Assessment of redox markers in cattle
… redox status may have important implications to cattle health and production. Antioxidants and biomarkers of oxidative stress were evaluated in cattle under three phases of management. Each phase stood alone as a treatment model, and managerial aspects during the phase were evaluated as potential …

Asian long-horned tick distributions in Virginia pastures and evaluating the horn fly as a possible vector of Theileria orientalis Ikeda
… its role as the primary vector of the emerging cattle parasite, Theileria orientalis Ikeda. To better understand the transmission landscape in Virginia, this study first evaluated the fine-scale environmental drivers of H. longicornis density. Across two field seasons (2023–2024), 25,929 ticks …

The fate of neonate calves. A discussion of the bovine infant health implications of dairying in antiquity, using archaeozoological studies of six Orcadian contexts.
A methodology for ageing foetal and neonatal cattle is developed, involving radiographic examination of infant mandibles for early developmental stages in molariform teeth; tooth-wear methodologies are imprecise at this stage before wear commences. Known-age modern bovine foetal and neonate …

Effect of Yeast Supplementation During Various Stages of Beef Production
… supplementation affects growth performance and health during this time. In experiment 1, 2 truckloads of highly stressed calves (n = 175; initial body weight [BW] = 226 ± 24.5 kg) were assigned randomly to 1 of 3 treatments; unsupplemented control, or supplementation with 2 commercial yeast …
