Effects of pelleted timothy hay on pair-housed Holstein calf performance.
Article in Journal of animal science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This randomized control trial evaluated the effects of feeding pelleted hay to paired dairy calves on body weight (BW), average daily gain (ADG), calf starter dry matter intake (DMI), and solid feed efficiency (FE) up to one week after weaning (75 d of age; mean ± SD). Holstein heifer calves (n = 32 pairs; 64 calves) were enrolled at pairing (5 ± 3 d of age; referred to hereafter as day 0 of the study) and randomly assigned in blocks of four pairs to a control (CON; no hay) or treatment (HAY; timothy hay). All calves received 7.4 L/d of milk replacer (MR; 22% crude protein [CP], 20% fat) until 56 d, 3.2 L/d from day 57 to 62, and were weaned on day 63. The HAY group had a trough with pellets until day 59, then they were transitioned to long-stem timothy hay until study completion on day 70 (7 d postweaning). Starter and hay intake and refusals were recorded daily. We measured BW twice weekly until 30 d, then weekly, and a final BW was recorded on day 70. We calculated the average pair starter DMI, solid FE, ADG, and BW by period where period 1 = birth to day 26, period 2 = day 27 to 60, period 3 = day 61 to 67, and period 4 = day 68 to day 75 ± 3 d of age. We used mixed linear regression models to assess the impact of HAY, period, and the HAY × period interaction on ADG, BW, solid FE, and starter DMI, adjusting for birthweight, season, serum total protein, and period with period as a repeated measure, calf as the subject and pair nested within block as a random effect. We used Tukey adjustments to correct for multiple mean comparisons. There was no association of HAY with ADG (CON; 0.88 ± 0.03 vs. HAY; 0.88 ± 0.03 kg/d), starter DMI (CON 2.68 ± 0.15 vs. HAY 2.50 ± 0.14 kg/d), or solid FE (CON 0.65 ± 0.07 vs. HAY 0.73 ± 0.07). We suggest that pelleted timothy hay offered to paired calves warrants further research on behavior and health outcomes, and it does not impact calf starter intake, BW, or average daily gains.
