Addition of Equex STM to Extender Improves Post-Thawing Longevity of Collared Peccaries' Sperm
Bibliographic record
Abstract
paste supplementation on the Tris-extender for collared peccaries' semen cryopreservation was assessed. Semen from 12 mature individuals was obtained by electroejaculation and evaluated for morphology, membrane integrity, osmotic response, and sperm kinetic metrics. Samples were diluted in Tris plus 20% egg yolk and divided into three aliquots. The first aliquot was without any supplementation, the second and third contained 0.5 and 1.0% Equex STM, respectively. The samples were added with 3% glycerol, frozen in liquid nitrogen, thawed, and assessed for the same parameters after a thermal resistance test (TRT) for 120 minutes. Similar values were detected for the different treatments immediately after thawing, except for the amplitude lateral head that was reduced in samples containing Equex (p < 0.05). During TRT, samples containing Equex were more efficient in preserving the sperm motility (at 0.5%: 25.5% ± 4.4%; at 1%: 33.3% ± 6.3%) at 30 minutes, in comparison with the control group (16.6% ± 6.0%), in which sperm motility decreased at 15 minutes (p < 0.05). Moreover, Equex, especially at 0.5% concentration, was able to maintain plasma membrane integrity and sperm motility in all the samples after incubation for 60 minutes. In conclusion, we recommend the addition of Equex STM at 0.5% to the Tris-extender to improve post-thawing sperm longevity in collared peccaries.

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; a candidate call from one teacher head, not a consensus.
