Microbial biofilm-related infections present a significant global health challenge,posing a major threat to public health systems[1].Biofilms,complex structures formed by the aggregation of microorganisms,are commonly found on medical devices,human tissue surfaces,and in natural environments[2].These biofilms exhibit high levels of antibiotic resistance and survival stability,rendering traditional antibiotic treatments ineffective in eradicating infections[3].

The current study aimed to compare the effects of increasing concentrations of dietary threonine(Thr),tryptophan(Trp),and glycine(Gly)on growth performance,stress biomarkers,and intestinal function in broiler chickens under multiple stress *** hundred sixty broiler chickens at 21 d old were randomly allotted to 5 treatments with 8 *** in a positive control(PC)treatment were raised under low stock density(16.9 birds/m2 per cage)with recommended environmental conditions,whereas birds in 4 treatments were subjected to multiple stress conditions:a cyclic heat stress of 30±0.3°C for 10 h and 23±0.2°C for 14 h per day with high stock density(25.3 birds/m2 per cage).A basal diet was assigned to both PC and negative control(NC)*** additional diets were individually formulated to contain double concentrations of digestible Thr,Trp,or Gly+Ser compared with their concentrations in the basal *** experiment lasted for 14 *** showed that NC treatment had less growth performance(P<0.001),jejunal goblet cell counts(P=0.018),and trans-epithelial electrical resistance(TEER;P<0.001),but greater(P=0.026)feather corticosterone(CORT)concentrations than PC *** treatment showed the least(P<0.001)feed conversion ratio(FCR)among treatments under multiple stress ***,Trp,and Gly treatments had less(P=0.026)feather CORT concentrations,but had greater(P<0.001)TEER than NC *** conclusion,increasing concentrations of dietary Thr,Trp,or Gly improve the growth performance and intestinal health in broiler chickens with decreasing stress response under multiple stress conditions.
