Net energy content of dry extruded-expelled soybean meal fed to growing pigs using indirect calorimetry
Bibliographic record
Abstract
Feed is the single most expensive input in commercial pork production and at least 50% of this cost can be attributed in supplying energy to the animal thus making energy financially the most vital component. Swine diets can be formulated on a variety of energy systems such as the digestible energy (DE), the metabolizable energy (ME) and the net energy (NE) systems of which the NE system provides more accurate estimates of the energy available to the animal. Energy values of protein-rich feeds are often overestimated when expressed on a DE or ME system (Noblet et al., 1994). These discrepancies in measurement of available dietary energy have a drastic effect on the economics of pig production and there is, therefore, an ongoing interest in adopting the NE system. The most commonly used protein source in livestock diets is soybean meal (SBM), but it also contains certain antinutritional factors which depress animal growth performance. Studies show that such antinutritional factors are reduced significantly during meal processing (Perilla et al., 1997). One such process is the combination of extrusion with expelling which produces a SBM product called dry extruded-expelled SBM (DESBM). However, published data pertaining to the energy values of DESBM for grower pigs are limited. The aim of this study was to determine the NE content of DESBM in growing pigs using either an indirect calorimetry (IC) or published prediction equations.

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.
