216 Effect of Spray Dried Plasma on the Standardized Ileal Digestibility of Crude Protein and Amino Acids in Diets Based on Different Ingredient Combinations Fed to Young Pigs
Bibliographic record
Abstract
Abstract An experiment was conducted to test the hypothesis that spray dried plasma (SDP) increases the standardized ileal digestibility (SID) of CP and AA from other ingredients in diets for young pigs, which may result in a lack of additivity in such diets. Thirty ileal cannulated barrows (body weight: 9.30 ± 0.63 kg) were randomly allotted to a triplicated 10 × 3 Youden square design with 10 diets and three 7-d periods. Diets from four regions were formulated: the U.S.A. [corn-soybean meal (SBM)-based diet], the European Union (corn-wheat-barley-SBM-based diet), Canada (wheat-barley-SBM-fermented SBM-based diet), and Asia (corn-rice-SBM-fermented SBM-based diet). Diets from each region contained 0 or 6% SDP. Differences between measured and predicted SID of CP and AA in diets with SDP were calculated. Data were analyzed using PROC MIXED of SAS as a 2 × 4 factorial with 2 levels of SDP and 4 regions. There was an SDP by region interaction for the measured SID of CP and all AA, except Lys (Table 1). When SDP was added to the U.S.A, the European Union, and Asia diets, the SID of CP and AA was not increased. The SID of CP and AA, except Lys, was greater (P < 0.05) in the Canada diet with SDP than without SDP. The measured SID of CP and AA was consistent with predicted values for the European Union and Asia diets (Table 2). The measured SID of Trp was less (P < 0.05) than predicted for the U.S.A. diet, and the measured SID of CP and all indispensable AA was greater (P < 0.05) than predicted in the Canada diet. In conclusion, addition of 6% SDP to wheat-barley-based diets may increase SID of CP and AA, and therefore, the SID of CP and AA in diets containing SDP may be greater than predicted.

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.
