Abstract

SUMMARY Poultry is an important source of human protein so research was done to identify methods of improving the feed quality and overcoming the challenge of using this feed type. Poultry feed is commonly contaminated with certain organisms like fungi which produce a group of secondary metabolites called mycotoxins, which affect the quality of the feed. These mycotoxins are highly toxic even in a small concentration like ochratoxin A (OTA), deoxynivalenol, and T-2 toxin causing a wide range of disorders such as hepatic and kidney injury, etc. This review aims to provide an insight into this problem and the use of yeast and its derived products as a method to overcome these mycotoxins. In the literature, yeast is applied to poultry feed as it promotes the growth of broilers when added to the diet and enhances immunity by increasing the antibody titre and macrophages. It increases the size of immunity organs like the thymus gland and the spleen, improves gut immunity, and decreases the proportion of certain microorganisms like E. coli and Salmonella. Lachancea Thermotoleran is an example of a yeast strain that produces volatile organic compounds like 2-phenyl ethanol, which decreases the production of OTA by certain percentages according to the applied conditions. Therefore, the inclusion of yeast was applied as a promising feed additive to overcome mycotoxins in poultry diets because of its many benefits.

酵母及其衍生产品:在家禽饲料中预防霉菌毒素的用途
家禽是人类蛋白质的重要来源,因此进行了研究,以确定提高饲料质量和克服使用这种饲料的挑战的方法。家禽饲料通常会受到真菌等微生物的污染,这些微生物会产生一组称为真菌毒素的次级代谢物,从而影响饲料的质量。这些真菌毒素即使在很小的浓度下也具有很高的毒性,如赭曲霉毒素a (OTA)、脱氧雪腐镰刀菌醇和T-2毒素,可引起广泛的疾病,如肝和肾损伤等。这篇综述的目的是提供一个深入了解这个问题和酵母及其衍生产品的使用作为一种方法来克服这些真菌毒素。在文献中,酵母被应用于家禽饲料中,因为酵母添加到饲料中可以促进肉鸡的生长,并通过增加抗体滴度和巨噬细胞来增强免疫力。它可以增大胸腺和脾脏等免疫器官的大小,提高肠道免疫力,并减少大肠杆菌和沙门氏菌等某些微生物的比例。Lachancea Thermotoleran是一种产生挥发性有机化合物(如2-苯基乙醇)的酵母菌株的例子,它根据应用条件将OTA的产量降低一定百分比。因此,酵母作为一种很有前途的饲料添加剂被应用于克服家禽饲料中的霉菌毒素,因为它有许多好处。

期刊介绍: World''s Poultry Science Journal is the official publication of the World’s Poultry Science Association. The journal provides authoritative reviews in poultry science and an international forum for the exchange and dissemination of information including research, education and industry organisation. Each issue includes poultry industry-related news, regional reports on global developments in poultry, reports from specialist scientific working groups, book reviews, association news and a calendar of forthcoming events. Coverage includes breeding, nutrition, welfare, husbandry, production systems, processing, product development, physiology, egg and meat quality, industry structure, economics and education. The journal is of interest to academics, researchers, students, extension workers and commercial poultry producers.
