摘要:

旨在探究饲粮中添加槲皮万寿菊素(quercetagetin, QG)对过氧化氢(hydrogen peroxide, H2O2)攻毒肉鸡的屠宰性能、肉品质、血清抗氧化与免疫功能及肠道菌群的影响。试验采用单因素完全随机设计,选取240只1日龄科宝(Cobb)肉鸡,随机分为3组:对照组(饲喂基础饲粮+37日龄腹腔注射1.0 mL·kg-1 BW生理盐水),H2O2组(饲喂基础饲粮+37日龄腹腔注射1.0 mL·kg-1 BW的10% H2O2溶液),QG组(饲喂添加100 mg·kg-1 QG的基础饲粮+37日龄腹腔注射1.0 mL·kg-1 BW的10% H2O2溶液),每组8个重复,每个重复10只鸡。试验期总计42 d。结果表明:1)与对照组相比,H2O2组肉鸡的屠宰率、腿肌率显著降低(P < 0.05);饲粮添加QG使肉鸡的屠宰率、腿肌率与对照组相比均无显著差异(P>0.05)。2)与对照组相比,H2O2组腿肌的红度a*显著降低(P < 0.05),蒸煮损失显著提高(P < 0.05);饲粮添加QG使腿肌的a*和蒸煮损失与对照组相比均无显著差异(P>0.05)。3)与对照组相比,H2O2组肉鸡血清中SOD、GSH-Px、T-AOC、CAT活性和IgA、IgG、C3含量显著降低(P < 0.05),MDA水平和IgM和TNF-α含量显著提高(P < 0.05);但与H2O2组相比,饲粮中添加QG后可显著提高肉鸡血清中SOD、GSH-Px、T-AOC、CAT活性和IgA、C3含量(P < 0.05),并显著降低MDA水平(P < 0.05)。4)厚壁菌门(Firmicutes)、拟杆菌门(Bacteroidota)是肉鸡盲肠门水平的优势门。与对照组相比,H2O2组的厚壁菌门(Firmicutes)相对丰度显著降低(P < 0.05),QG组的拟杆菌属(Bacteroides)相对丰度显著升高(P < 0.05)。综上所述:饲粮添加100 mg·kg-1 QG可以通过提高抗氧化和免疫功能,优化盲肠菌群结构,缓解H2O2诱导的氧化应激对肉鸡屠宰性能和肉品质的不利影响,为QG在肉鸡健康养殖中的科学应用提供理论依据。

Abstract:

This experiment aimed to investigate the effects of adding quercetagetin (QG) to the diet on the slaughter performance, meat quality, serum antioxidant and immune functions, and gut microbiota of broiler chickens challenged with hydrogen peroxide (H2O2). A single-factor completely randomized design was adopted in the experiment. A total of 240 one-day-old Cobb broiler chickens were selected and divided into three groups: the control group (fed a basal diet+intraperitoneal injection of 1.0 mL·kg-1 BW of normal saline at 37 days of age), the H2O2 group (fed a basal diet+intraperitoneal injection of 1.0 mL·kg-1 BW of a 10% H2O2 solution at 37 days of age), and the QG group (fed a basal diet supplemented with 100 mg·kg-1 QG+intraperitoneal injection of 1.0 mL·kg-1 BW of a 10% H2O2 solution at 37 days of age). Each group had 8 replicates, with 10 chickens in each replicate. The experimental period lasted for 42 days in total. The results showed that: 1) Compared with the control group, the slaughter rate and leg muscle rate of broiler chickens in the H2O2 group were decreased (P < 0.05); The addition of QG to the diet led to no significant difference in the slaughter rate and leg muscle rate of broiler chickens compared with the control group (P>0.05). 2) Compared with the control group, the redness (a*) of the leg muscle in the H2O2 group decreased significantly (P < 0.05), and the cooking loss increased significantly (P < 0.05); The addition of QG to the diet resulted in no significantly difference in the a* value and cooking loss of the leg muscle compared with the control group (P>0.05). 3) Compared with the control group, the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), and catalase (CAT), as well as the contents of immunoglobulin A (IgA), immunoglobulin G (IgG), and complement 3 (C3) in the serum of broiler chickens in the H2O2 group were decreased significantly (P < 0.05), while the malondialdehyde (MDA) level and the contents of immunoglobulin M (IgM) and tumor necrosis factor-α (TNF-α) were increased significantly (P < 0.05); However, compared with the H2O2 group, the addition of QG to the diet significantly increased the activities of SOD, GSH-Px, T-AOC, and CAT, as well as the contents of IgA, and C3 in the serum of broiler chickens (P < 0.05), and significantly decreased the MDA level (P < 0.05). 4) Firmicutes and Bacteroidota were the dominant phyla at the phylum level in the cecum of broiler chickens. Compared with the control group, the relative abundance of Firmicutes in the H2O2 group decreased significantly (P < 0.05), and the relative abundance of Bacteroides in the QG group increased significantly (P < 0.05). In conclusion, the addition of 100 mg·kg-1 of QG to the diet can mitigate the adverse effects of H2O2-induced oxidative stress on the slaughter performance and meat quality of broiler chickens by enhancing antioxidant and immune functions and optimizing the structure of the cecal microbiota. This provides a theoretical basis for the scientific application of QG in the healthy farming of broiler chickens.
