ACUC Guideline The Use and Euthanasia Procedures of Chicken/Avian Embryos
Bibliographic record
Abstract
Avian embryos are not considered live animals under PHS policy. However, there is a consensus in the scientific community that at a certain point in development, avian embryos can experience pain. Because that exact point is not known for chicken embryos, chicken use and euthanasia guidelines differ across institutions. Cal Poly Pomona has chosen to adopt a guideline with the belief that pain occurs on or after gestation day 13, in anticipation of reviewing protocols including them. Therefore, with the adoption of this policy, studies involving the use of chicken embryos on or after gestation day 13 will require submission of a full ACUC Animal Use Protocol Application for review and approval. While other institutions develop their guidelines/policies on the embryo’s potential to hatch, Cal Poly Pomona’s Guideline is based upon the embryo’s potential to feel pain. According to the Canadian Council on Animal Care, “There is emerging evidence that indicates precocial oviparous species are conscious at hatching and during the last few days prior to hatching. ” This guideline takes this period before hatching into account and pertains to all use of chicken embryos, including research, teaching, or testing. The use of chicken embryos at gestation day 12 and younger does not require an ACUC Animal Use Protocol Application. However, PIs should be prepared for any potentials as outlined in this guideline.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
