Proteomics investigation reveals breed specific responses to environmental enrichment and broiler meat quality

ABSTRACT: This study, conducted as part of the mEATquality European Union project, used a large intervention experiment to examine the main effects and interactions of extensification factors in higher-welfare, non-organic systems with relatively low chicken stocking density. The study focused on how chicken genetics and on-farm enrichments (as two extensification factors) influence broiler performance, intrinsic meat quality and the molecular mechanisms underlying these traits with the aim of supporting improved production strategies.

The meat industry faces growing pressure to adopt sustainable and welfare-friendly practices. This study used mass spectrometry-based proteomics to examine the effects of genetics and on-farm environmental enrichment on broiler performance and meat quality. Slower-growing (SG; Hubbard S757N) and faster-growing (FG; Hubbard JA787) broilers were raised in enriched and non-enriched environments within higher-welfare systems. The SG broilers showed higher expression of detoxification and cytoskeleta ...[more]

Meat quality changes as measured by proteomic responses in chicken muscle after a diet with or without fibre and with or without space restrictions.

Project description:This study, conducted as part of the mEATquality European Union project, examined the main effects and interactions of space allowance and dietary fibre provision in higher-welfare systems. Using the slower-growing genotype, Hubbard JA757, we assessed broiler performance, intrinsic meat quality and the molecular mechanisms underlying these outcomes. These findings highlight how husbandry factors interact to shape meat phenotypes, offering a molecular framework to support quality-focused, welfare-aligned, and environmentally conscious meat production.

Comparative Muscle Proteomics in Organic and Conventional Broiler Chickens: Uncovering Biomarkers of Stress and Meat Quality

Project description:This study investigates the impact of stress on muscle physiology and meat quality in broiler chickens by comparing protein expression profiles between organic and conventional farming systems using label-free quantitative (LFQ) proteomics. Muscle samples were analyzed via nanoLC-ESI-MS/MS coupled with comprehensive bioinformatics to identify differences in protein abundance associated with rearing conditions.A total of 7,221 proteins were identified, with 1,645 proteins upregulated and 1,612 downregulated in organic chickens compared to conventional ones. Functional analyses including Gene Ontology (GO) and STRING network analyses revealed that proteins upregulated in organic chickens were predominantly involved in oxygen transport, oxygen binding, and muscle structural organization, indicating enhanced oxygen metabolism and muscle development consistent with improved animal welfare. Conversely, proteins related to ribosomal function and RNA binding were enriched in conventional chickens, suggesting stress-related alterations in protein synthesis. KEGG pathway analysis showed significant enrichment of carbon metabolism, amino acid biosynthesis, nitrogen metabolism, and the tricarboxylic acid (TCA) cycle pathways in organic chickens, while glycolysis, gluconeogenesis, and ribosomal pathways were downregulated. Key differentially expressed proteins identified as potential biomarkers distinguishing organic from conventional meat include downregulated PGM1, AMPD1, LDHA, ENO3, and PKLR, and upregulated COL1A1, COL1A2, TTN, TPM2, CA3, MB, HSPB1, ACO2, ACAA2, and TF. These proteins are involved in muscle structure and energy metabolism and may serve as indicators of meat quality linked to stress and welfare conditions. Overall, this proteomic analysis provides novel insights into how stress modulates the muscle proteome in broiler chickens and supports the adoption of welfare-focused organic poultry production practices to improve meat quality.

Differential gene expression in the bone marrow of 60 week old layer and broiler chickens

Project description:Osteoporosis is a major problem for the laying hen industry due to welfare issues and economic losses related to bone fractures. The objective of this research was to better understand genetic influences on bone integrity by comparing gene expression profiles from bone marrow of chickens expressing phenotypic differences for a number of bone characteristics. Global expression profiles of genes included on the Fred Hutchinson Cancer Research Center (FHCRC) Chicken 13K array were assessed in broiler and layer chickens. Keywords: Gene expression comparison between two chicken lines at 60 weeks of age

Effect of an immune challenge and feed supplements on broiler chicken individual breast muscle protein synthesis

Project description:Optimization of broiler chicken breast muscle protein accretion is key for the efficient production of poultry meat, whose demand is steadily increasing. In a context where antimicrobial growth promoters use is being restricted, it is important to find alternatives as well as to characterize the effect of immunological stress on broiler chicken growth. Despite of its importance, research on broiler chicken muscle protein dynamics has been mostly limited to the study of mixed protein turnover. The present study aims to characterize the effect of a bacterial challenge and the feed supplementation of a citrus and a cucumber extract on broiler chicken individual breast muscle proteins fractional synthesis rates (FSR) using a recently developed dynamic proteomics pipeline. 21 day-old broiler chickens were administered a single 2H2O dose before being culled at different timepoints. A total of 60 breast muscle protein extracts from five experimental groups (Unchallenged, Challenged, Control Diet, Diet 1 and Diet 2) were analyzed using a DDA proteomics approach. Proteomics data was filtered in order to reliably calculate multiple proteins FSR making use of a newly developed bioinformatics pipeline. Broiler breast muscle proteins FSR uniformly decreased following a bacterial challenge, this change was judged significant for 15 individual proteins, the two major functional clusters identified as well as for mixed breast muscle protein. Citrus or cucumber extract feed supplementation did not show any effect on the breast muscle protein FSR of immunologically challenged broilers. The present study has identified potential predictive markers of breast muscle growth and provided new information on broiler chicken breast muscle protein turnover which could be essential for improving the efficiency of broiler chicken meat production.

Project description:The expression of genes were analysed in 7th day of embryonic stage between Aseel, an indigenous slow-growing chicken, and control broiler, a fast-growing broiler chicken line. The whole embryo was collected in TRIZOL and total RNA was isolated. The expression profile of gene was determined in 64k Agilent chicken microarray chip. The Cy3 dye was used for detection. The fold change of expression was analysed in Aseel as compared to broiler chicken line.

The dynamic methylome of the broiler chicken as a resource for livestock performance biomarker development

Project description:The broiler chicken is the globally most important source of commercially produced meat. While genetic approaches have played an important role in the development of chicken stocks, little is known about chicken epigenetics. We have now systematically analyzed the chicken DNA methylation toolkit and DNA methylation landscape. While overall DNA methylation patterns were similar to mammals, sperm DNA appeared distinctly hypomethylated, which correlates with the absence of the DNMT3L cofactor in the chicken genome. Additional analysis also revealed the presence of low-methylated regions in the chicken methylome, which are conserved gene regulatory elements that show tissue-specific methylation patterns. We also used whole-genome bisulfite sequencing to establish 56 single-base resolution methylomes of the broiler chicken from various tissues and developmental time points. Data analysis confirmed tissue-specific and time-dependent methylation patterns that were used to establish a DNA methylation clock to predict sample age and measure stock performance. Our study thus provides a comprehensive resource for the chicken methylome and establishes a novel epigenetic tool for livestock performance analysis.
