Gut microbiota remodeling drived by dietary millet protein prevents the metabolic syndrome
Researchers found that millet bran protein extract prevented metabolic syndrome in high-fat diet mice by remodeling gut microbiota and reducing obesity, chronic inflammation, and insulin resistance. The protective effects were linked to specific gut microbial metabolites influenced by dietary millet protein.
Xylooligosaccharide Supplementation Mitigates Growth Performance Impairment and Intestinal Injuries in Enterohemorrhagic Escherichia coli-Challenged Broilers
Researchers supplemented broiler chickens with xylooligosaccharide (XOS), a prebiotic, and then challenged them with enterohemorrhagic E. coli, finding that XOS improved growth performance and intestinal health compared to unsupplemented EHEC-challenged birds.
Polyethylene microplastics impair chicken growth through gut microbiota-induced hepatic fatty acid metabolism dysfunction
This study showed that polyethylene microplastics, especially those containing chemical additives called phthalates, significantly slowed chicken growth by disrupting liver fat metabolism and gut bacteria. The microplastics altered the balance of intestinal microbes, which in turn affected how the liver processed fats. Since chickens are a major human food source, these findings raise questions about how microplastic contamination in poultry feed could affect both animal welfare and food quality.
Leveraging Lactobacillus plantarum probiotics to mitigate diarrhea and Salmonella infections in broiler chickens
Researchers developed an affordable probiotic formulation using Lactobacillus plantarum bacteria and tested its ability to protect broiler chickens from Salmonella infections. Chickens given the probiotic showed significantly improved weight gain and up to 86 percent reduction in diarrhea caused by Salmonella. The beneficial effects were attributed to the probiotic's ability to support gut lining integrity and shift the microbiome toward healthier bacterial populations.
Cost-Effective Enzyme Optimization and Encapsulation from Bacillus subtilis for Poultry Feed Enrichment
Researchers optimized and encapsulated proteases from Bacillus subtilis to improve enzyme stability and performance under industrial conditions for use in poultry feed enrichment. The study addressed the challenge that microbial enzymes, despite high commercial demand, often perform poorly under extreme temperature and pH conditions encountered in large-scale applications.
The impact of polyethylene microplastics exposure on the, growth performance, reproductive performance, antioxidant capacity, and intestinal microbiota of quails
Researchers fed quails different levels of polyethylene microplastics and found that exposure harmed their growth, reproduction, and gut health. The microplastics reduced antioxidant defenses and disrupted the balance of beneficial bacteria in the birds' intestines. Since poultry is a major food source for people, microplastic contamination in farm animals raises concerns about indirect human exposure through the food chain.
Exploring the Crucial Role of the Gut Microbiome in Advancing Food Processing Technologies
This review explores the role of gut microbiome composition in food processing and technology development, examining how microbial communities influence fermentation, nutrient bioavailability, and food safety, with implications for probiotic and prebiotic product design.
Exposure to known and emerging groundwater contaminants significantly alters poultry microbiome and metabolome
Researchers exposed broiler chickens to low-level mixtures of agricultural chemicals and microplastics via contaminated groundwater and found that gut microbial communities and metabolic pathways were significantly altered — including disrupted energy metabolism and cofactor availability — without observable intestinal damage, revealing a form of subclinical dysbiosis.
The potential influence of food additives and contaminants on the gut microbiota: A comprehensive review
This comprehensive review examines how food additives and contaminants, including pesticides, heavy metals, microplastics, and antibiotics, affect the gut microbiota. Researchers found that these substances can disrupt the balance of gut microbes, leading to inflammation, gastrointestinal injury, and altered production of beneficial short-chain fatty acids. The study emphasizes the need for further research into the mechanisms by which dietary contaminants affect gut health and overall wellbeing.
Combined Effects of Yellow Mealworm (Tenebrio molitor) and Saccharomyces cerevisiae on the Growth Performance, Feed Utilization Intestinal Health, and Blood Biomarkers of Nile Tilapia (Oreochromis niloticus) Fed Fish Meal-Free Diets
Researchers tested yellow mealworm meal as a replacement for fishmeal in Nile tilapia diets, finding that adding the probiotic yeast Saccharomyces cerevisiae improved fish growth, gut health, liver condition, and immune function. This suggests insect-based feeds combined with probiotics can sustainably replace traditional fishmeal in aquaculture.
Emerging applications of postbiotics to sustainable livestock production systems
This review examines the emerging use of postbiotics, which are beneficial compounds produced by probiotic bacteria, as natural feed additives in livestock production. Researchers found that postbiotics show promise for improving animal growth, gut health, and fertility without the risks associated with live probiotic bacteria, such as antibiotic resistance gene transfer. The study suggests postbiotics could be a more stable and safer alternative for promoting sustainable animal production.
Relevance of gut microbiome research in food safety assessment
This review examined how the gut microbiome metabolizes non-nutritious dietary compounds, arguing that gut microbial processing of food contaminants and additives is an underappreciated dimension of food safety assessment.
Co-housing with Tibetan chickens improved the resistance of Arbor Acres chickens to Salmonella enterica serovar Enteritidis infection by altering their gut microbiota composition
Researchers found that housing standard Arbor Acres chickens alongside disease-resistant Tibetan chickens improved the gut microbiome of the standard birds, making them more resistant to Salmonella infection without weakening the Tibetan chickens — suggesting a practical, drug-free strategy for reducing bacterial illness in poultry farming.
Aquaculture Water Quality Improvement by Mixed Bacillus and Its Effects on Microbial Community Structure
This study tested two combinations of beneficial Bacillus bacteria in crucian carp aquaculture tanks, finding they improved water quality by reducing nitrogen and phosphorus compounds and shifted microbial community structure toward more beneficial species.

Modulation of Atlantic salmon (Salmo salar) gut microbiota composition and predicted metabolic capacity by feeding diets with processed black soldier fly (Hermetia illucens) larvae meals and fractions
Researchers fed Atlantic salmon different preparations of black soldier fly larvae — whole, de-fatted, or with exoskeletons removed — and found that full-fat larvae meal most favorably altered the gut bacteria in young salmon. The findings suggest that how insect feed is processed matters for fish gut health, which has implications for sustainable aquaculture practices.
