Abstract
The aim of this work was to evaluate in situ degradability of dry matter (DM), crude protein (CP), organic matter (OM) and cell wall (M) of three grasses from genus Cynodon: Tifton 44 (Cynodon dactylon (L) Pers) (T44), Tifton 85 (Cynodon spp) (T85), Estrela do Porto Rico (Cynodon nlemfuensis Vanderyst (L) Pers) (PR), with 400kg N/ha or without nitrogen application in three cows with rumen fistulas. Four cuts were performed at a 35-day interval at approximately 10cm from the soil surface. Incubation time consisted of 6, 12, 24, 48 and 96 hours respectively. Degradability rate (c) did not differ between grasses and nitrogen applications. The effective degradability of DM (EDDM) and OM (EDOM) was not affected by nitrogen applications. PR and T44 EDDM, estimated through 5%/h passage rate, was higher than that of T85, though PR potentially digestible fraction (b) was the smallest. T85 had the smallest values for crude protein effective degradability (CPED) and this same grass had the largest values for fraction “b” of CP. The grasses did not differ for effective degradability from cell wall (EDCW) at 5%/h and 8%/h. T44 showed statistical difference (p≤0,05) in response to nitrogen application. T44 and T85 grasses had larger fraction values than PR.

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 it
