Use of Bulk Tank Milk to Determine the Herd-level Prevalence of N. caninum in Dairy Herds on Prince Edward Island
Bibliographic record
Abstract
The apicomplexan protozoan parasite Neospora caninum is one of the most frequently diagnosed causes of bovine abortion. Transmission of the parasite occurs vertically from cow to calf with great efficiency, sustaining the infection within cattle herds for many generations. The herd-level prevalence of N. caninum on PEI is estimated to be 20.3%. This is relatively high compared to other Canadian provinces and research is needed to aid in the control of this infection on dairy farms. Serology is the only method available to diagnose N. caninum infection in live animals, but herd surveillance, using serology, is expensive and time consuming, especially in large dairy herds. The use of milk as a diagnostic tool could be very beneficial to the dairy industry, as it would allow for a fast and inexpensive way to test herds for N. caninum exposure. Furthermore, because the majority of dairy herds in PEI collect milk samples monthly (DHI; Dairy Herd Improvement), Neospora surveillance using milk would result in less stress on the lactating cow, and no special visits would be required to collect samples.

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.
