Evaluation of zootechnical parameters of piglets born and suckled from dams treated with a non-steroidal anti-inflammatory drug after farrowing
Bibliographic record
Abstract
Background: Farrowing is a precarious moment in pig production potentially associated with a wide range of ailments in sows and gilts, and often having a negative impact on pre-weaned piglet zootechnical performances. Aim: To evaluate zootechnical parameters of piglets born and suckled from dams treated postpartum with tolfenamic acid at a commercial farm. Methods: Dams were randomised to receive an intramuscular injection of 4% tolfenamic acid at 2 mg/kg body weight within 12 hours postpartum (TA group) or no inflammatory treatment (control group). Evaluated parameters included individual piglet live weight at birth (day 0); number of live piglets at day 2; mortality at weaning; and individual weight at weaning. IgG transfer assessment was conducted in a subset of piglets stratified by suckling position. Results: 81 dams and their litters were included (TA group: 20 sows, 21 gilts, 472 piglets; Control group: 20 sows, 20 gilts, 458 piglets), with IgG transfer assessment conducted in 80 piglets of 20 randomly selected dams (TA group: 40; Control group: 40). Piglet performances in the TA versus control groups respectively, were: average daily gain 0.23 ± 0.06 versus 0.20 ± 0.06 kg (p<0.05); weaned weight 6.32 ± 1.23 versus 5.50 ± 1.09 kg (p<0.05); day 1 plasma IgG levels in piglets from gilts were 20.60 ± 3.78 versus 16.99 ± 4.23 µg/ml (p<0.05); and mortality at weaning was 6.6% (31/472) versus 11.8% (54/458) (p<0.05). The within-litter weaned weight variation in the TA group was not significant (p=0.11) at 6.50 ± 1.11 kg in the anterior suckling position versus 6.76 ± 1.01 kg in the posterior teat suckling positions, while the difference was significant (p<0.05) in the control group, at 5.61 ± 0.68 kg versus 5.37 ± 0.75 kg, respectively. Conclusions: Piglets in the TA group had statistically significant improved zootechnical performances, while their within-litter weaned weights did not differ significantly.

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.
