Evaluation of Colostrum Quality, Passive Immunity, and Dairy Calf Management Practices in Alberta
Bibliographic record
Abstract
Failure of passive transfer of immunity (FPT) in dairy calves is associated with increased risk of morbidity and mortality. In this study, which involved 14 dairy farms in central Alberta, 44.2% of calves had FPT when serum total protein was used as a measure while 27.8% had FPT when serum immunoglobulin G (IgG) was used. Risk of FPT was associated with amount of colostral IgG consumed. Low risk of FPT was associated with feeding a combination of waste, sale, and milk replacer as the second feeding after colostrum. Higher risk of FPT was associated with feeding a colostrum supplement compared to frozen-thawed or colostrum replacer. Tube feeding of colostrum was associated with reduced growth and increased risk of death. Both the Brix refractometer and colostrometer are suitable tools to indirectly measure colostral IgG when used at cut points of 23% and 80 mg/mL, respectively.

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.
