TL;DR: In two pastures, two multiplex radio frequency (RF) mineral feeders equipped with load cells were used to monitor feeder attendance and individual intake of mineral by 33 and 36 cow-calf pairs individually identified by RF transponders.

TL;DR: The objective of this study was to determine the effect of replacing a mixture of canola meal and barley grain with corn-, wheat- or triticale dry distillers’ grains with solubles (DDGS) at 20% of dietary dry matter on in vitro ruminal fermentation in bovine ruminal fluid and on growth performance and carcass characteristics of lambs.

TL;DR: This approach reliably identified supplemental enzymes that enhanced sugar release from alkaline pretreated alfalfa hay and barley straw through formulation with synergetic recombinant enzymes.

TL;DR: A rapid method for the extraction of PCR-quality plant and microbial DNA from total rumen contents that is based on modifications in the cetyltrimethylammonium bromide procedure followed by cleanup using a Qiagen column is described.

TL;DR: It is suggested that tetracycline treatment of feedlot cattle can be associated with modest increases in risk for recovery of resistant NTSEC, but the numerous treatments with an advanced macrolide (tulathromycin) were not associated with detectable increases in resistance in NTSEC.
