International Genomic Cooperation - North American Perspective
Bibliographic record
Abstract
Centers in USA and Canada (AIPL-USDA, Animal Research Services, Beltsville, Maryland and the Canadian Dairy Network, Guelph, Ontario) have been sharing genotypes in order to enhance genomic evaluation procedures in both countries. Although genotypes and genomic methodology are shared, no direct comparison has been made between genomic breeding values published on the two country scales. January 2010 official proofs, direct genomic values and traditional EBV (termed PTA in USA) from both countries were compared. In general, genomic parent averages for young bulls were more correlated across countries than parent averages using traditional evaluations only. However, for LPI / Net Merit and Conformation, correlations across countries for first crop bulls and cows were stronger for traditional breeding values than for genomic breeding values. Accuracy of predicting future proofs was greater when all North American bulls were included in the SNP estimation, compared to only having domestic bull proofs available, with both countries realizing similar levels of accuracy. Gain in published reliability with inclusion of genomic information was greatest for young bulls and heifers evaluated in the USA, but this is also a function of differing methods used rather than differing levels of accuracy achieved with genomics. Proven bulls gained more published reliability in their second country of proof since the traditional EBV in that country would be a MACE evaluation of lower reliability so more gain is possible through genomics. This report summarizes the current benefits of collaboration in North America and challenges still to face.

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; both teacher heads agree on what is shown here.
