Abstract
Hatching eggs from three broiler breeder flocks that had experienced losses from myeloid leukosis were tested for infection with avian leukosis virus of subgroup J (ALV-J). Sufficient eggs were positive in two flocks to relate infection to egg weight. Allantoic fluid, embryonic tissue and yolk were collected after 18 days of incubation. The albumen and allantoic fluid were tested by enzyme-linked immunosorbent assay (ELISA) for group-specific (gs) antigen and all specimens were inoculated onto cell cultures to test for virus by immunofluorescence assay. Virus detected was identified as ALV-J by polymerase chain reaction techniques. The percentage of eggs that tested positive for gs antigen and virus was higher in those that weighed under 60 g than in heavier eggs (P < 0.01). In one flock, antibody to ALV-J was detected by ELISA in yolk from 14 and 43% of the eggs that tested positive or negative for virus, respectively. Testing the same eggs for antigen, virus and antibody should be useful for establishing the status of infection of the hens.

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 it
