补充黑兵 (BSF) 和黄粉 (YMW) 幼虫并没有对子肠道健康或生长产生负面影响. 这些昆虫幼虫改善了免疫状态,并改变了莫斯科的肠道微生物群组成.
科学领域:
- 动物科学动物科学
- 营养科学 营养科学
- 胃肠病学 胃肠病学
背景情况:
- 像黑兵 (BSF) 和黄虫 (YMW) 这样的昆虫被探索为新的料成分.
- 了解它们对家禽肠道健康的影响对于可持续水产养殖至关重要.
- 这项研究调查了活生生的BSF和YMW幼虫对莫斯科的肠道生理学和免疫学的影响.
研究的目的:
- 评估活生生的黑兵 (BSF) 和黄粉 (YMW) 幼虫对莫斯科肠健康的营养模式的影响.
- 评估对肠道组织形态测量,粘素组成,细胞因子表达和肠道微生物群的影响.
- 确定补充昆虫幼虫是否会影响生长性能和肠道参数.
主要方法:
- 126只三天大的雌性莫斯科被食基本饮食,基本饮食+5%的BSF幼虫,或基本饮食+5%的YMW幼虫.
- 在整个52天的实验期内,监测了生长表现.
- 肠道组织,脏,肝脏,胸腺和毛囊被采集用于组织形态测量;粘素组成和MUC-2表达被通过体化学和rt-qPCR分析;使用16S rRNA基因测序来分析脏微生物群.
主要成果:
- 饮食治疗没有影响子的生长性能或肠道组织形态测量.
- 粘素组成和MUC-2基因表达在各组保持一致,遵循正常的生理梯度.
- 在YMW组中,干白素-6 (IL-6) 水平升高;昆虫幼虫改变了菌群,增加了特定的属,减少了其他属.
结论:
- 补充活的BSF和YMW幼虫并没有影响莫斯科的肠道发育或粘素组成.
- 昆虫幼虫补充剂显示,通过增加IL-6来增强肠道免疫状态的潜力.
- 活昆虫幼虫调节了肠道微生物群的组成,可能有利于短链脂肪酸的生产.

Mechanical and Chemical Digestion in the Small Intestine
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating absorption...
