Background:The dietary supplementation of yeast cell wall extracts(YCW)has been found to reduce pathogenic bacteria load,promote immunoglobulin production,prevent diseases by pro-inflammatory responses,and alter gut microbiota *** study evaluated growth and slaughter results,health,gut morphology,immune status and gut transcriptome of 576 male chickens fed two diets,i.e.C(control)or Y(with 250–500 g/t of YCW fractions according to the growth period).At 21 and 42 d the jejunum of 12 chickens per diet were sampled and stained with hematoxylin/eosin for morphometric evaluation,with Alcian-PAS for goblet cells,and antibodies against CD3+intraepithelial T-cells and CD45+intraepithelial *** jejunum sampled at 42 d were also used for wholetranscriptome ***:Dietary YCW supplementation did not affect final live weight,whereas it decreased feed intake(114 to 111 g/d;P≤0.10)and improved feed conversion(1.74 to 1.70;P≤0.01).Regarding the gut,YCW supplementation tended to increase villi height(P=0.07);it also increased the number of goblet cells and reduced the density of CD45+cells compared to diet C(Pme,four genes were expressed more in broilers fed diet Y compared to diet C,*** P450,family 2,subfamily C,polypeptide 23b(CYP2C23B),tetratricopeptide repeat domain 9(TTC9),basic helix-loop-helix family member e41(BHLHE41),and the metalloreductase *** one gene set(HES_PATHWAY)was significantly enriched among the transcripts more expressed in broilers fed diet ***,a total of 41 gene sets were significantly over-represented among genes up-regulated in control ***,several enriched gene sets are implicated in immune functions and related to NF-κB signaling,apoptosis,and interferon ***:The dietary YCW supplementation improved broiler growth performance,increased gut glycoconjugate secretion and reduced the inflammatory status together with differences in the gut tran
