What are the benefits of adding beer yeast to feed

Adding beer yeast to feed has many benefits, including:在饲料中添加啤酒酵母有很多好处，包括：

1、 Rich in nutrients 1、营养丰富

High protein content: Beer yeast contains abundant protein, with a protein content of about 40% -50%. These proteins contain various essential amino acids required by the animal body, such as lysine, methionine, etc. It is crucial for animal growth and muscle development. For example, adding beer yeast to pig feed can provide high-quality protein sources for pigs, which helps with muscle growth and weight gain.蛋白质含量高：啤酒酵母含有丰富的蛋白质，蛋白质含量约为40% -50%。这些蛋白质含有动物机体所需的各种必需氨基酸，如赖氨酸、蛋氨酸等。它对动物生长和肌肉发育至关重要。例如，在猪饲料中添加啤酒酵母可以为猪提供高质量的蛋白质来源，有助于肌肉生长和体重增加。

Rich in B vitamins: It is a good source of various B vitamins, such as vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B6, and pantothenic acid. These vitamins play a crucial role in the metabolism of animals. For example, vitamin B1 is involved in carbohydrate metabolism, ensuring that animals have sufficient energy supply; Vitamin B2 is important for maintaining the health of animal skin, hair, and normal eye function. Adding beer yeast to poultry feed can help improve the quality of feathers and eggs in poultry.富含B族维生素：它是多种B族维生素的良好来源，如维生素B1（硫胺素）、维生素B2（核黄素）、维生素B6和泛酸。这些维生素在动物的新陈代谢中起着至关重要的作用。例如，维生素B1参与碳水化合物代谢，保证动物有充足的能量供应；维生素B2对维持动物皮肤、毛发和正常眼睛功能的健康很重要。在家禽饲料中添加啤酒酵母有助于提高家禽的羽毛和蛋的质量。

Rich in minerals: Beer yeast contains minerals such as calcium, phosphorus, potassium, magnesium, iron, and zinc. Calcium and phosphorus are key elements for animal bone development. Adding beer yeast to the feed of young animals can provide sufficient mineral foundation for bone growth and prevent bone diseases. Iron also plays an important role in preventing animal anemia, as it participates in the synthesis of hemoglobin and ensures the normal oxygen carrying function of animal blood.富含矿物质：啤酒酵母含有钙、磷、钾、镁、铁和锌等矿物质。钙和磷是动物骨骼发育的关键元素。在幼畜饲料中添加啤酒酵母，可为幼畜骨骼生长提供充足的矿物质基础，预防骨病。铁在预防动物贫血中也起着重要作用，因为它参与血红蛋白的合成，保证动物血液正常的携氧功能。

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

Regulating gut microbiota balance: Beer yeast contains abundant prebiotic components such as mannan. These prebiotics cannot be digested by animals themselves, but can serve as a food source for beneficial gut microbiota such as bifidobacteria and lactobacilli. Beneficial bacteria such as bifidobacteria and lactobacilli proliferate extensively in the intestine, which can inhibit the growth of harmful bacteria such as Escherichia coli and Salmonella, thereby improving the intestinal microbiota environment. For example, adding beer yeast to aquatic animal feed can reduce intestinal diseases caused by harmful bacteria and improve the immunity of aquatic animals.调节肠道菌群平衡：啤酒酵母含有丰富的益生元成分，如甘露聚糖。这些益生元不能被动物自身消化，但可以作为有益肠道微生物群（如双歧杆菌和乳酸杆菌）的食物来源。双歧杆菌、乳酸菌等有益菌在肠道内大量繁殖，可抑制大肠杆菌、沙门氏菌等有害菌的生长，从而改善肠道菌群环境。例如，在水生动物饲料中添加啤酒酵母，可以减少有害细菌引起的肠道疾病，提高水生动物的免疫力。

Enhancing intestinal barrier function: Beer yeast can stimulate the growth and repair of intestinal mucosal cells, thereby enhancing the physical barrier of the intestine. The integrity of the intestinal mucosa can effectively prevent harmful substances (such as toxins and pathogens) from entering the animal's body. At the same time, it can also promote the secretion of immune substances such as immunoglobulin in the intestine, strengthen the immune barrier function of the intestine, and enhance the animal's resistance to diseases.增强肠道屏障功能：啤酒酵母可以刺激肠道粘膜细胞的生长和修复，从而增强肠道的物理屏障。肠道黏膜的完整性可以有效地防止有害物质（如毒素和病原体）进入动物体内。同时还能促进肠道内免疫球蛋白等免疫物质的分泌，增强肠道的免疫屏障功能，增强动物对疾病的抵抗力。

3、 Enhance animal immunity3、增强动物免疫力

Enhancing non-specific immunity: β - glucan in the cell wall of beer yeast is an effective immune enhancer. It can activate the activity of immune cells such as macrophages and natural killer cells in animals. Macrophages can engulf and eliminate foreign pathogens, while natural killer cells can recognize and kill tumor cells and virus-infected cells. For example, adding beer yeast to ruminant animal feed can enhance their resistance to various diseases and reduce the inflammatory response during disease occurrence.

Regulating specific immunity: Beer yeast can regulate the humoral and cellular immunity of animals. It can promote the production of antibodies and enhance the animal's immune response to specific pathogens. At the same time, by regulating the function of immune cells such as T lymphocytes, the balance of immune response is optimized to avoid excessive immunity or immune suppression.

4、 Improve feed palatability and utilization rate

Improving feed palatability: Beer yeast has a unique flavor that can enhance the aroma and flavor of feed, increasing animal feed intake. For some picky eaters or in situations where the quality of feed ingredients is poor, adding beer yeast can make the feed more attractive. For example, adding beer yeast to pet feed will make pets more willing to consume it, ensuring that they receive sufficient nutrition.

Improve feed digestibility: Beer yeast itself contains various enzymes, such as protease, amylase, etc. These enzymes can help animals better digest nutrients such as protein and carbohydrates in their feed. In addition, beer yeast can improve the intestinal health of animals, promote the fermentation of intestinal microbiota, and also help improve the overall digestion and absorption efficiency of feed, reducing feed waste.
