Abstract
This study investigates the impact of heat stress, measured by daily temperature-humidity index (THI), on the reproductive performance of native Algerian cows. We analysed fertility metrics from 3,847 artificial inseminations performed on 2,130 Atlas Brown cows. Results showed a total pregnancy rate (TPR) of 58.97%, a first-service conception rate (CR1stAI) of 24.41%, and a second-service conception rate (CR2ndAI) of 36.71%. Severe THI levels (>80) significantly decreased TPR by 26% and CR1stAI by 46%, but low and moderate THI had no significant impact. Heat stress did not significantly affect CR2ndAI and repeat breeding cows (RBC), though moderate and severe heat stress decreased CR2ndAI, and severe heat stress increased RBC. Moderate heat stress reduced the proportion of cattle with <30 days reproductive period. The study shows that Atlas Brown cattle are susceptible to high THI levels and perform well under low and moderate heat stress, suggesting the potential utility of indigenous breeds in high-THI regions.

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
