Why add yeast cell walls to feed

Why add yeast cell walls to feed为什么要在饲料中加入酵母细胞壁

The main reasons for adding yeast cell walls to feed are as follows:在饲料中添加酵母细胞壁的主要原因如下：

1、 Enhance animal immunity1、增强动物免疫力

Immune regulatory effect 免疫调节作用

      The main components of yeast cell wall are β - glucan and mannan. β - glucan is an effective immune modulator that can activate macrophages in animals. Macrophages are important cells of the immune system that, once activated, can engulf and eliminate pathogens such as bacteria, viruses, etc. For example, in young animals, their own immune system is not yet fully developed, and adding yeast cell walls can help them better resist the invasion of external pathogens.酵母细胞壁的主要成分是β -葡聚糖和甘露聚糖。β -葡聚糖是一种有效的免疫调节剂，可激活巨噬细胞。巨噬细胞是免疫系统的重要细胞，一旦被激活，就能吞噬和消灭细菌、病毒等病原体。例如，在幼龄动物中，它们自身的免疫系统尚未发育完全，添加酵母细胞壁可以帮助它们更好地抵抗外部病原体的入侵。

      Mannan can bind to lectins on the surface of pathogens such as bacteria and viruses, preventing them from binding to receptors on animal intestinal epithelial cells. This is like setting up a barrier between pathogens and animal cells, reducing the chance of pathogens infecting animals.甘露聚糖可以与细菌和病毒等病原体表面的凝集素结合，阻止它们与动物肠上皮细胞上的受体结合。这就像在病原体和动物细胞之间建立一道屏障，减少病原体感染动物的机会。

Improve antibody levels 提高抗体水平

      Yeast cell walls can stimulate the animal's immune system to produce more antibodies. Antibodies are protein molecules used in animals to recognize and neutralize foreign pathogens. For example, in poultry farming, adding yeast cell walls can increase the level of avian influenza antibodies, enhance the resistance of poultry to avian influenza virus, and thereby reduce the risk of avian infection.酵母细胞壁可以刺激动物的免疫系统产生更多抗体。抗体是动物体内用于识别和中和外来病原体的蛋白质分子。例如，在家禽养殖中，添加酵母细胞壁可以提高禽流感抗体的水平，增强家禽对禽流感病毒的抵抗力，从而降低禽类感染的风险。

2、 Improving the intestinal health of animals2、改善动物肠道健康

Maintain the balance of gut microbiota维持肠道菌群平衡

      The mannan in the yeast cell wall can selectively promote the growth of beneficial bacteria such as bifidobacteria and lactobacilli. These beneficial bacteria can ferment in the intestine to produce organic acids such as lactic acid, which lowers the pH value of the intestine. Acidic environment is not conducive to the growth of harmful bacteria such as Escherichia coli and Salmonella, thus maintaining the ecological balance of gut microbiota.酵母细胞壁中的甘露聚糖可以选择性地促进双歧杆菌和乳酸菌等有益菌的生长。这些有益菌可以在肠道内发酵，产生乳酸等有机酸，从而降低肠道的pH值。酸性环境不利于大肠杆菌、沙门氏菌等有害菌的生长，从而维持肠道菌群的生态平衡。酵母细胞壁中的甘露聚糖可以选择性地促进双歧杆菌和乳酸菌等有益菌的生长。这些有益菌可以在肠道内发酵，产生乳酸等有机酸，从而降低肠道的pH值。酸性环境不利于大肠杆菌、沙门氏菌等有害菌的生长，从而维持肠道菌群的生态平衡。

