谷氨酸亚铁(Ferrous Glutamate):改善家禽肠道屏障功能发表时间:2025-06-14 18:33 有研究称,家禽的总体生长和健康状况与肠道健康状况密切相关,这与肠道屏障功能和肠道微生物群有关。因此,可以通过调整营养策略来改善家禽的肠道健康,例如增强肠道屏障功能和调节微生物群组成,从而提高家禽的生长性能。据研究表明,从肠道形态参数来看,添加谷氨酸亚铁(Ferrous Glutamate)显著增加了绒毛高度(VH)以及绒毛高度与隐窝深度的比值(V:C)。肠道绒毛作为营养物质吸收的重要场所,其高度的增加和 V:C 比值的提升,扩大了营养物质的吸收面积,促进了营养物质的吸收。同时,谷氨酸亚铁(Ferrous Glutamate)还能调节肠道屏障相关基因的表达。它显著上调了紧密连接蛋白相关基因如闭合蛋白 - 1(ZO - 1)、闭合蛋白 - 2(ZO - 2)、黏蛋白 2(MUC2)和溶菌酶(LYZ)的表达水平,而下调了 claudin - 2(CLDN2)和闭合蛋白(OCLN)在空肠中的 mRNA 表达。这些基因的合理调节,使得肠道屏障的完整性得到增强,有效阻止了病原体的入侵,减少了肠道疾病的发生概率。与一些可能带来环境污染的养殖添加剂不同,谷氨酸亚铁(Ferrous Glutamate)在提升养殖效益的同时,不会对环境造成额外负担。其在动物体内的代谢过程相对简单,减少了对土壤和水源可能产生的污染风险,符合当下绿色养殖的发展理念。

Ferrous Glutamate: Improving the Intestinal Barrier Function of Poultry
Studies suggest that the overall growth and health of poultry are closely linked to intestinal health, which is associated with intestinal barrier function and gut icrobiota. Therefore, adjusting nutritional strategies, such as enhancing intestinal barrier unction and modulating microbiota composition, can improve poultry intestinal health and ultimately boost growth performance. Research indicates that in terms of intestinal morphological parameters, the addition of Ferrous Glutamate significantly increases the villus height (VH) and the ratio of villus height to crypt depth (V:C). As key sites for nutrient absorption, taller intestinal villi and a higher V:C ratio expand the absorption area, thereby promoting nutrient uptake. Moreover, Ferrous Glutamate regulates the expression of genes related to the intestinal barrier. It significantly upregulates the expression levels of tight junction - associated genes, including zonula occludens - 1 (ZO - 1), zonula occludens - 2 (ZO - 2), mucin 2 (MUC2), and ysozyme (LYZ), while downregulating the mRNA expression of claudin - 2 (CLDN2) and occludin (OCLN) in the jejunum. This coordinated regulation of genes strengthens the integrity of the intestinal barrier, effectively preventing pathogen invasion and reducing the risk of intestinal diseases. Unlike certain additives that may harm the environment, Ferrous Glutamate enhances farming efficiency without imposing additional ecological burdens. Its relatively simple metabolic pathway in animals minimizes potential pollution risks to soil and water sources, aligning with the principles of sustainable green farming.
