Freeze-dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs.
Article in Journal of the science of food and agriculture, 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
backgroundDirect fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the effect of controlled feeding of a freeze-dried, DFM comprising Lactobacillus spp. (providing 1 × 10
resultsThe average daily liveweight gain (ADG) was 24% greater (P = 0.009) and the total body condition score change from the start to the end of the experiment was 28% greater (P = 0.019) for lambs supplemented with freeze-dried Lactobacillus spp. (FDL) compared to the control lambs (CON). Average methane production (g methane per day) tended to be lower (P = 0.095) and methane intensity (g methane g
conclusionThis experiment showed that FDL supplementation to growing lambs on a hay-based diet improved liveweight gain and lowered methane intensity over a 70-day feeding period. © 2026 The Author(s).
