“…In the field of animal nutrition, the development of new potential prebiotics in animal husbandry industries is of current interest. Recently, high-throughput sequencing of 16S rRNA gene amplicons has been used to investigate potential beneficial effects of various feed additives (e.g., xylo-oligosaccharides and yeast cultures) on the gut microbial communities of farmed animals (Liu et al 2018; Pourabedin et al 2015). However, relatively few studies focused on the effects of liquor lees on the composition and function of livestock gut microbiota.…”

“…For example, the probiotics Lactobacillus ( Lactobacillus reuteri avibro ) and Bacillus ( Bacillus subtilis and Bacillus licheniformis ) exhibited the ability to increase nutrient digestibility and animal performance, and they reduced the abundance of pathogens ( Salmonella and Escherichia coli ) (Ahmed et al 2014). In pigs, some prebiotic products, such as xylo-oligosaccharides (XOS), β-mannanase, mannan-oligosaccharides, and yeast cultures have been used to modify gut microbiota composition, improve host immune response, stimulate the growth of more beneficial bacteria, and inhibit the colonization or abundance of pathogens by producing antimicrobial substances in humans and livestock (Barros et al 2015; De Maesschalck et al 2015; Liu et al 2018; Rastall and Gibson 2015). For instance, in broiler chicken, XOS feed additives modulate the gut microbiota and increase the abundance of the potential beneficial bacteria Lactobacillus and Bifidobacterium (Pourabedin et al 2015).…”

Gut microbiota positively contribute to livestock nutrition and metabolism. The manipulation of these microbes may improve animal health. Some feed additives improve livestock health and metabolism by regulating gut microbiota composition and activity. We fed hybrid pigs diets supplemented with 0% (control), 5% (treat 1), 10% (treat 2), or 15% (treat 3) fermented Mao-tai lees (FML) for 90 days. Short-chain fatty acids (SCFAs), bioamines, and microbial communities found in colonic contents were analyzed to investigate microbiota composition and metabolic profiles. Concentrations of straight-chain fatty acids (e.g., acetate, propionate, and butyrate) and tyramine increased with FML supplementation content. Contrary to the minor effects of 5% and 10% FML on gut microbiota, 15% FML influenced beta diversity (Jaccard or Bray–Curtis dissimilarity) but not alpha diversity (number of operational taxonomic units and Shannon diversity) of pig gut microbial communities compared to the control group. Notably, 15% FML animals were characterized by a higher abundance of potentially beneficial bacteria ( Lactobacillus and Akkermansia ) but lower abundances of potential pathogens ( Escherichia ). Numerous genes associated with metabolism (e.g., starch, sucrose, and sulfur-compounds metabolism) showed a higher relative abundance in the 15% FML than in the control group. Additionally, most Phascolarctobacterium , Treponema , Prevotella , and Faecalibacterium bacterial markers in the 15% FML group were positively correlated with straight-chain fatty acid concentrations, suggesting that these bacteria are likely associated with SCFA production. Taken together, our findings demonstrate the beneficial effects of 15% FML on fermentation of undigested compounds and gut microbiota composition in the colon. Thus, 15% FML supplementation in pig feed may possibly represent a way to optimize pig colon health for livestock farming.

“…For aquatic animals, numerous diseases are linked with the dysbiosis of host intestine microbiota ( Li et al, 2017 ; Dai et al, 2020 ; Huang et al, 2020 ). Extensive studies have shown that the intestine microbiota of aquatic animals is strongly affected by diet composition, trophic level, and developmental stage ( Rungrassamee et al, 2013 ; Yan et al, 2016 ; Xiong et al, 2017 ; Liu et al, 2018 ; Walburn et al, 2019 ). These studies have primarily focused on assessing how the intestine microbiota of aquatic animals is affected by biotic factors but ignored abiotic factors.…”

Intestine microbiota is tightly associated with host health status. Increasing studies have focused on assessing how host intestine microbiota is affected by biotic factors but ignored abiotic factors. Here, we aimed to understand the effects of salinity on shrimp intestine microbiota, by comparing the differences of intestine bacterial signatures of shrimp under low-salinity (LS) and high-salinity (HS) culture conditions. Our results found that intestine core bacterial taxa of shrimp under LS and HS culture conditions were different and that under HS contained more opportunistic pathogen species. Notably, compared with LS culture conditions, opportunistic pathogens (e.g., Vibrio species) were enriched in shrimp intestine under HS. Network analysis revealed that shrimp under HS culture conditions exhibited less connected and lower competitive intestine bacterial interspecies interactions compared with LS. In addition, under HS culture conditions, several opportunistic pathogens were identified as keystone species of intestine bacterial network in shrimp. Furthermore, the ecological drift process played a more important role in the intestine bacterial assembly of shrimp under HS culture conditions than that under LS. These above traits regarding the intestine microbiota of shrimp under HS culture conditions might lead to host at a higher risk of disease. Collectively, this work aids our understanding of the effects of salinity on shrimp intestine microbiota and helps for shrimp culture.

“…These may act on the gastrointestinal tract (GIT) directly to maintain the balance of the microorganism and promote development of the GIT. For example, YC can signi cantly affect community structure and composition of gut microbiota of grass carp, increasing the abundance of bene cial bacteria [11] . Addition of YC in the diet resulted in an increase in bene cial bacteria, making greater compensatory weight gains in weanling pigs [12] .…”

BackgroundOne of the most extensively applied animal feed additives is yeast culture (YC), which can increase production efficiency by altering gastrointestinal tract (GIT) microbiota. However, its use is still limited in waterfowl. Geese are the ideal model to study the interaction between dietary and GIT, due to their adaptation to consume different roughage sources. Therefore, the effect of YC supplementation at different concentrations (0%, 0.5%,1.0%,2.0% and 4.0%) on the GIT microbiota of geese was investigated in the present study. ResultsThree hundred Sichuan white geese with healthy and similar body weight (BW: 95.57 ± 2.42 g) were randomly divided into five groups: i) basal diet (control), ii) basal diet+0.5%YC (treat1), iii) basal diet+1.0% YC (treat2), iv) basal diet+2.0% YC (treat3), and v) basal diet+4.0% YC (treat4). After 10 weeks, slaughter and collected the cecum contents, then analysis GIT microbiota by high-throughput sequencing. The results showed that YC supplementation did not significantly affect α-diversity (P ＞0.05). Principal coordinates analysis showed an obvious separation between control and treat4. The dominant phyla were Firmicutes and Bacteroidetes whereas the predominant genera were Alistipes and Desulfovibrionaceae. The relative abundance of Firmicutes significantly increased in the treat1 group, whereas that of Bacteroidetes significantly decreased in the treat4 group. Dietary YC increased the proportion of beneficial bacteria, such as Parabacteroides, Enterococcus, Streptococcus and Pseudomonas, particularly in group treat2. Furthermore, treat3 significantly improved the body weight and feed utilization of geese.ConclusionCollectively, these findings demonstrate that dietary YC supplementation tends to increase species diversity and richness of GIT microbiota in geese. This increases the proportion of beneficial bacteria which improves amino acid and carbohydrate metabolism. Moreover, YC increases the relative abundance of Firmicutes that promote energy utilization and nutrition absorption, thereby improving the growth performance of geese. This dietary strategy based on feed additives is an effective method to maintain the health of the geese GIT and to improve growth efficiency.
