What are the roles played by Bacillus licheniformis in animal feed?

地衣芽孢杆菌在动物饲料中的作用是什么?Summarized into three aspects:归纳为三个方面:归纳为三个方面:

1、 In terms of physiological function regulation, Bacillus licheniformis can regulate and maintain the ecological balance of intestinal microorganisms, quickly colonize in the intestine, consume oxygen quickly, and form an anaerobic environment, which is conducive to the physiological activities of other probiotics in the intestine, store in the gastrointestinal function, help digestion and absorption in the intestine, and promote the growth and development of farmed animals.1、在生理功能调节方面，地衣芽孢杆菌可以调节和维持肠道微生物的生态平衡，在肠道内迅速定植，迅速消耗氧气，形成厌氧环境，有利于肠道内其他益生菌的生理活动，储存在胃肠功能中，帮助肠道内的消化吸收，促进养殖动物的生长发育。

2、 Health protection effect: 2、保健作用:

      Bacillus licheniformis can secrete antibacterial substances, reduce the occurrence of gastroenteritis, prevent and treat diarrhea, and has a significant therapeutic effect on bacteria. It can significantly inhibit the growth and reproduction of harmful bacteria such as Staphylococcus aureus and Candida albicans, and improve the non-specific immunity of animals.地衣芽孢杆菌能分泌抗菌物质，减少肠胃炎的发生，防治腹泻，对细菌有显著的治疗作用。能明显抑制金黄色葡萄球菌、白色念珠菌等有害细菌的生长繁殖，提高动物的非特异性免疫力。地衣芽孢杆菌能分泌抗菌物质，减少肠胃炎的发生，防治腹泻，对细菌有显著的治疗作用。能明显抑制金黄色葡萄球菌、白色念珠菌等有害细菌的生长繁殖，提高动物的非特异性免疫力。

3、 Nutritional effects: 3、营养作用:

       Bacillus licheniformis can secrete various enzymes, such as gelatinase, amylase, lipase, cellulase, etc., which not only make up for the problem of insufficient endogenous enzymes in animals, but also produce some small molecule proteins and organic acids that are more easily digested and absorbed by animals, improving feed utilization efficiency, low production costs, and higher benefits. Bacillus licheniformis also has a special function of decomposing feathers, which contain a large amount of protein that is difficult to digest and absorb. Bacillus licheniformis can degrade the macromolecular protein in it, making it available as feed for breeding animals and waste utilization.地衣芽孢杆菌能分泌多种酶，如明胶酶、淀粉酶、脂肪酶、纤维素酶等，不仅弥补了动物内源酶不足的问题，而且还能产生一些更容易被动物消化吸收的小分子蛋白质和有机酸，提高了饲料利用效率，降低了生产成本，提高了效益。地衣芽孢杆菌还具有分解羽毛的特殊功能，羽毛中含有大量难以消化吸收的蛋白质。地衣芽孢杆菌可降解其中的大分子蛋白质，使其可作为饲养动物的饲料和废物利用。地衣芽孢杆菌能分泌多种酶，如明胶酶、淀粉酶、脂肪酶、纤维素酶等，不仅弥补了动物内源酶不足的问题，而且还能产生一些更容易被动物消化吸收的小分子蛋白质和有机酸，提高了饲料利用效率，降低了生产成本，提高了效益。地衣芽孢杆菌还具有分解羽毛的特殊功能，羽毛中含有大量难以消化吸收的蛋白质。地衣芽孢杆菌可降解其中的大分子蛋白质，使其可作为饲养动物的饲料和废物利用。

      A study explored the effects of Bacillus licheniformis on laying hens and their gut microbiota. Through experiments on 400 laying hens, it was found that adding Bacillus licheniformis to the diet of laying hens can promote beneficial bacterial proliferation, inhibit the number of harmful bacteria, and improve gut microbiota. It can also increase the villus height and V/C ratio of the duodenum and jejunum of laying hens, reduce the thickness of the intestinal mucosa, and improve the morphological structure of the intestine. 本研究探讨地衣芽孢杆菌对蛋鸡及其肠道菌群的影响。通过对400只蛋鸡的试验发现，在蛋鸡饲粮中添加地衣芽孢杆菌可促进有益菌增殖，抑制有害菌数量，改善肠道菌群。还能提高蛋鸡十二指肠和空肠的绒毛高度和V/C比，降低肠黏膜厚度，改善肠道形态结构。

      A large number of experiments have shown that Bacillus licheniformis has a significant effect on regulating gastrointestinal diseases or intestinal function caused by bacteria in animals, and is suitable for various breeding animals such as chickens, ducks, geese, pigs, cows, and sheep.大量实验表明，地衣芽孢杆菌对调节动物由细菌引起的胃肠道疾病或肠道功能有显著作用，适用于鸡、鸭、鹅、猪、牛、羊等多种养殖动物。大量实验表明，地衣芽孢杆菌对调节动物由细菌引起的胃肠道疾病或肠道功能有显著作用，适用于鸡、鸭、鹅、猪、牛、羊等多种养殖动物。
