我国农业部1126号公告"饲料添加剂品种目录(2008)"规定了16种饲用益生菌,益生菌的作用机理主要是通过改变肠道菌群实现的,饲用益生菌菌株的活性会在工厂化大生产中降低,可以借鉴丹麦的经验,现场制作益生菌发酵液,得到活性较高的益生菌。 相似文献

饲用益生菌制剂是一种通过改善肠道菌群平衡而对动物施加有利影响的活的微生物饲料添加剂．其主要通过调节动物体内消化道pH值和肠道菌群平衡．以及增强非特异性免疫功能来预防疾病,促进动物生长。益生菌制剂的功效与益生菌制剂的种类、活菌数、使用剂量、动物类型、使用条件等密切相关,因此必须掌握饲用益生菌的筛选与使用技术。 相似文献

Probiotics--possibilities and limitations of their application in food, animal feed, and in pharmaceutical preparations for men and animals] 总被引：2，自引：0，他引：2

Probiotics are cultures of special microorganisms, which have been used as feed additives since the seventies of the past century and already since the twenties in food specimen and in pharmaceuticals. The definition of "Probioticum" was formulated in 1974 simultaneously with the use of living cultures in feed for various animals in order to substitute the application of nutritive antibiotics or chemotherapeutics. In the meantime probiotics are applied not only as feed supplements or pharmaceuticals but increasingly in suitable food specimens such as dairy products, fruit juices, chocolates, and even meat products. Of course, heating of such products prior to consumption or application must be ruled out. The selection of a suitable strain of a microorganism can be regarded as the primary requirement for the use as a probiotic. These cultures must be able to pass the stomach-duodenum barrier in a viable state and to multiply at the site of destination in the intestine. Additionally, they must be capable of producing antagonistic metabolites against a dominating saprophytic microflora resulting in a competitive growth. These abilities are common among lactic acid bacteria, e.g. lactobacilli and bifidobacteria. Yet, intended autochthonous species do not possess very good technological features for the enrichment in food specimens, because their viability will decrease rapidly under unfavourable conditions as it is the case with mineral supplements in feed or with low acidity in fermented dairy products. Therefore, some other microorganisms like spore-forming species or yeast cultures were introduced as probiotic components. These possess some similar features which render them suitable for probiotic use. But their physiological and ecological traits do not qualify them as probiotics of first choice. The special efficacy of probiotics must be strictly verified in animal nutrition due to restrictive EC-regulations, in pharmacy due to legal restraints, and in food applications in accordance with food law regulations. Safety aspects are considered very restrictively in feed applications, in the food and pharmaceutical sector they should be in accordance with the intended purpose of "fulfilling health claims". In the presented review the different requirements for the application of probiotics in animal nutrition, in food, and in pharmaceuticals will be provided. The special effect of competitive exclusion of pathogenetic and toxinogenic microorganisms in fowl performance are mentioned and even the application of probiotics as marine aquacultures of fish and Crustaceae will be included. Furthermore, the safety aspects resulting from the tremendous amount of industrially produced cultures which are distributed into the environment will be discussed. In conclusion it may be pointed out that probiotics may serve to partially replace the presently reduced or even prohibited application of nutritive antibiotics or chemotherapeutics in animal nutrition and in fulfillment of health claims in man and animals. Economic and environmental aspects will reduce the overall application of probiotics world-wide. Restrictions of use and controls of efficacy and safety are essential and must be implemented periodically. 相似文献

我国啤酒生产每年会产生大量的副产物麦糟和废酵母,而屠宰行业也会产生大量的禽畜血液副产物,两者具有很高的营养价值,适合作为发酵饲料的原料加以利用。以麦糟为主料,加入血粉辅料,混合接种不同益生菌,通过测定发酵产物蛋白质含量、糖含量及总酸含量等指标,分别评价不同主辅料配料比、发酵时间、酵母菌及乳酸菌接种方式及接种量等因素对混合发酵饲料品质的影响,筛选生产发酵蛋白质饲料的最佳条件。结果表明：在血粉辅料添加量为15.00%、发酵温度为30 ℃、接种酵母菌单一菌种且接种量为2.00%、发酵时间为5 d的条件下,获得的发酵产物品质较好,蛋白质含量达到50.36%,与初始样品的蛋白质含量相比,提升幅度达到75.53%;利用酵母菌及乳酸菌混合发酵时,先接入1.00%乳酸菌发酵2 d后,再接入1.00%酵母菌继续发酵至7 d时,产物的蛋白质含量达到59.27%,与初始样品的蛋白质含量相比,提高幅度达到106.59%。利用上述2种发酵方式得到的产品可作为良好的蛋白质饲料。 相似文献

The feed antibiotics are long added into the feed as growth promoters,resulting in a series of problems,such as drug residues in livestock products,drug-resistant strains emergence and environmental pollution.Probiotics fermented feed can reduce the anti-nutritional factors in raw materials, produces beneficial metabolites, soluble peptides and other small molecules,that will enhance the nutritional level of feed, play a role in promoting growth and improving immune function.The present studies have showed that probiotics fermented feed will be one of the potential solutions. Therefore, this paper will be focused on the effects of probiotic fermented feed on piglet growth and immunity, which will provide the theoretical base for further study in this field. 相似文献

饲用抗生素作为促生长剂在饲料中被长期添加,造成了畜禽产品的药物残留、耐药菌株的出现和环境污染等问题。益生菌发酵饲料是改变当前养殖状况极具潜力的解决方案之一。益生菌发酵饲料能减少原料中抗营养因子,产生有益代谢产物和可溶性多肽等小分子物质,从而提高饲料营养水平,起到促生长和提高免疫功能的作用。作者就益生菌发酵饲料对仔猪生长和免疫功能方面的影响进行综述,以期为进一步研究益生菌发酵饲料对仔猪生长和免疫的影响提供一定理论依据。 相似文献
