Vaccine usage in western Canadian cow-calf herds.
Bibliographic record
Abstract
The aims of this study were to describe when and how vaccines are administered during the production cycle in cow-calf herds in western Canada, as well as the factors that influence vaccine usage as reported by producers. The most commonly used vaccines were bovine viral diarrhea virus/infectious bovine rhinotracheitis (BVDV/IBR) in adult animals and clostridial vaccines in calves. While there has been improvement in usage of reproductive and respiratory viral vaccines since previous studies, there are still several areas in which uptake could be improved. Only 72% of herd owners vaccinated their bulls for at least 1 disease. Not all producers are vaccinating their calves for clostridial diseases, and 15% of producers did not vaccinate their calves for respiratory disease before weaning. One goal of increasing vaccine use is to obtain better infection prevention and control and decrease antimicrobial use in cow-calf herds. Two areas in which antimicrobials are commonly used, but vaccine uptake is limited, are foot rot in adult cows and diarrhea in calves.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
