Project description:Improvement of feed efficiency would increase profitability of the poultry industries by decreasing the amount of feed required for production. Korat (KR) chicken is a new alternative meat-type chicken breed which its meat is recognized for its high protein, low fat and low purine content, whereas its low feed efficiency leads to high cost of production. Deeper understanding on how feed efficiency influences meat quality is poorly elucidated. To fulfill deeper understand molecular key that point the variation in feed efficiency and meat quality, the aim of this study was to investigate molecular pathways and genes involved in feed efficiency and meat quality in thigh of slow-growing KR chicken. A total of 75 males KR chicken were reared in individual cage until 10 weeks of age. Individual feed intake and body weight were collected weekly to calculate Feed Conversion Ratio (FCR) and Residual Feed Intake (RFI). Meat quality parameters were measured in thigh muscles such as ultimate pH (pHu), water-holding capacity (WHC), drip loss (DL), nucleotides content and several biomolecules (amide, …). Base on extreme values of FCR at 10 weeks of ages, 12 birds from the high FCR group (HFCR) and 9 birds from the low FCR group (LFCR) were selected for investigating their transcriptome using an 8×60K Agilent chicken microarray. In addition, a weighted gene coexpression network analysis was performed to detect the relationship between modules of co-expressed genes and feed efficiency, meat quality in thigh muscle. The result in this study indicated that selection on feed efficiency (FCR, RFI) would affect flavor precursor, lipid and protein content in thigh muscle. Based on WGCNA and functional enrichment analysis, results suggested that the key molecular pathways relate to FCR, RFI and meat quality (WHC, DL, IMP, AMP and inosine) in thigh muscle were the pathways of regulation of biological process, biological regulation and regulation of metabolic. Moreover, we revealed four genes there are assembly competence domain (ACD) gene, baculoviral IAP repeat containing 5 (BIRC5) gene, cytochrome c oxidase assembly factor 3 (COA3) gene and myosin light chain 9 (MYL9) gene that might be biomarker gene in feed efficiency and meat quality in thigh muscle. The hypothesis of the current study was alteration feed efficiency in slow-growing chicken will impact meat quality especially in term of texture and flavor.

Project description:The objective of this study was to decipher the molecular basis of feed efficiency in meat-type chicken using duodenum tissues from a chicken population divergently selected for residual feed intake (RFI). Residual feed intake is the deviation of expected feed intake from actual feed intake. Chickens that consume less feed than expected are efficient (LRFI) and chickens that consume more feed than expected are inefficient (HRFI). A divergent selection for RFI was undertaken using an unselected random bred chicken population. RFI at day 35-42 was used as a criterion for selecting low (LRFI) and high (HRFI) RFI. Duodenum tissues were collected from 16 male chickens under sterile conditions experimentation. Tissues were collected from 4 males at days 35 and 42 in each line.

Project description:Slow-growing Korat chicken (KR) is an alternative to broiler chickens that has been used as a national tool to support smallholder farmers due to a higher selling price of KR meat. However, the individual variability of feed efficiency (FE) within a KR stockbreeding results in a lack of competitiveness. Therefore, improvement of FE of KR is of major importance to improve the profitability of livestock production enterprises. Here, we selected two groups of KR with divergent feed conversion ratios (FCR). We performed RNA-sequencing in order to profile KR jejunal transcriptome and to identify the transcriptional variations and biological pathways implied in response to divergent FCR. The biological pathways involved were revealed by enrichment of the Gene Ontology (GO) terms, and the Kyoto Encyclopedia of Gene and Genome (KEGG) pathways. The results showed that main pathways involved in KR FCR divergence were related to immune response, glutathione metabolism, vitamin transport and metabolism, lipid metabolism, and maturation, development and growth. This is the first study to investigate the molecular genetic mechanisms affecting the FCR values in jejunum of slow-growing chicken. This study will be useful in the line-breeding programs for slow growing chickens to improve FE in the stockbreeding and its profitability.

Project description:The increasing cost of conventional feedstuffs has bolstered interest in genetic selection for digestive efficiency (DE), a component of feed efficiency, assessed by apparent metabolisable energy corrected to zero nitrogen retention (AMEn). However, its measurement is time-consuming and constraining, and its relationship with metabolic efficiency poorly understood. To simplify selection for this trait, we searched for indirect metabolic biomarkers through an analysis of the serum metabolome using nuclear magnetic resonance (1H NMR). A partial least squares (PLS) model including six amino acids and two derivatives from butyrate predicted 59% of AMEn variability. Moreover, to increase our knowledge of the molecular mechanisms controlling DE, we investigated 1H NMR metabolomes of ileal, caecal, and serum contents by fitting canonical sparse PLS. This analysis revealed strong associations between metabolites and DE. Models based on the ileal, caecal, and serum metabolome respectively explained 77%, 78%, and 74% of the variability of AMEn and its constitutive components (utilisation of starch, lipids, and nitrogen). In our conditions, the metabolites presenting the strongest associations with AMEn were proline in the serum, fumarate in the ileum and glucose in caeca. This study shows that serum metabolomics offers new opportunities to predict chicken DE.

Project description:Transcriptome analysis was performed in duodenum of high and low RFI chicks for finding out differentially expressing genes and molecular pathways for RFI in colored broiler chicken. The sample of 4 birds each from high and low RFI group from the whole lot of 225 broilers was taken for transcriptome analysis. The expression of genes influencing low and high feed efficiency and the pathways of these genes was studied out to examine the molecular mechanism influencing feed efficiency.

Project description:Chicken anaemia virus (CAV) causes severe anaemia and immunosuppression in young chickens. Such effects reduce the efficiency of routine vaccinations while aggravating the effects of other pathogens in chicken populations. So far, the host responses to CAV have not been studied in vivo on a whole genome-wide scale. In this study, we compared gene expression profiles of chicken tissues (thymus, bone marrow, bursa of Fabricius and spleen-in vivo) from SPF chickens at 14-day-old following intramuscular inoculation at day-old. A chicken specific-immune microarray (5k) developed at Roslin Institute was used throughout the study. Statistically significant gene expression changes occurred mainly in the thymus (in vivo).
