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:We recently performed global gene expression in the breast muscles of modern broiler and foundation line chickens. In this study, we have peformed miRNA expression analyses in the same tissues to identify muscle specific miRNAs that could be regulatory factors for muscle growth and feed efficiency in chickens.

Project description:Domestic broiler chickens rapidly accumulate adipose tissue due to intensive genetic selection for rapid growth and are naturally hyperglycemic and insulin resistant, making them an attractive addition to the suite of rodent models used for studies of obesity and type 2 diabetes in humans. Furthermore, chicken adipose tissue is considered as poorly sensitive to insulin and lipolysis is under glucagon control. Excessive fat accumulation is also an economic and environmental concern for the broiler industry due to the loss of feed efficiency and excessive nitrogen wasting, as well as a negative trait for consumers who are increasingly conscious of dietary fat intake. Understanding the control of avian adipose tissue metabolism would both enhance the utility of chicken as a model organism for human obesity and insulin resistance and highlight new approaches to reduce fat deposition in commercial chickens. In the present study we simultaneously characterized the effects of a short term (5 hours) fast or neutralization of insulin action (5 hours) on adipose tissue of young (16-17 day-old), fed commercial broiler chickens.

Project description:Male Ross 308 broiler chickens (Gallus Gallus) were raised with ad libitum access to a pelleted wheat/maize diet from the 10th day of age. Breast muscle was acquired from the chickens at 36 days post-hatching. The degree of wooden breast (non-affected, moderately affected and affected) were first sorted by palpation of individual chickens, followed by classification using near-infrared (NIR) spectroscopy of breast filet and histology of specimen. Samples were grouped into three categories: affected, moderately affected and non-affected according to WB myopathy based on the connective tissue content (fibrotic signs). For the shotgun proteomics analysis, salt soluble proteins were extracted from breast filet. Twelve biological replicates of each group were included in the analysis. The proteins were reduced and alkylated prior to digestion with Trypsin/Lys-C. And peptides were analyzed by Dionex Ultimate 3000 UHPLC (Thermo Scientific) coupled to a Q-Exactive hybrid quadrupole Orbitrap mass spectrometer (Thermo Scientific).

Project description:The embryo to neonate transition is a critical period of development that has significant impact on broiler production. During this time important genetic programs governing metabolism and growth are established. The goal of this work was to study the effects of early post-hatch (PH) development and time of initiation of feeding on activation of the genetic programs regulating tissue growth and metabolism in liver, brain, duodenum and breast muscle in broiler chickens. We used chicken genome GeneChip microarrays in a replicated experiment to detail the global program of gene expression in liver, whole brain, duodenum and breast muscle during the post-hatch transition in response to the initiation of feeding.

Project description:Necrotic enteritis (NE) in broiler chickens, caused by the overgrowth of toxin-producing strains of Clostridium (C.) perfringens, results in the development of necrotic lesions, compromised intestinal health, and significant economic losses in poultry production. This study aims to analyze the blood proteome of broiler chickens affected by NE, providing insights into the host's response to the infection. Using MS/MS-based proteomics, blood plasma samples from broilers with necrotic lesions of different severity were analyzed and compared to healthy controls. A total of 412 proteins were identified, with 63 showing significant differences and (for some of those) correlating with disease severity. Gene Set Enrichment Analysis (GSEA) revealed that proteins affected by NE were predominantly associated with the immune and signaling processes and extracellular matrix (ECM) structures. Notably, regulated proteins were significantly involved in bioprocesses related to complement activation, acute phase reaction, proteolysis and humoral immune response. The findings suggest that the changes in plasma proteins in response to NE are driven by the host's intensified efforts to counteract the infection, demonstrating a.o. a notable reduction in peptides from ECM-related proteins in the blood of NE-affected birds. Overall, proteomics results underscored the attempts of the host to manage tissue damage and inflammation, indicating a coordinated effort to mitigate the pathogenic impact of C. perfringens. This study provides a deeper understanding of the host-pathogen interactions and potential targets for therapeutic intervention.

Project description:We investigated the effects of heat stress on the liver transcriptome of 3wk-old chicks of a broiler line, the Fayoumi and an advanced intercross line (AIL). Transcriptome sequencing of 48 male chickens using Illumina HiSeq 2500 technology yielded an average of 3.4 million, 100-base -pair single-end, reads per sample.
