Evaluating the effects of adaptation length, dietary electrolyte balance, and energy source on ileal endogenous amino acid losses in pigs fed nitrogen-free diets
Bibliographic record
Abstract
Sixteen cannulated pigs were used to evaluate the effect of dietary electrolyte balance (DEB, low vs. high), energy source (cornstarch vs. dextrose), and adaptation length (3–4 or 6–7 d) to the diets on basal ileal endogenous amino acid (EAA) losses in pigs fed nitrogen-free diets (NFD) in a randomized complete block design with a 2 × 2 × 2 factorial arrangement of treatments. Each of the two phases lasted 7 d with a 12 h digesta collection on days 3, 4, 6, and 7. Pigs received a daily feed allowance of 4% of their body weight. There was no significant three-way interaction. Longer adaptation length increased (P < 0.05) ileal endogenous losses of N, arginine (Arg), glycine (Gly), proline (Pro), and total amino acid (AA). Dextrose-based NFD resulted in higher (P < 0.05) ileal dry matter digestibility and EAA losses (13 of 18 AAs) compared with pigs fed cornstarch-based NFD. High DEB resulted in a decrease (P < 0.05) in endogenous threonine, cysteine, Gly, and serine losses. The two-way interaction between energy source and DEB was significant for N, total AA, and five AAs with a combination of dextrose and low DEB resulting in higher (P < 0.05) losses. Results from this study show that NFD could be fed for a shorter period of time (3–4 d) with results that are comparable to a 7 d adaptation period except for N, Arg, Gly, and Pro.

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.
