In situ degradability of genus Cynodon grasses with or without nitrogen application
Bibliographic record
Abstract
Avaliou-se a degradabilidade in situ da matéria seca (MS), proteína bruta (PB), matéria orgânica (MO) e parede celular (PC) de três gramíneas do gênero Cynodon: Tifton 44 (Cynodon dactylon (L) Pers) (T44), Tifton 85 (Cynodon spp) (T85), Estrela de Porto Rico (Cynodon nlemfuensis Vanderyst (L) Pers) (PR), com (400kg N/ha) ou sem adubação, utilizando-se 3 vacas com fístulas ruminais. Foram realizados 4 cortes a cada 35 dias, com um nível de, aproximadamente, 10cm do nível do solo. O tempo de incubação foi de 6, 12, 24, 48 e 96 horas. A taxa de degradação (c) não diferiu entre as gramíneas e na aplicação de nitrogênio. As degradabilidades efetivas da MS (DEMS) e MO (DEMO) não diferiram para o nível de nitrogênio aplicado. A DEMS, estimada com a taxa de passagem de 5%/h, da PR e da T44 foi superior à da T85. A fração potencialmente degradável (b) da PR porém, foi de menor valor. A T85 apresentou os menores valores para a digestibilidade efetiva da proteína bruta (DEPB), mas registrou o maior valor para a fração “b”. As gramíneas não diferiram para a digestibilidade efetiva da parede celular (DEPC) a 5 e 8%/h. A T44 obteve diferença estatística (p≤0,05) em resposta à aplicação de nitrogênio. As gramíneas T44 e T85 foram superiores à PR em relação à fração “b”.

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.
