Alpaca embryo transfer on a private Canadian farm
Bibliographic record
Abstract
This study evaluated the feasibility of using an embryo transfer protocol in an alpaca farm in Canada. Alpaca donors and recipients were synchronized with 2 doses of gonadotrophin-releasing hormone (GnRH), 12 days apart. In donors (n = 5), superstimulation was induced with follicle stimulating hormone (FSH) given daily (40 mg) for 5 days beginning 2 days after the second GnRH treatment. Cloprostenol was given on the last day of FSH, the donors were bred 2 days later, embryos were collected 7 days after breeding. In recipients (n = 8), the second dose of GnRH was given the day before donor mating, and embryos were transferred on the day of donor collection. On average (± SEM), 5.2 ± 1.4 corpora lutea were detected and 2.5 ± 1.2 transferable embryos were collected in the donors. A mature corpus luteum was detected in 6/8 synchronized recipients and a single embryo was transferred to each. One recipient alpaca became pregnant and delivered a healthy baby 349 days after embryo transfer. This is the first report of successful embryo transfer in alpacas in Canada.

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.
