Timely Topics - Effects of Dietary Forage and Calf Starter Diet on Ruminal pH and Bacteria in Holstein Calves during Weaning Transition
This study demonstrated that feeding dietary forage alleviates subacute ruminal acidosis due to diurnal changes in ruminal pH.

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

Timely Topics - Progressive Colonization of Bacteria and Degradation of Rice Straw in the Rumen by Illumina Sequencing
This study evaluates the degradation pattern of rice straw by ruminal bacteria and identifies the bacteria that colonize rice straw during its digestion in the cow rumen.
