TL;DR: In a 55-d backgrounding period, 120 British cross heifers (312 ± 20 kg) received diets containing 55% barley silage, 5% supplement and 0, 20, 40, or 60% of diet dry matter (DM) or at 60% plus additional calcium, provided as 1% limestone (n = 24), indicating the energy content of DDGS is similar to that of barley when included in backgrounding diets.

TL;DR: Silage samples were collected from bags after 115, 136 and 157 days of ensiling, compiled and used to determine in situ disappearance of DM and neutral detergent fibre (NDF) and inoculation accelerated the decline of silage pH.

TL;DR: The advent of metagenomic, metatranscriptomic, and proteomic techniques will further enhance the understanding of the enzymatic machinery involved in cell wall degradation and provide a holistic view of the microbial community and the complexities of plant cell wall digestion.

TL;DR: Differences in the AMR profiles among isolates reflected antimicrobial use practices in each sector of the One-Health continuum.

TL;DR: It is found that the ranch samples contained significantly fewer resistance mechanisms than dairy and feedlot samples, and that the resistome of dairy operations differed significantly from that of feedlots, suggesting that management of these effluents should be tailored appropriately.
