La buserelina en programas de superovulación para transferencia de embriones
Bibliographic record
Abstract
Resumen El objetivo de éste trabajo fue comparar la respuesta superovulatoria y la cantidad y calidad de embriones recuperados en vacas Holstein en la Sabana de Bogotá, mediante la aplicación de buserelina en el día 6 del ciclo estral, antes de iniciar el esquema de superovulación . El trabajo se realizó en la Sabana de Bogotá, a 2640 msnm y una temperatura promedio de 12° C. Se emplearon veinte bovinos hembra de la raza Holstein a los cuales se les aplicó FSH (Vetrepharm Inc, Ontario,Canadá) para inducir superovulación, en los dias 11, 12 13 y 14 del ciclo estral, con una dosis total de 20 cc, y PGF 2ª (Pharmacia & Upjohn, Kalamazoo, MI, USA) con la última dosis de FSH, 3 cc im. A diez de ellas (grupo tratamiento) se les aplicó Buserelina (Hoechst Roussel Vet, München, Alemania) en el día 6 del ciclo estral, antes de iniciar el tratamiento superovulatorio. Las diez vacas restantes se consideraron como grupo control. Los resultados obtenidos muestran que hubo diferencia significativa entre el grupo tratamiento y el grupo control respecto a la respuesta superovulatoria (p < 0,05) No se encontró diferencia significativa en el número de embriones recuperados en ambos grupos (p > 0,05). Palabras clave: análogos de GnRH, folículo dominante, superovulación, vaca. Summary The aim of this work was to compare the superovulatory response and the quantity and quality of recovered embryos in Holstein cows at the Sabana de Bogotá, through the application of buserelin at day 6 of the oestrus cycle, before starting the superovulatory treatment. The work was performed at the Sabana de Bogotá, at 2640 mosl, with an average temperature of 12 °C. 20 female bovines of Holstein breed were injected with FSH (Vetrepharm Inc, Ontario, Canada) to induce superovulation at days 11,12,13,and 14 of oestrus cycle, using a total dose of 20 cc per cow, and 3 cc of PGF2a (Pharmacia & Upjohn, Kalamazoo, MI, USA) with the last dose of FSH. Ten cows (treatment group) received buserelin (Hoechst Roussel Vet, München, Alemania) on day 6 of estrous cycle, before starting superovulatroy treatment. The remaining ten cows were considered as control group. The results show significative difference between treatment and control group regarding superovulatory response (p < 0,05). It was not found a significative difference between treatment and control group regarding the number of recovered embryos (p > 0,05). Key words: dominant follicle, GnRH analog, superovulation, cow.

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.
