TL;DR: Mixed rumen bacteria deglycosylate steroidal saponin to sapogenin, at activity levels unaffected by prior exposure to sap onin, but they were unable to degrade the sapogen in core structure.

TL;DR: Antimicrobial susceptibility testing of five macrolides of M. bovis isolates found that >99% of isolates were resistant to tildipirosin and tilmicosin, regardless of the number and positions of the mutations, and the genotypes generated for 23S rRNA and the L4 and L22 ribosomal proteins were compared.

TL;DR: In vitro ruminal fermentation of ground and dry-rolled barley samples differing in starch content was evaluated using a batch culture technique as mentioned in this paper, and the results showed that both high starch and ground barley samples had greater gas production, short chain fatty acids (SCFA), dry matter (DM) and starch disappearance.

TL;DR: In this article, the HOLOS model has been developed (using country specific emission factors) to explore potential mitigation practices with respect to GHG emission reduction or increased carbon storage, which can create nutrient surpluses and thus other environmental hazards (e.g. for human and/or ecosystem health).

TL;DR: Results varied markedly depending on the modelling approach, emphasizing the importance of exploring and reporting multiple modelling methods based on a balanced consideration of important factors such as study design, mathematical appropriateness, research question and target audience.
