Effects of time of feeding during gestation on sow's performance1.
Article in Journal of animal science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The aim of this study was to investigate the effect of different feeding time regimes given similar energy intake per kilogram live BW0.75 during gestation on sow's performance. One hundred and seventy-four sows [Topigs TN 70 (Landrace × Large White, Topigs USA); parity 3.81 ± 0.16; initial BW = 211.57 ± 3.34 kg; backfat (BF) 13.70 ± 0.42 mm] were blocked by parity, farrowing date, balanced for BW and randomly assigned to 1 of 3 treatments in a randomized complete block design. Treatments included sows fed corn-soybean meal-based diet once at [0730 (control, T1), 1130 (T2), or 1530 h (T3)], with daily feed quantity kept at 1.25× maintenance energy intake [100 × (BW)0.75] kcal ME/d. Sows received 6,758, 7,434, and 8,110 kcal ME/d from days 30 to 60, days 61 to 90, days 91 to 109 of gestation, respectively. The gestation diet was formulated to contain 3,379 kcal of ME/kg, 0.70% Ca, 0.61% total P, 0.58% SID Lys, 0.26% SID Met, 0.45% SID Thr, 0.12% SID Trp, and 0.48% SID Met+Cys. Body weight and BF were recorded on days 30, 60, 90, and 109 of gestation, 24 h after farrowing and at weaning. Results showed that feeding times evaluated did not alter BW changes from day 30 to day 109 of gestation (P = 0.81) or from day 30 to weaning (P = 0.87). Similarly, feeding sows daily at 1130 h did not influence BF gains and sow reproductive performance relative to the control sows (P > 0.10). Sows fed once daily at 1530 h gained more BF compared with the control (3.69 ± 0.47 vs. 2.12 ± 0.50 mm, P = 0.04) from day 30 to day 109 of gestation. From day 30 of gestation to weaning, treatments did not influence BF gain (P = 0.24). Feeding sows daily meal at 1530 h had propensity to increase (P = 0.09) the number of piglets weaned by 0.54 piglets compared with the control sows. In conclusion, the present study demonstrated that feeding pregnant sows at 1530 h altered energy and nutrient metabolism improving their BF gain and exhibited a potential to increase the number of weaned piglets compared with conventional feeding regime.
