Apparent digestibility comparison in rainbow trout (<i>Oncorhynchus mykiss</i>) assessed using three methods of faeces collection and three digestibility markers
Bibliographic record
Abstract
Experiments were undertaken to investigate the apparent digestibility coefficient (ADC) of a range of macro- and micronutrients in rainbow trout using three external digestibility markers (chromic oxide, acid insoluble ash and titanium dioxide, alone or in combination), and three methods of faeces collection (modified Guelph system, St-Pee system and abdominal massage; hereafter referred to as ‘column’, ’collect’ and ‘strip’, respectively). For each method of faeces collection, three replicate tanks of fish were acclimated for 5 days to a practical diet containing the external marker followed by 5 days of faeces collection. Both marker type and collection method significantly influenced ADC estimate in a similar manner for dry matter, protein, nitrogen-free extract, ash and energy. The ADC was consistently highest for the column and lowest for the strip methods of collection, and titanium dioxide gave higher ADCs vs. the other markers. Lipid ADC did not differ between the column and collect methods, but collection of faeces by the strip method gave lower ADCs, irrespective of marker type. In general, nutrient ADC was higher with the combined markers than when single markers were employed. The influence of marker type and collection method was less clear for the individual minerals studied.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
