Introduction One of the biggest and fastest-growing industries in the world is chicken, and the abundance of pathogenic microorganisms makes practical management difficult and results in large financial losses (Anwar et al., 2017). Yeast cell wall (YCW)-glucans are used in chicken’s feed to overcome the aforementioned constraints. The food containing β-glucans can improve growth performance (Cho et al., 2013), promote macrophage phagocytosis following bacterial infection (Chen et al., 2008), and lessen the severity of enteric pathogen infection (Huff et al., 2006; Shao et al., 2013). Even at low doses, consumers generally accept that the use of yeast-glucans is more beneficial than

Over the past four decades, shrimp aquaculture has developed into a significant sector that employs millions worldwide, particularly in nations with extensive coastlines. However, the shrimp industry is still growing, and the emergence of illnesses has jeopardized shrimp aquaculture’s long-term viability. Similarly, the arbitrary use of antibiotics to ward off these illnesses has resulted in the development of some resistant infections in aquaculture. The idea of functional aqua feeds is a new paradigm that has gained traction in the aquaculture business. It generates diets that not only contribute to balanced nutrition but also contain some chemicals that significantly enhance the

The animal protein industry has exponentially grown, and intensive production practices cause unavoidable stress to the animals as a result of confinement, transport and handling. Stress generates a physiological condition characterized by suppressed immunity, and consequently, higher disease susceptibility. Yeast Beta Glucan in Aquaculture In aquaculture, in particular, fish are not easily observed by the stock person, and disease outbreaks are often overlooked. Therefore, novel ways to boost the immune response of fish are needed. One natural option that is highly effective is the use of beta glucan because they are considered modifiers of biological response due to their immunomodulatory

Introduction Yeast beta-glucan and Yeast Cell Wall (YCW) are two additives from yeast that could provide Polysaccharides in Feed. They are yeast derivatives to improve animal performance, and there are different confusing concepts between them.  In this article, beta-glucans and YCW will be put together to discuss their relation, function, and usage in the field of animal nutrition. Brief on Yeast Cell Wall  YCW is often called the MOS product; it is the natural source of mannan-oligosaccharides (MOS) and Yeast 1,3/1,6-D-beta glucan. YCW contains 20%-35% Mannan, 20%-35% Glucan, 2%, and less than 35% protein.  In the feed industry, Yeast cell
