Effects of maternal feeding of clofibrate on hepatic fatty acid metabolism in suckling piglet.

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
backgroundEnergy deficiency is a leading cause of the high pre-weaning mortality of neonatal piglets in the swine industry. Thus, optimal energy metabolism is of crucial importance for improving the survivability of neonatal piglets. The effective utilization of milk fat as primary energy is indispensably required.
methodsPregnant sows (n = 27) were randomly assigned into 3 treatments. Each treatment received a standard diet (3,265 kcal ME/kg) supplemented with either 0, 0.25% or 0.5% clofibrate (w/w) from d 107 of gestation to d 7 of lactation. The effects of maternal clofibrate on their milk fatty acid (FA) and performance of the piglets were evaluated. The evaluations were performed via measuring sow productive performance, milk FA composition, and hepatic FA oxidation of the piglets at birth and d 1, 7, 14 and 19 after birth.
resultsMaternal supplementation of clofibrate had no effect on reproductive performance of the sows at farrowing and weaning (P > 0.05). However, the mortality at weaning was reduced for piglets from sows with 0.25% of clofibrate, and the average weekly (and daily) gain was higher in piglets from sows that received clofibrate than sows without clofibrate in the first week (P < 0.0001). Maternal clofibrate increased percentage of milk C12:0 and C14:0 FAs but decreased C18:2 and n-6 polyunsaturated FAs. Maternal clofibrate also increased plasma ketone body levels and hepatic FA oxidation measured at the first day of birth, but the increase was not detected in piglets on d 7, 14 or 19. Clofibrate was not detected in milk collected from the clofibrate-treated sows. The percentage of FA oxidation decreased, and the percentage of FA esterification increased with increasing in postnatal age. Supplemental carnitine increased FA oxidation regardless of succinate dehydrogenase inhibition, and the increase had no effect on FA esterification.
conclusionsMaternal supplementation of clofibrate during late gestation and early lactation increases hepatic FA oxidative metabolism at birth and improves growth performance of newborn piglets. Maternal clofibrate transfer to suckling piglets via milk was not detected. Carnitine availability is critical for piglets to maintain a high FA oxidation rate during the suckling period.
