Circulating hormonal and gene expression profile in heat-stressed broilers divergently selected for high or low water efficiency
Warming climates and tightening water supplies are putting increasing strain on poultry production sustainability, especially in fast growing broilers that are highly susceptible to heat stress (HS). Boosting internal water use efficiency has therefore become a central goal for maintaining growth…

Integrated lipidomic and transcriptomic analysis of intramuscular fat deposition in yellow-feathered broilers
To elucidate the molecular basis of intramuscular fat (IMF) variation in yellow-feathered broilers, we selected 10 high-IMF (HF) and 10 low-IMF (LF) breast muscle samples from a total of 214 samples, after z-score filtering for LC-MS lipidomics and RNA-seq analyses. Lipidomics identified 94…

Effects of dietary energy and protein levels during brooding on performance, blood parameters, metabolome and gut microbiota in native chickens
The nutrient requirements of slow-growing native chickens during the critical brooding period are not well-defined, hindering the development of precision feeding strategies. This study aimed to systematically evaluate the effects of dietary metabolizable energy (ME) and crude protein (CP) levels…

Synergistic roles of follicle-stimulating hormone and testosterone in Sertoli cell proliferation and testicular function in roosters
Spermatogenesis relies on the intricate interactions between testicular somatic cells and germ cells. While follicle-stimulating hormone (FSH) and testosterone (T) are considered pivotal regulatory factors in this process, the mechanisms by which these hormones regulate the spermatogonial stem cell…

Edge-intelligent lightweight vision system for perspective-corrected egg-cage matching in cage-reared ducks
In the stereoscopic cage-rearing system, monitoring the individual egg production of laying ducks is essential for identifying low-yield individuals and optimizing breeding management. To overcome the high deployment cost of multi-sensor monitoring and the limited coverage of fixed cameras, this…

Effect of selenium yeast supplementation on drug metabolism genes, oxidative stress, and apoptosis in chicken liver after diquat induction: A proteomic perspective
Selenium yeast (SeY) is a commonly used beneficial additive in animal feed, but its effectiveness in reducing diquat (DQ)-induced liver damage remains uncertain. This study examined how selenium yeast affects drug-metabolism genes, oxidative stress, and apoptosis in chicken liver using proteomics…

Study on bacteriostasis of Chinese herbal medicine extracts to avibacterium paragallinarum
To explore the treatment of Chinese herbal medicine extracts on infectious rhinitis caused by Avibacterium paragallinarum, a strain of Avibacterium paragallinarum was isolated from the nasal cavity and infraorbital sinus of chickens suspected of infectious rhinitis, it was biologically identified…

Carbon footprint and environmental impact of poultry manure valorization as organic composts
Valorization of poultry manure (PM) has become increasingly important due to the rapid expansion of poultry production, with composting being the most widely used approach to convert PM into organic fertilizer (OF). Conventional composting (CC) typically requires approximately 40 days for manure…

Linking egg size, embryonic development, and post-hatch thermoregulatory responses in broilers from young and old breeders
This study evaluated how breeder age influences egg traits, embryonic development, and post-hatch thermoregulatory responses in broilers reared under thermoneutral conditions. Fertile Cobb 500® eggs from 34- and 63-week-old breeders were incubated under standardized conditions in a split-plot…

Effect of natural zeolite in diets with or without protein reduction on the performance, carcass and organ yield, and litter quality of broilers
Ammonia emissions from poultry litter represent a major environmental and production challenge in modern broiler systems and are strongly influenced by dietary crude protein levels and nitrogen utilization efficiency. Natural zeolites, particularly clinoptilolite, have been proposed as nutritional…

Enhanced oral bioavailability and antiviral efficacy of phillygenin via a self-nanoemulsifying drug delivery system in IBV-infected broilers
Infectious bronchitis (IB) poses a significant global economic threat to the poultry industry. Phillygenin (PHI), a lignan compound possessing antiviral activity, has its clinical application limited by poor aqueous solubility and low oral bioavailability. To overcome these limitations, a…

Depletion of CD25+ cells restores Th1, Th2 and Th17 responses and mitigates Eimeria maxima infection in chickens
Chicken coccidia can suppress the host immune response through CD4+CD25+ T cells, compromising the effectiveness of immune prophylaxis and potentially leading to immune failure. However, the role of chicken CD4+CD25+ T cells in chicken coccidia infection is not well understood. This study aimed to…

Risk analysis to reduce the appearance of antibiotic-resistant microorganisms in drinking water, dust and manure of broiler farms through adjustments of management measures
The treatment with antibiotics during the fattening of broilers has stagnated in Germany over the last years, while the national aim is to further reduce the use of antibiotics in human and veterinary medicine due to the occurrence of antibiotic-resistances in microorganisms. Therefore, the aim of…

Effects of Dietary Schizochytrium species powder on Broiler Growth Performance, Blood Parameters, and Gut Microbiota
This study investigated the effects of supplementing Ross 308 broiler diets with DHA-rich Schizochytrium sp. powder (SP) on growth performance, nutrient digestibility, serum biochemical parameters, and gut health. A total of 120 broilers were randomly assigned to four dietary treatments: the…

Host-derived Limosilactobacillus reuteri R30 and Cytobacillus solani Y5 improve growth performance and intestinal health of Danzhou chickens by regulating the jejunal microbiotaThe raw sequencing data generated in this study have been deposited in the Sequence Read Archive (SRA) at the National Center for Biotechnology Information (NCBI) under BioProject accession number PRJNA1489450. The data are publicly accessible at .
Intestinal health status is an important factor affecting of body weight (BW), and impaired growth performance is frequently associated with compromised intestinal barrier function. To address this issue, host‑derived probiotics were explored as an improvement strategy. Limosilactobacillus reuteri…
