- W2901835110 abstract "The aim of this project was to evaluate the effects of probiotics, prebiotics and synbiotics on the gut ecosystem, immune function and growth parameters of broiler. The first study screened naturally occurring Campylobacter levels in four local sites and revealed the NTU broiler research unit and the NTU animal unit laying hens were Campylobacter free, but a small holding with laying hens was positive and the commercial broiler farm was negative until thinning, after which it was positive. The second study investigated possible delivery routes of a novel strain of Lactobacillus johnsonii (FI9785) into broiler chicken gut and concluded feed was the optimum method for delivery. A third study compared the effect L. Johnsonii FI9785 supplied via feed to control and showed no significant difference in the CFU of caecal Campylobacter, no significant (p≤0.05) effects on growth performance and serum uric acid concentration over 4 weeks. However, mucin layer thickness in the jejunum was significantly (P≤0.05) increased. Concentration of IgA in the serum blood of probiotic treated birds was also increased but IgM and IgG were not significantly altered. Study 4 involved isolation and in vitro screening of candidate probiotic isolates of lactic acid bacteria and a prebiotic from Jerusalem artichoke plant (JA). All tests confirmed the isolates had the characteristics of lactic acid bacteria and have an inhibition activity toward Campylobacter. All isolates belonged to the genus of Lactobacillus and all retained viability during freezing and drying and the poultry gastrointestinal environment, indicating all were potential probiotic agents. Assessment of JA inulin levels indicated the plant to be a potentially good prebiotic source with these isolates. Study 5 investigated in vivo effects of the Lactobacillus isolates (probiotic), JA powder (prebiotic), synbiotic (mix of pre and probiotic). Caecal content were negative for Campylobacter throughout but at day 7, abundance of Firmicutes phyla were higher (p≤0.05) than control for all of supplements treatments and abundance of Faecalibacterium genus numerically increased in all treatments but significantly (p≤0.05) only in 5% prebiotic and probiotic supplemented diets. At day 42, abundance of genus of Erysipelotrichaceae decreased in all treatments. Assessment of growth performance showed JA had no effects but probiotic and synbiotic supplementation caused a degradation in the body weight and increased feed intake. Supplements downregulated the cytokine expression IFNγ,IL-10 and IL-6 in the ileum tissue but showed no effect in the bursa tissue." @default.
