Project description:Total RNA from rumen epithelial tissues of cows fed alfalfa hay (AL),Rice straw (RS) or Corn stover (CS)diet were sequenced using Illumina Hiseq 2000 system. For comparative analysis, differentially expressed genes were identified with edgeR.
Project description:A healthy rumen is crucial for normal growth and improved production performance of ruminant animals. Rumen microbes participate in and regulate rumen epithelial function, and the diverse metabolites produced by rumen microbes are important participants in rumen microbe-host interactions. SCFAs, as metabolites of rumen microbes, have been widely studied, and propionate and butyrate have been proven to promote rumen epithelial cell proliferation. Succinate, as an intermediate metabolite in the citric acid cycle, is a final product in the metabolism of certain rumen microbes, and is also an intermediate product in the microbial synthesis pathway of propionate. However, its effect on rumen microbes and rumen epithelial function has not been studied. It is unclear whether succinate can stimulate rumen epithelial development. Therefore, in this experiment, Chinese Tan sheep were used as experimental animals to conduct a comprehensive analysis of the rumen microbiota community structure and rumen epithelial transcriptome, to explore the role of adding succinate to the diet in the interaction between the rumen microbiota and host.
Project description:SARST-V1 method was used to asses the effect of live yeast on the microbial population of the rumen of cows fed an acidogenic diet 3 cows were used in 3 by 3 latin-square design with 3 periods. In each period animals received either 0.5g/d of yeast, 5g/d of yeast or none. Rumen microbiota was analysed using the SARST-V1 method for each period.
Project description:Total RNA from duodenum, jejunum, liver and mammary gland tissues of cows fed alfalfa hay (AL),Rice straw (RS) or Corn stover (CS) diet were sequenced using Illumina HiSeq 2000 system. For comparative analysis, differentially expressed genes were identified with edgeR and SAS software.
Project description:We assessed the transcriptomic adaptation of the calf rumen epithelium to changes in ruminal pH caused by feeding calf starter with and without forage during weaning transition. The calves were divided into a gorage provision group (HAY group, n = 3) and forage non-provision group (CON group, n = 4) 3 weeks after weaning.
Project description:In this study, we studied the fibrolytic potential of the rumen microbiota in the rumen of 6 lambs separated from their dams from 12h of age and artificially fed with milk replacer (MR) and starter feed from d8, in absence (3 lambs) or presence (3 lambs) of a combination of the live yeast Saccharomyces cerevisiae CNCM I-1077 and selected yeast metabolites. The fibrolytic potential of the rumen microbiota of the lambs at 56 days of age was analyzed with a DNA microarray (FibroChip) targeting genes coding for 8 glycoside hydrolase (GH) families.
