Comparison of tilmicosin to gamithromycin for on arrival treatment of bovine respiratory disease in feeder steers
Bibliographic record
Abstract
A trial was conducted in a commercial feedlot in western Canada using fall-placed feedlot calves at moderate risk of bovine respiratory disease (BRD) to compare the efficacy of gamithromycin to tilmicosin for metaphylactic treatment of BRD. First-pull treatment rates for BRD were significantly lower (P=0.01) in calves in the gamithromycin group than in the tilmicosin group. There were no other significant differences in health or performance between the two groups. The 6.6 percentage point difference in treatment rates for BRD equated to a net advantage of $0.03 CAN/head for those calves given gamithromycin as a metaphylactic drug on arrival compared to metaphylactic treatment with tilmicosin. Drug cost and disease risk should be carefully evaluated in each feedlot and group of incoming cattle to determine the most cost-effective metaphylaxis protocol.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
