The impact of antemortem nutrition in beef cattle on carcass yield and quality grade
Bibliographic record
Abstract
Three thousand and thirty-six crossbred steers and heifers averaging 570 ± 7.1 kg were used in the present study to test the efficacy of providing antemortem nutrition for 12 to 24 h pre-slaughter on carcass yield, grade and meat quality. All cattle were transported for up to 6 h prior to being held overnight at one of three midwestern USA abattoir sites. While at the abattoir, the cattle were randomly assigned to one of three treatments: control (offered water only 12 to 24 h pre-slaughter, which is industry standard practice); placebo (offered 2 kg per head of a rice hull-corn-based pelleted feed for 12 to 24 h pre-slaughter plus ad libitum water); or nutritional therapy (offered 2 kg of an energy/amino acid/electrolyte product plus ad libitum water for 12 to 24 h pre-slaughter). The cattle offered antemortem nutritional therapy displayed a 20% or greater retention of quality grade score (P < 0.01) and a significant reduction in dark-firm-dry beef (P < 0.05) compared with either the placebo or control animals. In addition, animals receiving nutritional therapy treatment had a greater retention of carcass weight (≥ 2 kg, P < 0.05) compared with control cattle. Data from the present study suggest that the use of antemortem nutrition, especially for overnight-held cattle, may be effective in reducing carcass loss and quality grade reduction.

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.