      At the same time, yeast cell walls serve as prebiotics, providing nutrients for beneficial bacteria and facilitating their colonization and reproduction in the intestine. For example, adding yeast cell walls during pig feeding can help establish a healthy gut microbiota and reduce the occurrence of intestinal diseases such as diarrhea.同时，酵母细胞壁作为益生元，为有益细菌提供营养，促进它们在肠道内的定植和繁殖。例如，在猪饲养过程中添加酵母细胞壁有助于建立健康的肠道菌群，减少腹泻等肠道疾病的发生。同时，酵母细胞壁作为益生元，为有益细菌提供营养，促进它们在肠道内的定植和繁殖。例如，在猪饲养过程中添加酵母细胞壁有助于建立健康的肠道菌群，减少腹泻等肠道疾病的发生。

Protecting the intestinal mucosal barrier保护肠黏膜屏障保护肠黏膜屏障

      Yeast cell walls can enhance the integrity of intestinal mucosa. It can stimulate intestinal epithelial cells to secrete mucus, which can prevent harmful substances from directly contacting intestinal mucosal cells. Moreover, it can promote the expression of tight junction proteins between intestinal mucosal cells, making the barrier function of intestinal mucosa more stable. For example, in aquaculture, factors such as changes in water quality can easily damage the intestinal mucosa of fish. Adding yeast cell walls can alleviate this damage and improve the intestinal health of fish.酵母细胞壁可以增强肠黏膜的完整性。能刺激肠上皮细胞分泌粘液，防止有害物质直接接触肠粘膜细胞。促进肠粘膜细胞间紧密连接蛋白的表达，使肠粘膜的屏障功能更加稳定。例如，在水产养殖中，水质变化等因素很容易损伤鱼类的肠黏膜。添加酵母细胞壁可以减轻这种损害，改善鱼类的肠道健康。酵母细胞壁可以增强肠黏膜的完整性。能刺激肠上皮细胞分泌粘液，防止有害物质直接接触肠粘膜细胞。促进肠粘膜细胞间紧密连接蛋白的表达，使肠粘膜的屏障功能更加稳定。例如，在水产养殖中，水质变化等因素很容易损伤鱼类的肠黏膜。添加酵母细胞壁可以减轻这种损害，改善鱼类的肠道健康。

3、 Adsorption of fungal toxins3、真菌毒素的吸附3、真菌毒素的吸附

Toxin binding ability 毒素结合能力

      The components in yeast cell walls, especially glucans and mannans, have the function of adsorbing fungal toxins. Fungal toxins are toxic secondary metabolites produced by fungi, such as aflatoxin and zearalenone. These toxins can cause damage to organs such as the liver and kidneys of animals, affecting their growth performance and health.酵母细胞壁中的成分，特别是葡聚糖和甘露聚糖，具有吸附真菌毒素的功能。真菌毒素是真菌产生的次生代谢产物，如黄曲霉毒素和玉米赤霉烯酮。这些毒素会对动物的肝脏和肾脏等器官造成损害，影响它们的生长性能和健康。酵母细胞壁中的成分，特别是葡聚糖和甘露聚糖，具有吸附真菌毒素的功能。真菌毒素是真菌产生的次生代谢产物，如黄曲霉毒素和玉米赤霉烯酮。这些毒素会对动物的肝脏和肾脏等器官造成损害，影响它们的生长性能和健康。

      The yeast cell wall can bind to mycotoxins through its complex chemical structure, forming stable complexes that reduce animal absorption of mycotoxins. For example, in situations where feed ingredients are prone to fungal contamination, adding yeast cell walls can effectively reduce the risk of animals ingesting mycotoxins and ensure their health.酵母细胞壁可以通过其复杂的化学结构与真菌毒素结合，形成稳定的复合物，减少动物对真菌毒素的吸收。例如，在饲料成分容易受到真菌污染的情况下，添加酵母细胞壁可以有效降低动物摄入真菌毒素的风险，并确保其健康。酵母细胞壁可以通过其复杂的化学结构与真菌毒素结合，形成稳定的复合物，减少动物对真菌毒素的吸收。例如，在饲料成分容易受到真菌污染的情况下，添加酵母细胞壁可以有效降低动物摄入真菌毒素的风险，并确保其健康。
