Ruminal in situ disappearance and whole-tract digestion of starter feeds in calves before, during, and after weaning

By S. L. Gelsinger, W. K. Coblentz, G. I. Zanton, R. K. Ogden, and M. S. Akins

This study looks at the impact of different presentations of starter feed (pellet or texturized) on the evolution of total tract and rumen digestibility of DM, NDF, starch, and nitrogen. One key finding is the total tract nutrient disappearance decreases over time (especially with dry matter). Read

Changes in the rumen and colon microbiota and effects of live yeast dietary supplementation during the transition from the dry period to lactation of dairy cows

By A. Bach, A. López-García, O. González-Recio, G. Elcoso, F. Fàbregas, F. Chaucheyras-Durand, M. Castex

In this study, researchers made innovative use of endoscopy to sample rumen and colon tissues. This technique offered a unique perspective to study rumen microbiota. The resulting research details the effect of the rumen-specific yeast S. cerevisiae CNCM I-1077 on microbiota changes in both rumen and colon around transition. Read
