"The gut microbial community, called the gut microbiota, plays an important role in health for both humans and animals. The bacterial members of this community are the most numerous and consequently get the most attention in research. However, there are often overlooked but important fungi, viruses, archaea, and protozoa in the microbiota too. The fungal subset of a microbiota is called the mycobiota, and it is particularly understudied in birds. To close this gap, a recent study comprehensively characterized the mycobiota of chickens bred for meat. While gut bacterial communities typically stabilize with age, the chicken mycobiota was dynamic over time with no clear pattern of successive changes and low overall diversity. The upper gastrointestinal (GI) tract mycobiota was more diverse than the lower tract mycobiota, and just 25 core fungal groups accounted for more than 85% of the fungal population in each section of the GI tract..."

"Cost of feed is a major expense in chicken production, and that cost has been increasing due to overlap with human food and biofuel production. Therefore, improving feed efficiency can help reduce costs in chicken production systems. Both host genetics and gut microbiota can influence phenotypic traits like feed efficiency. New research explored this relationship in meat-type chickens by examining the host genetics as well as the microbiota from four intestinal regions and feces. Host relatedness showed little correlation to microbial community, but specific host genetic markers were associated with a small number of gut microbes. The greatest effect on feed efficiency, measured by residual feed intake (RFI), was host genetics. Out of the microbiota examined, only the cecum had a significant effect on the observed variance in RFI. Researchers also identified six bacterial groups associated with significant differences in feed efficiency..."

"Chickens are an important source of proteins for humans. Chicken diets are therefore formulated to enhance production efficiency and human health. But few studies have explored how industrial production system parameters affect certain pathogens in the chicken gut, such as Campylobacter, the leading cause of human foodborne bacterial gastroenteritis. A recent study examined how the presence of Campylobacter in the chicken gut microbiome varied across three different production systems, one based on a normal production system, and two based on higher welfare with and without omega-3. The standard production system produced a significantly different microbial composition than the other systems, with bacteria of the genus Alistipes playing a more prominent role in the gut microbiome of chickens from the normal production system, and Eisenbergiella playing a more prominent role in the other two production systems. These bacteria play active roles in energy metabolism and nutrient uptake..."

"Farmed chickens often suffer from intestinal inflammation which negatively affects their feed intake, digestion, and growth performance. The gut microbial community has a known close relationship with growth performance, but how, or if, this microbiota influences intestinal inflammation is not yet known. To test this, researchers examined the microbiota in young chickens, focusing on the jejunum section of the gut. They found that 7-week-old chickens with high body weight tended to have a microbiota dominated by gram-positive bacteria, like Lactobacilli. But lower-body-weight chickens had a microbiota dominated by gram-negative bacteria, like Escherichia-Shigella. Gram-negative bacteria carry endotoxin (lipopolysaccharide), and consequently, these lower body weight chickens had more of it in their bloodstream. These elevated lipopolysaccharide levels activated inflammatory cytokines in the jejunum, causing damage to the gut barrier..."
