)0.2%SBPE组肉鸡胸肌剪切力显著高于OX组(P<0.05).4)0.2%SB-PE组肉鸡空肠绒毛高度显著高于BC组和OX组(P<0.05).5)与BC组相比,OX组肉鸡回肠微生物Chao1指数和操作分类单元(OTUs)数目显著降低(P<0.05);与OX组相比,0.1%SBPE组回肠微生物Chao1指数和OTUs数目极显著提高(P<0.01).6)在门水平上,与BC组相比,0.2%SBPE组和0.4%SBPE组肉鸡回肠厚壁菌门(Firmicutes)相对丰度显著提高(P<0.05),3个SBPE组回肠变形菌门(Proteobacteria)相对丰度均显著降低(P<0.05).在属水平上,与BC组相比,0.2%SBPE组和0.4%SBPE组肉鸡回肠乳杆菌属(Lactobacillus)相对丰度极显著提高(P<0.01);与OX组相比,0.2%SBPE组回肠乳杆菌属相对丰度显著提高(P<0.05),各SBPE组回肠狭义梭菌属1(Clostridium_sensu_stricto_1)相对丰度均显著降低(P<0.05).由此可知,SBPE能够缓解氧化大豆油造成的黄羽肉鸡肉品质下降和肠道氧化损伤,提高肠道微生物物种丰富度,并提高肠道有益菌相对丰度,降低有害菌相对丰度,维持肠道健康.
Effects of Sea Buckthorn Pomace Extract on Slaughter Performance,Meat Quality,Antioxidant Capability and Intestinal Health of Yellow-Feathered Broilers Fed Oxidized Soybean Oil
This experiment was conducted to investigate the effects of sea buckthorn pomace extract(SBPE)on slaughter performance,meat quality,liver antioxidant indices,intestinal mucosal morphology and structure,volatile fatty acid(VFA)content in cecal content and ileal microbiota of yellow-feather broilers fed oxidized soybean oil.Ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)meth-od was used to qualitatively analyze the active components of SBPE.A total of 400 healthy 1-day-old yellow-feathered broilers with an average body weight of 39 g were randomly divided into 5 groups with 10 replicates per group and 8 chickens per replicate(half male and half female).Broilers in the blank control group(BC group)were fed a basal diet containing common soybean oil,those in the oxidized control group(OX group)were fed a basal diet containing oxidized soybean oil,and those in the three SBPE groups were fed the basal di-et supplemented with 0.1%(0.1%SBPE group),0.2%(0.2%SBPE group)and 0.4%SBPE(0.4%SBPE group)in OX group,respectively.The experiment lasted for 63 days.The results showed as follows:1)SB-PE mainly contained flavonoids,lignans,terpenes,alkaloids,phenols and other bioactive components.2)There were no significant differences in slaughter performance indices,liver antioxidant indices and VFA con-tent in cecal content of broilers among all groups(P>0.05).3)The shear-force in breast muscle of broilers in 0.2%SBPE group was significantly higher than that in OX group(P<0.05).4)The villus height in jejunum of broilers in 0.2%SBPE group was significantly higher than that in BC group and OX group(P<0.05).5)Compared with BC group,the Chao1 index and number of operational taxonomic units(OTUs)in ileal micro-biota of broilers in OX group were significantly decreased(P<0.05);compared with OX group,the Chao1 index and number of OTUs in ileal microbiota in 0.1%SBPE group were extremely significantly increased(P<0.01).6)At the phylum level,compared with BC group,the Firmicutes relative abundance in ileal microbiota of broilers in 0.2%SBPE group and 0.4%SBPE group was significantly increased(P<0.05),and the Pro-teobacteria relative abundance in ileal microbiota in the three SBPE groups was significantly decreased(P<0.05).At the genus level,compared with BC group,the Lactobacillus relative abundance in ileal microbiota of broilers in 0.2%SBPE group and 0.4%SBPE group was extremely significantly increased(P<0.01);com-pared with OX group,the Lactobacillus relative abundance in ileal microbiota in 0.2%SBPE group was signifi-cantly increased(P<0.05),and the Clostridium_sensu_stricto_1 relative abundance in ileal microbiota in all SBPE groups was significantly decreased(P<0.05).In conclusion,SBPE can alleviate the degradation of meat quality and intestinal oxidative damage of yellow-feathered broilers caused by oxidized soybean oil,im-prove the species richness of intestinal microbiota,and improve the relative abundance of beneficial bacteria and reduce the relative abundance of harmful bacteria,so as to maintain intestinal health.[Chinese Journal of Animal Nutrition,2024,36(9):5656-5668]
