Project description:To investigate genes involved in abdominal fat deposition and fat metabolism of broilers, we used highthroughput sequencing to detect the differentially expressed genes in livers and abdominal fats of broilers which were fed with a normal diet and a high-fat diet, respectively. The broilers began to fed with a normal or a high-fat diet in 1-week-old. After 7 weeks, the broilers were be executed and the livers and abdominal fats were used to extracted total RNAs. Finally, the total RNAs were be sequenced used BGISEQ-500 platform.

Project description:To investigate genes involved in abdominal fat deposition and fat metabolism of broilers with dw gene, we used highthroughput sequencing to detect the differentially expressed genes in livers and abdominal fats of dwarf broilers which were fed with a normal diet and a high-fat diet, respectively. The broilers began to fed with a normal or a high-fat diet in 1-week-old. After 7 weeks, the broilers were be executed and the livers and abdominal fats were used to extracted total RNAs. Finally, the total RNAs were be sequenced used BGISEQ-500 platform.

Project description:The aim of this study was to explore whether, and if so, how Bacillus subtilis KC1 can enhance the growth performance of broilers that have been adversely affected by Mycoplasma gallisepticum (MG) infection. A total of 96 1-day-old male broilers were randomly divided into 4 groups: the control group (basal diet), the MG group (basal diet + MG challenge), the Bacillus subtilis KC1 group (basal diet + Bacillus subtilis KC1 supplementation), the Bacillus subtilis KC1 + MG group (basal diet + Bacillus subtilis KC1 supplementation + MG challenge). The trial lasted 42 days, and the results showed that the MG group had significantly reduced body weight and average daily gain, as well as increased feed conversion ratio of broilers, compared to the control group. Dietary supplementation with Bacillus subtilis KC1 significantly improved the growth performance of MG-infected broilers. In addition, dietary supplementation with Bacillus subtilis KC1 significantly improved oxidative stress and inflammatory response markers, characterized by increased superoxide dismutase levels and reduced levels of malondialdehyde, interleukin-1β, and tumor necrosis factor-α. Furthermore, both metabolomics and transcriptomics analyses indicated that MG infection markedly disrupted amino acid metabolism in broilers, whereas Bacillus subtilis KC1 supplementation alleviated the abnormal amino acid metabolism caused by MG infection. These results suggested that Bacillus subtilis KC1 may alleviate the poor growth performance caused by MG infection in broilers by improving amino acid metabolism.

Project description:In the current study, we expanded our previous work to identify miRNAs implicated in the myogenesis regulation through the comparison of miRNAs transcriptome in skeletal muscle tissues between broilers and layers. To address that, we firstly performed Solexa deep sequencing to profile miRNAs expressed in chicken skeletal muscle tissues. Sequence tags analyses not only enable us to report a group of highly abundant known miRNAs expressed in skeletal muscles but most importantly to identify novel putative chicken miRNAs from skeletal muscle tissue. Further miRNA transcriptome comparison and real-time RT-PCR validation experiments revealed seveal differentially expressed miRNAs between broilers and layers.

Project description:The genetic closeness and divergent muscle growth rates of broilers and layers make them great models for myogenesis study. In order to discover the molecular mechanisms determining the divergent muscle growth rates and muscle fiber sizes in different chicken lines, we systematically identified differentially expressed genes between broilers and layers during muscle development (postnatal 1 day, 2 weeks, 4 weeks, 6 weeks and 8 weeks) by microarray hybridization experiment. Taken together, 543 differentially expressed probe sets were found between broilers and layers across different developmental stages, including genes related to muscle growth and hypertrophy, fatty acid transportation and metabolism, protein degradation, and several important signaling pathways. The expression profiles of a few differentially expressed genes were highly correlated with the growth rates of broilers and layers. We also identified SNPs within upstream transcription factor binding sites of a few differentially expressed genes, indicating that these SNPs might be the causing factor of the expression differences of these genes between broilers and layers. These studies provided new clues for deciphering mechanisms underlining muscle development and organ size control in different chicken lines, will shed light on the study of human muscle related disease as well. Experiment Overall Design: Pectoralis major muscles were sampled from broilers and layers at indicated developmental stage (postnatal 1 day, 2 weeks, 4 weeks, 6 weeks and 8 weeks). Trizol extraction of total RNA was performed according to the manufacturer's instructions. Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 2 ug total RNA. Affymetrix Gene Chip array hybridization was carried out according to Affymetrix Expression Analysis Technical Manual by GeneTech Biotechnology Limited Company (Shanghai, China). Following labeled cRNA fragmentation, 15 ug of cRNA were hybridized for 16 hr at 45â on Affymetrix Chicken Genome Array. After standard washing and staining, GeneChips were scanned using the Affymetrix GeneChip Scanner 7G.

Project description:The broilers were randomly allotted to four treatment groups (Con, DEX, P8, and DEX+P8 groups) with 10 replicates per group (10 broilers per replicate). Broilers in the Con and DEX groups were fed a basal diet. Broilers in the P8 and DEX+P8 groups were fed a basal diet containing 1 × 108 CFU/g P8. At 16 days of age, broilers in the DEX and DEX+P8 groups were injected with 3 mg/kg body weight DEX (200 μL), whereas broilers in the Con group were injected with an equal volume of saline.
