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: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: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.
