Quality of chilled indigenous ram semen using skim milk-based extenders
Bibliographic record
Abstract
This study aimed to evaluate the effects of extenders using skim milk from different species on sperm quality during storage at 5°C over time. Eight ejaculates were preserved in each of five home-made semen extenders: cow skimmed milk (CSM), goat skimmed milk (GSM), sheep skimmed milk (SSM), buffalo skimmed milk (BSM) and commercial dried skim milk (CDSM). Sperm motility, plasma membrane integrity, and normal morphology (%) were assessed at 0, 24, 48, 72, 96, and 120 hours. At 48, 72, 96, and 120 hours, sperm motility in the GSM extender was higher than in the BSM, SSM, and CDSM extenders. Plasma membrane integrity (%) and normal sperm morphology (%) in the GSM and CSM extenders were significantly higher than in the BSM, SSM, and CDSM extenders at 24, 48, 72, 96 and 120 hours. Overall, motility, membrane integrity, and normal morphology were superior in the GSM extender. Further research is needed to validate sperm quality in relation to lambing rates. Bang. vet. 2025.

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.
