摘要

杜仲(CAE)富含绿原酸(CGA)的提取物因其对牲畜的肠道健康和抗氧化作用而闻名。本研究探讨了围着床期添加CAE对母猪繁殖性能和肠道微生物群的影响。选用60头东辽黑母猪,从妊娠第5天至第15天,随机分为不添加CAE(对照组)和每天添加600或2000 mg/kg CAE两组。高剂量CAE显著提高母猪血清总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、免疫球蛋白A (IgA)和免疫球蛋白M (IgM)水平,降低丙二醛(MDA)水平。粪便短链脂肪酸(SCFAs)也显著增加。这些变化与生殖性能的提高有关,包括产仔数增加、活产仔猪数量增加、活产仔猪个体出生重增加、活产仔猪总出生重增加以及死亡率降低。粪便微生物群的16S rRNA测序显示,CAE显著改变了微生物的多样性和组成,减少了潜在有害细菌的丰度,但增加了有益细菌的丰度。综上所述,在母猪着床期添加CAE可以减少氧化应激,改变肠道菌群组成,提高母猪繁殖性能,从而提高养殖场的盈利能力。

Effects of Supplementation with Chlorogenic Acid-Rich Extract from Eucommia ulmoides Oliver During Peri-Implantation on the Reproductive Performance and Gut Microbiota of Sows.

Chlorogenic acid (CGA)-rich extracts from Eucommia ulmoides Oliver (CAE) are known for their gut health and antioxidant benefits in livestock. This study examines the effects of CAE supplementation during the peri-implantation period on sow reproductive performance and the gut microbiota. Sixty Dongliao black sows were randomized to receive either no supplementation (control) or CAE at 600 or 2000 mg/kg daily from gestation day -5 through day 15. High-dose CAE intake significantly increased total antioxidant capacity (T-AOC), superoxide dismutase (SOD), catalase (CAT), immunoglobulin A (IgA), and immunoglobulin M (IgM) levels in sow serum but decreased malondialdehyde (MDA) levels. Fecal short-chain fatty acids (SCFAs) also increase significantly. These changes correlate with improved reproductive performance, including a larger litter size, higher numbers of live-born piglets, a greater individual birth weight of live-born piglets, a higher total litter birth weight of live-born piglets, and a lower mortality rate. 16S rRNA sequencing of the fecal microbiota revealed that CAE markedly altered microbial diversity and composition, reducing the abundance of potentially harmful bacteria but increasing the abundance of beneficial bacteria. In conclusion, supplementation with CAE during the peri-implantation phase can reduce oxidative stress, alter the gut microbiota composition, and improve sow reproductive performance, thus potentially increasing breeding farm profitability.
