Abstract

fetched live from OpenAlex

During summer months, elevated barn temperature reduces pig growth rate by decreasing feed intake. Two trialswere conducted over two summers to evaluate the effect of reduced nocturnal temperature on the performance and carcassquality of growingfinishing pigs. Control rooms had a typical temperature setpoint while the temperature setpoint fortreatment rooms was 6C lower. In Saskatchewan, a reduced temperature setpoint resulted in a lower nocturnal roomtemperature (1.6 o C cooler over eight weeks), while it had no influence on room daytime temperature. The average dailytemperature fluctuation in treatment rooms was increased by 2.1 o C. The lower nocturnal temperature also resulted in a higherrelative humidity (+3%) and lower CO2 and NH3 concentrations. During trial 1, pig average daily gain (ADG) in thetreatment room was increased by 5.2%. For trial 2, feed intake was 3.2% higher in treatment rooms, which increased ADGby 2.1% on average over eight weeks. The ADG increase averaged 3.6% during the last four weeks of trial 2. However, nostatistical differences were found for pig performance, feed conversion, and backfat thickness (P > 0.05). The results suggestthat healthy pigs are not negatively affected by a large daily temperature fluctuation (up to 14.8C) as long as this fluctuationis progressively achieved.

Teacher imitation

Not 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.
