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.

Project description:Cistus ladanifer L. is a common shrub endemic to the Mediterranean that is highly concentrated in condensed tannins (CT). CT form complexes with dietary protein that resist microbial degradation in the rumen, which enhances dietary protein utilization in ruminant diets. The objective of this study was to evaluate the utilization of CT in the diet of lambs on the proteomes of muscle, hepatic and adipose tissues. Twenty-four white merino ram lambs were divided in three groups (n=8) fed on different diets: control (16% crude protein - CP), reduced protein (12% CP) and reduced protein treated with CT extract. At the end of the trial, lambs were slaughtered and the longissimus lumborum muscle, hepatic and peri-renal adipose tissues sampled. A two-way approach was used for shotgun proteomic analysis: 2D-DIGE (gel-based) and nanoLC-MS (gel-free). In the muscle, control lambs had lower abundance proteins that partake in the glycolysis pathway. With dietary 12 % CP, lambs had higher abundance of Fe-carrying proteins in the hepatic tissue. Lambs with dietary CT had higher abundance of hepatic flavin reductase. In the adipose tissue, control lambs had lower abundance of fatty-acid synthase. In conclusion, CT inclusion influences specific pathways in lamb tissues.
Project description:We perform transcriptomic sequencing of rumen, reticulum, omasum, and abomasum epithelial tissues from developing lambs. We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells at two time points (day5 and day10).
