Amino acid digestibility in six sources of meat and bone meal, blood meal, and soybean meal fed to growing pigs
Bibliographic record
Abstract
Standardized ileal digestibility (SID) of amino acids (AAs) by growing pigs was determined in blood meal and six sources of meat and bone meal (MBM). Eighteen ileal-cannulated barrows (initial body weight: 69.3 ± 4.4 kg) were randomly allotted to a replicated 4 × 9 incomplete Latin square design with four periods and nine diets, giving eight replications per diet. One diet included 33% soybean meal (SBM) as the sole source of AA. Seven diets contained 9% blood meal or 9% of one of the six sources of MBM and 22% SBM as the only AA containing ingredients. The last diet was a nitrogen (N) free diet. Results indicated that the SID of all AAs were different (P < 0.05) among the six sources of MBM, but the SID of lysine (Lys) could not be predicted from the ratio between Lys and crude protein. For some, but not all AAs, the average SID in MBM was greater (P < 0.05) than in blood meal, but for most AAs the SID in MBM was less (P < 0.05) than in SBM. It is concluded that, as is the case for most other co-products, differences in concentration and SID of AAs among sources of MBM exist.

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.
