Influence of feeding thermally peroxidized lipids on the performance of growing pigs.
Article in Journal of animal science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Feeding pigs lipids containing high levels of lipid oxidation products (LOP) has been shown to reduce growth performance, but data is lacking on quantitative relationships between LOP and pig growth, feed intake, and feed efficiency. Four experiments (EXP) were conducted using soybean oil (SO) in EXP 1, 2, and 3, as well as SO, choice white grease and palm oil (PO) in EXP 4, to evaluate the impact of feeding diets containing different amounts of LOP on pig performance. Lipid peroxidation was carried out using variable heating temperatures and durations to generate lipids with a broad range of peroxide (PV, mEq) and anisidine value (AnV, unitless). Lipids were added to the diets at 10%, 10%, 8%, and 7.5% for EXP 1, 2, 3, and 4, respectively, with dietary PV and AnV calculated using lipid peroxidation concentrations of PV and AnV times the dietary lipid inclusion rate. Within each experiment, pig performance (6.2 to 13.4 kg, EXP 1; 13.5 to 23.7 kg, EXP 2; 20.3 to 36.9 kg, EXP 3; 29.6 to 44.1 kg, EXP 4) was affected differently depending on dietary PV and AnV concentrations. Using the control-fed pigs within each experiment as a baseline of 100%, correlations of pooled relative pig performance data (dependent variables of ADG, ADFI, and GF) from EXP 1, 2, 3, and 4 with their respective dietary LOP values (independent variables of dietary PV and AnV due their ability to be measured commercially) resulted in significant (P ≤ 0.01) regression equations for relative ADG [ADG, % = 101.2 - [(0.321 × PV) + (1.019 × AnV)], R2 = 0.81], ADFI [ADFI, % = 100.8 - [(0.320 × PV) + (0.629 × AnV)], R2 = 0.68], and GF [GF, % = 101.3 - [(0.016 × PV) + (0.525 × AnV)], R2 = 0.70], albeit PV was not a significant regression coefficient in the GF model (P = 0.90). This data shows that the values of primary and secondary LOP (i.e., PV and AnV, respectively) could be effectively used in predicting the effect of feeding oxidized lipids on growth, feed intake, and feed efficiency in growing pigs.
