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:Microbiota from rats fed with wheat aleurone and plant omega fatty acids In this study we investigated how an AX-rich WA and ALA from linseed oil (LO) modulate the gut microbiota of rats. Wistar rats were fed a standard diet and received either an iso-energetic control oil (PO), control oil + aleurone (A+PO), linseed oil (LO) or linseed oil + aleurone (A+LO) during 12 weeks. Feacal samples were recovered after the 12 week treatments. DNA extractions were performed using using the Qiagen's DNA Stool Kit (Qiagen, West Sussex, UK). 10ng of DNA template were amplified by PCR (16S gene) and purified using Qiagen's Qiaquick PCR purification kit (Qiagen, West Sussex, UK). 1ug of purified PCR product were labelled with either Cy3 or Cy5 using Genomic DNA ULS Labelling kit (Agilent Technologies, Palo Alto, CA). 250ng of labelled DNA were hybridized on the microarray for 24h at 65M-BM-0C. Washings were performed as recommended by the manufacturer. Microarray scanning was performed on a Surescan Microarray scanner (Agilent Technologies, Palo Alto, CA). Data were extracted using the Feature extraction software (Agilent Technologies, Palo Alto, CA). The retained intensity value for each probe was the ratio between the spotM-bM-^@M-^Ys median intensity signals and the median of background signals. A 13 chip study was realized to analyze the feacal microbiota of rats treated with either an iso-energetic control oil (PO), control oil + aleurone (A+PO), linseed oil (LO) or linseed oil + aleurone (A+LO) during 12 weeks. Each microarray corresponding to hybridization with 250ng of labelled 16S rRNA gene amplicons from 2 rat DNA faecal samples. Microbiota structure and diversity were assessed using the HuGChip (Tottey et al., 2013). Each probe (4441) was synthetized in three replicates. On the same array, 2 different samples were hybridized. One labelled with the Cy3 dye and one with the Cy5 dye. The results were processed as single channel (13 raw data files available on Series records for 25 samples).

Project description:The aim of this study was to determine the effects of linseed dietary supplementation on gene expression in the mammary gland of grazing dairy cows. Milk composition and gene expression in the mammary gland tissue were evaluated in dairy cows supplemented with linseed. The linseed supplementation improves the health and nutrition quality aspects of dairy milk, but also affects the gene networks expression signature associated with cellular growth and proliferation, cell-death, signalling, nutrient metabolism, and immune response, and in turn, the mammary gland integrity and health. The experiment was carried out in a complete randomized blocked designed structure comprising 14 Holstein-Friesian cows (6 second parity, 2 third parity and 6 older cows), selected from a 550-cow herd. Cows were paired in 7 blocks on the basis of similarity in parity (second parity, third parity and older cows), expected date of calving, and milk performance in the previous lactation (in order of priority). Cows within each block were randomly allocated to one of two treatment groups, “Omega” or “Control”. The dietary Omega treatment consisted of a basal diet supplemented with a concentrate-mixture including linseed on a dry matter (DM) basis, whereas cows in treatment group Control were supplemented with a concentrate mixture without linseed. Linseed was chosen because it is rich in c9,c12,c15-18:3 (ALA). Concentrate mixtures were fed with a concentrate dispenser. Experimental treatments started 3 weeks before the expected calving date (wk -3) and lasted until 6 weeks after calving (wk 6).
