“…Quantification of selected species of bacteria belonging to pathogenic or non-pathogenic group showed that non-pathogenic bacteria (Bifidobacteria and Enterococci) greatly increased along with decrease in pathogenic ones (E. coli, Clostridia, Enterobacteria and Campylobacter). This is a strong prebiotic-like effect as such reported with usage of known prebiotics (Guo et al 2004;Abudabos et al 2015). To the best of our knowledge, this is the first study reporting such effect for dietary TRP.…”

Stimulation of serotonergic activity by tryptophan (TRP) supplementation is known to influence behavioural and physiological processes. One hundred and twenty male broiler chicks were assigned in groups of 5-24 battery cage and fed experimental diets with 0.22, 0.42 and 0.62% of digestible TRP during 21-42 d. On 42 d, birds were challenged with 2 h of transportation stress and samples were collected before or after the transportation. The results revealed that TRP increased feed intake, but had no significant effect on growth performance. Regardless of transportation, heat shock protein 70 (HSP70) and corticosterone (CORT) decreased and serotonin (5-HT) elevated by increasing TRP level in diet. Breast muscle pH and colour were not affected by elevation in dietary TRP, but drip loss decreased and shear force increased. Quantification of gut microflora showed that supplementation of TRP increased Enterococci, and Bifidobacteria populations, while E. coli, Clostridia, Campylobacter and Enterobacteria populations decreased. The effect of diet on Lactobacilli population was not significant. In conclusion, feeding broilers with higher levels of TRP improves their welfare condition both before and after transportation stress, as measured by lower serum CORT and HSP70 and higher 5-HT. Increasing dietary TRP level may shift the balance of pathogenic/non-pathogenic bacteria in gut to a favourable state.

“…It could be due to the ine cacy of PrimaLac® probiotic to colonise in the intestines. This result was in contrast with the previous studies, where probiotic supplementation was found to increase the level of probiotic bacteria in chicken intestines [36,49,54]. It also need to be highlighted that in the current study, PrimaLac® probiotic microbes such as Enterococcus faecium and Aspergillus oryzae were not quanti ed, where their populations might be elevated in probiotic supplemented groups.…”

“…In the current study, chickens from probiotic supplemented groups (P, 1 P and 2 P) had signi cantly lower population of C. perfringens compared to the control at 21 d caeca. This result was consistent with previous studies, in which C. perfringens population was signi cantly lower in chickens supplemented with probiotic [49]. This was due to the protective roles of probiotic in reducing pathogens based on the reported mode of actions of competitive exclusion [48,42] and antagonistic activity [44,43,32,60].…”

Background Probiotics are the most recognised alternative to antibiotic growth promoters (AGPs) for poultry production. They adhere to the intestinal epithelial cells to exert their beneficial effects on the host. However, this is often restricted by indigenous gut microbes that compete for adhesion sites and nutrients. Therefore, phage application has been proposed to reduce the competition of probiotics with gut microbiota. The main objective of this study was to investigate the effects of phages on the gut microbiota and their impact on probiotic efficacy in chickens. Results Four best Escherichia coli lytic phages were selected and characterised. The in vivo trial was conducted to investigate the effects of dietary treatments of phage cocktail at 0.1% (1ɸ) and 0.2% (2ɸ), 0.1% PrimaLac ® probiotic (P) and their combinations (1ɸP, 2ɸP) on growth performance and gut microbiota of chickens. The results from the in vivo trial showed that chickens in the 1ɸP group had significantly (P < 0.05) better body weight (BW), body weight gain (BWG), and feed conversion ratio (FCR), lower serum triglycerides and higher ileal villus height than the control. Chickens in the 1ɸP group also had higher (P < 0.05) ileal villus height, and lower crypt depth than those in the probiotic group. The gut microbiota profiles revealed that 1ɸP supplementation significantly (P < 0.05) reduced E. coli population, increased (P < 0.001) short chain fatty acids (SCFAs) producers, and improved (P < 0.001) gene expressions that are related to carbohydrate and amino acid metabolisms, and nutrient uptake. Conclusions The results from this study showed that 1ɸP treatment could modulate the gut microbiota and enhance growth performance in chickens. This finding could be considered as a potential alternative to AGPs for poultry.

Simple Summary: Antibiotics have been commonly used worldwide as growth promoters and for prophylactic treatment of diarrhea in weaning piglets. However, The European Union has banned the use of antibiotic growth promoters in animal production. Therefore, finding alternative solutions for preventing diarrhea in weaning piglets is urgent. Modulation of gut microbiota composition by probiotics has a beneficial effect on animal health. In this study, we assessed the effects of Bacillus licheniformis-fermented products on diarrhea incidence and the fecal microbiome composition in weaning piglets. Results showed that B. licheniformis-fermented products could improve diarrhea incidence and the fecal microbiota community in weaning piglets. These findings indicate that B. licheniformis-fermented products have the potential for development as feed additives and use as possible substitutes for antibiotics to prevent postweaning diarrhea in the pig industry.Abstract: Prophylactic use of antibiotics in-feed has been effective in decreasing the incidence of diarrhea in weaning piglets. However, the overuse of antibiotics as prophylactic or therapeutic agents in animal feed leads to the evolution of drug-resistant bacteria and antibiotic residues in pigs. This study investigated the effects of Bacillus licheniformis-fermented products on diarrhea incidence and the fecal microbial community in weaning piglets. A total of 120 crossbred piglets with an average initial body weight of 9.87 ± 1.43 kg were randomly allotted to four dietary treatments consisting of three replicate stalls with 10 piglets in each. The dietary treatments comprised a basal diet as control, control plus 1 g/kg or 4.5 g/kg of B. licheniformis-fermented products, and control plus 30 mg/kg antibiotics (bacitracin methylene disalicylate). Results showed that 4.5 g/kg of B. licheniformis-fermented product supplementation significantly reduced diarrhea incidence in weaning piglets. Principal coordinate analysis and a heatmap of species abundance indicated distinct clusters between the groups treated with antibiotics and B. licheniformis-fermented products. The bacterial richness and evenness in the feces decreased in weaning piglets fed 1 g/kg of B. licheniformis-fermented products and antibiotics. The abundance of the genera [Ruminococcus] gauvreauii group, Ruminococcaceae UCG-005, and Ruminococcaceae UCG-008 in the feces decreased in weaning piglets fed B. licheniformis-fermented products or antibiotics. The average abundance of the genus Prevotella 9 in the feces was positively correlated with the concentration Animals 2019, 9, 1145 2 of 15 of B. licheniformis-fermented products and negatively correlated with the diarrhea incidence in weaning piglets. Furthermore, the average abundance of the genus Prevotella 9 in the feces was positively correlated with the growth performance of weaning piglets. These results demonstrate that B. licheniformis-fermented products can improve diarrhea incidence and fecal microflora composition in weaning piglets.
