【摘要】 自2021年进入"无抗时代"后,畜禽生产面临的挑战有增无减。其中多样的应激源将使动物长期处于慢性炎症的亚健康状态,包括抗生素在内的许多具有抗炎效果的药物大多残留严重,造成严重的环境污染并最终危害人类健康。植物提取物因其无毒副作用、低残留、无污染、可再生的独有优势,通过干预促炎性细胞因子关键信号通路和改善消化道菌群结构实现炎症控制,成为改善动物健康状况的优先选择。研究者通过早期基础研究筛选出包括迷迭香提取物、桑叶提取物和天然精油在内的一系列植物提取物对动物的生长性能、肠道菌群、免疫应答和肠道健康方面具有良好的调节作用,有效缓解了动物生产中的各类应激,填补了禁抗后的抗生素优势空白,并且改善了产品品质。更多还原

【Abstract】 Since entering the era of“no antibiotics”, the challenges faced by livestock and poultry breeding have increased severely. Among them, various stressors will cause subhealth state of chronic inflammation for a long time in animals. Most of the anti-inflammatory drugs including antibiotics have serious drug residues, Which will cause serious environmental pollution that harm human health ultimately. Due to its unique advantages of no-toxic side effects, low drug residue, nopollution and renewability, plant extracts become the priority choice for animal inflammation control by the means of intervening the key signaling pathways of pro-inflammatory cytokines and improving the structure of gastrointestinal flora. Base on the early reserch, researchers screened early basic research of a series of plant extracts including rosetial oil. It was found that plant extracts were bene-ficial to animal growth performance, intestinal flo-ra, immune response and intestinal health, and al-so could effectively ease the multiple stressors in animal production process.更多还原
