A Rapid Scoping Review of Nutritional Management of Beef Cows and Pre-Weaning Calves and the Occurrence of Bovine Respiratory Disease in Pre- and Post-Weaning Calves in North America.
Review in Animals : an open access journal from MDPI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bovine respiratory disease (BRD) causes economic loss and antimicrobial use in North American beef production. This rapid scoping review examined whether nutritional management of beef cows and pre-weaning calves affects BRD morbidity or mortality before or after weaning. Eligible sources were English- or French-language North American studies published from 2000 onward that evaluated nutrition or colostrum management in beef cows or calves and reported BRD-specific, secondary, or tertiary outcomes. Six bibliographic databases and grey-literature sources were searched. One reviewer charted and verified data using a pre-tested form. Findings were synthesized narratively without formal critical appraisal. Forty-seven studies were included: 22 reported BRD-specific morbidity or mortality, 20 reported only secondary outcomes (e.g., crude mortality), and five reported only tertiary outcomes (e.g., vaccine antibody titres). Three of five controlled trials of maternal protein supplementation reported favourable offspring BRD outcomes, although incomplete comparisons, absent treatment effect estimates, and the absence of formal critical appraisal limited interpretation. Selected maternal trace mineral trials reported reduced post-weaning BRD morbidity or fewer aggregated sick incidents. Direct evidence for colostrum-management strategies was sparse; other findings were inconsistent or based on few or no BRD events. Evidence remains insufficient for specific recommendations. Adequately powered commercial trials should report prespecified BRD outcomes, effect sizes, and confidence intervals.
