Summary: This study aimed to identify metabolite biomarkers for Salmonella Enteritidis contamination in chicken meat. Through untargeted metabolomics analysis, 30 potential biomarkers for Salmonella enteritidis contamination in chicken meat were identified. Quantitative analysis confirmed 10 candidate metabolite biomarkers, among which 5 were identified as biomarkers for Salmonella Enteritidis contamination in chicken. These results provide a potential theoretical basis for developing Salmonella Enteritidis detection methods in raw chicken.

Summary: This study investigated the development regulation of the uterine-vaginal junction (UVJ) epithelial folds in female birds and its crucial role in sperm storage and fertilization. The study classified the development of UVJ folds into 4 stages based on morphological characteristics. RNA-seq analysis identified different stages of regulation and genes involved in cell proliferation, differentiation, polarity, migration, adhesion, and junction during UVJ fold formation. The study also found significant differences between different cell types within UVJ, and highlighted the importance of genes in the TGF-beta and WNT pathways in regulating epithelium proliferation and differentiation for UVJ fold formation. This research provides new insights into the differential regulation of fertilization traits from a developmental biology perspective.

Summary: RyhB-1 and RyhB-2 are small non-coding RNAs that regulate iron homeostasis in Salmonella by sensing iron concentration in the environment. They inhibit the growth of Salmonella Typhimurium in macrophages by modulating the expression of genes sicA and rtsB. The regulatory role of RyhBs and their targets in Salmonella Enteritidis is not well understood. We found that RyhB paralogs are expressed when Salmonella Enteritidis interacts with chicken macrophages. They downregulate survival-related virulence factors and attenuate the survival of Salmonella Enteritidis inside macrophages.

Summary: The immunometabolic role of antibiotics and plant extracts was studied on a chicken macrophage-like cell line during a Salmonella Enteritidis infection. Oxytetracycline, thyme essential oil, and capsicum oleoresin showed no significant impact, while garlic oil affected glycolysis. Gentamicin and grape seed extract exhibited the best immunometabolic profile, helping the host with immune response activation and maintaining a less inflammatory status metabolically.

Summary: The study analyzed TLR genes from the genomes and transcriptomes of 102 amphibian species to understand their evolutionary patterns. Results showed that TLR genes can be divided into seven subfamilies, with TLR4 subfamily found only in Anura. Purification selection played a leading role in amphibian TLR evolution, and different domains had different evolution rates. Positive selection patterns and single-nucleotide polymorphisms were observed in TLR genes.

Summary: This study aimed to explore the complex interactions among chicken, Salmonella, host-microbiome, and associated metabolites using transcriptome data from the chicken cecum. The researchers identified driver and hub genes highly correlated with factors that confer resistance to Salmonella infection. Additionally, the PPAR and oxidative phosphorylation metabolic pathways were found to be involved in the host's immune response against Salmonella colonization at different stages post-infection. This study provides valuable transcriptome profiles and a mechanistic understanding of the complex interactions.

Summary: Sexual maturation is crucial for reproduction and production performance, and heterosis has been widely used in animal crossbreeding. This study investigated the molecular mechanism of sexual maturation heterosis by analyzing ovary lncRNAs and mRNAs in purebreds and crossbreeds. Nonadditive lncRNAs and genes were found to play a significant role in crossbreeds, and the biological processes and pathways they were involved in were related to sexual maturation. This research provides a basis for genetic improvement of sexual maturation traits.

Summary: This paper examines the economic performance of small ruminant farms using data from Greek sheep and goat farms, finding that grazing may not necessarily improve economic efficiency, with less grazed farms generally being more efficient. Greater organization is needed to ensure grazing has a positive economic impact on farms, including better accessibility to pastures, efficient rations, and training.

Summary: The European sheep meat sector is facing technical, market and financial challenges that threaten its economic performance and overall sustainability, largely due to poor and slow adoption of innovations. The most efficient sheep meat farms in France, Spain and the UK were found to rear large flocks, utilize available infrastructure at full capacity, and manage human labor rationally, while emphasizing feeding and grazing innovations, marketing strategies, breeding programs, and digital technologies. Adoption of best practices, modern technologies and innovations is crucial for the sector's future sustainability and resilience.

Summary: Managing a milk zone in the dairy industry is challenging due to the difficulty in acquiring necessary data in an organized and standardized manner. However, the use of software practices can add value to the data and improve milk production and processing. FarmDain is a web-based application that utilizes state-of-the-art software technologies to digitize the value chain and facilitate data acquisition, processing, and visualization in sheep and goat management. Its implementation in a dairy sheep farm resulted in lower feeding cost and improved overall farm performance through targeted decision-making based on app-generated reports.
