Comparison of effects of <i>Isotricha</i> monofauna and total mixed fauna on dietary copper metabolism in lambs
Bibliographic record
Abstract
Three groups of 15 fauna-free (FF) lambs each were used to establish the effects of Isotricha sp. (IS) monofauna on the dietary copper (Cu) solubility in the stomach and on the concentration of Cu in the liver. One group remained FF (control) while the second and third groups were inoculated with IS and total mixed fauna (TF), respectively. All lambs were fed ad libitum a corn silage based diet for 168 d. Thereafter, the lambs were killed and livers, kidneys and stomachs were removed and sampled. Different fauna treatments did not affect (P > 0.1) growth performance parameters. In comparison with the FF sheep, both the TF and IS decreased (P < 0.05) the rumen solubility of Cu, but the decrease by IS (23%) was approximately half of that of TF (41%; P < 0.05). Similarly, TF and IS decreased the liver Cu concentration by 15% (P < 0.1) and 7.5% (P > 0.1), respectively. Although TF that significantly decreased the bioavailability of dietary Cu included IS and Dasytricha species, it appears that an absence of these Holotrich protozoa from the rumen protozoa population would not have a significant effect on the efficiency of the population to alleviate chronic copper toxicity in sheep. Key words: Isotricha, rumen, ciliate protozoa, lambs, copper

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.
