Comparison of DX613 copper sulfate acidifier footbath to a 5% copper sulfate footbath for prevention of digital dermatitis lesions in dairy cattle
Bibliographic record
Abstract
The objective of this study was to compare a 2.2% copper sulfate footbath with 325.31 mL of DX613 Acidifier (treatment; GEA Farm Technologies, Naperville, IL) to a 5% copper sulfate footbath (positive control) on the frequency and severity of DD in Holstein (n = 59) cows. The study was conducted at the University of Kentucky Coldstream Dairy from November 11, 2015 to January 20, 2016. Footbaths were delivered via a split footbath (Intra Care Foot Bath, Diamond Hoof Care LTD Alberta, Canada). The left side of the bath served as the positive control and the right side served as the treatment, cows were exposed to the solutions, five times per week. The DD lesions were scored biweekly using a M0 to M4 scoring system. A M0 score indicated no lesion (non-active lesions); M1 indicated small lesions (active lesions); M2 indicated large and potentially severe lesions (active lesions); M3 represented healing lesions (non-active lesions); and M4 represented chronic lesions (non-active lesions). The DD lesions were further separated into active lesions or non-active lesions for statistical analysis. A Chi-Square test calculated using the FREQUENCY procedure of SAS (SAS Institute, Inc., Cary, NC) indicated no-significant difference between the two concentrates (chi-square = 1.18, P = 0.56). A McNemar’s test indicated significant differences in the prevalence of lesions from the beginning to end of the study (treatment: P < 0.01, positive control: P < 0.01). The DX613 Acidifier may be a viable alternative for dairy producers.

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.
