Abstract
Rodríguez, D. A., Sulabo, R. C., González-Vega, J. C. and Stein, H. H. 2013. Energy concentration and phosphorus digestibility in canola, cottonseed, and sunflower products fed to growing pigs. Can. J. Anim. Sci. 93: 493–503. Many protein sources are available to the swine feed industry, but accurate data for the energy concentration and the standardized total tract digestibility (STTD) of P in these ingredients are lacking. Therefore, two experiments were conducted to determine the concentration of digestible energy (DE), metabolizable energy (ME) and the STTD of P in oilseed products. In exp. 1, 48 barrows (44.8±3.9 kg) were fed a basal diet containing 97.15% corn or seven diets containing corn and canola seed (CS), canola meal (CM), cottonseed meal (CSM), sunflower seed (SFS), sunflower meal (SFM), de-hulled sunflower meal (SFM-DH), or soybean meal (SBM). Six pigs were allotted to each treatment. Sunflower seeds contained 5492 kcal kg −1 , at least 689 kcal kg −1 more (P<0.05) ME than all other feed ingredients. Likewise, CS (4803 kcal kg −1 ) had greater (P<0.05) ME than SBM (3676 kcal kg −1 ), and both CS and SBM had greater (P<0.05) ME than CM, SFM, SFM-DH, and CSM (2998, 2725, 2631, and 2459 kcal kg −1 , respectively). In exp. 2, 84 barrows (13.7±1.5 kg) were allotted to 14 diets, which contained each of the oilseed products without or with phytase, in a randomized complete block design with six pigs per dietary treatment. The STTD of P in SBM was at least 4 percentage units greater (P<0.05) than the STTD of P in the other ingredients. Adding phytase to the diets reduced fecal output of P from all ingredients and increased (P<0.05) the STTD of P for all ingredients except SFM-DH. The ME concentration in SFS and CS is greater than that of SBM and the STTD of P among these ingredients is comparable, which indicates that SFS and CS may be fed to growing pigs at the expense of SBM.

How this classification was reachedexpand
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.
