In a context moving towards antibiotic-free livestock production, research in feed additives has largely increased to evaluate different products and their effects on animal health and immune response, in addition to animal productivity [Xue at al., 2017]. Among the different products, prebiotics such as yeast cell wall (YCW)<\/span><\/strong> extracts have been widely used; they comprise mannanoligosaccharides (MOS), mannan-proteins, \u03b2 (1,3)- glucans, \u03b2 (1,6)-glucans, chitin, and glycophospholipid surface proteins associated with the plasma membrane [Guang-Da et al., 2017].<\/p>\n\n\n\n
Background<\/strong><\/strong><\/p>\n\n\n\n
The different yeast fractions can modulate animal gut health by different mechanisms. Dietary supplementation with MOS has been found to improve gut morphology<\/span><\/strong> in terms of longer villi, shorter crypts, and a higher number of goblet cells [Baurhoo et al., 2007]. In infected chicks (Salmonella typhimurium and Clostridium perfringens), MOS positively affected immune and metabolic pathways in the gut and reduced its colonization<\/span><\/strong> [Caly et al., 2015; Faber et al., 2012; Hashim et al., 2018]. <\/p>\n\n\n\n
