Correlation of carbohydrate larval antigen (CarLA®) antibody response with parasitism in Ontario sheep
Bibliographic record
Abstract
Gastrointestinal nematode parasites (GINs) are a significant cause of morbidity, mortality and loss of productivity on North American sheep farms. In light of the rising prevalence of anthelmintic resistance, selection of animals with a superior immune response to GINs has received considerable attention. In New Zealand, measurement of salivary antibody to a carbohydrate larval antigen (CarLA®, AgResearch Inc.) has been used successfully to identify sheep with superior immunity. However, climate and GIN epidemiology in Ontario are different from New Zealand, and sheep are generally not exposed to GINs for several months during housing over winter. To date, CarLA® has not been evaluated in North America. The purpose of this study was to determine whether Car LA® correlates with parasite burden under temperate grazing conditions in Ontario.

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.
