Dose-dependent inhibitory effects of an investigational feed additive containing bromoform on methane emissions from cattle fed fresh pasture.

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
Bromoform, a bioactive compound in certain seaweeds, has gained attention for its methane-mitigating effects in ruminants. Research is underway to use synthetic bromoform as an alternative for providing consistent and predictable dosing of the bioactive compound, but its inherent volatility and liquid form limit its application. To address these challenges, an investigational feed additive (IFA) in the form of a powder containing synthetic bromoform has been developed by Rumin8 Pty Ltd., West Perth, WA, Australia. The objective of this study was to evaluate the effect of the Rumin8 IFA on methane emissions from cattle fed fresh pasture. Sixteen 18-month-old Hereford × Friesian heifers (427 ± 11 kg; mean ± SD) were stratified by weight and randomly allocated to control and treatment groups using a randomised block design. Treatments included IFA doses at 100, 300, or 500 mg/d of bromoform per heifer, plus a placebo control. The heifers were fed fresh pasture twice daily with a total feed allowance set at a level of 1.6 to 1.8 times their maintenance energy requirements with 800 g of dried distiller's grain pellets containing treatments or placebo before each meal. After 16 d, the heifers' methane emissions were measured in open-circuit respiration chambers for 48 h. The results showed that pasture-fed heifers produced less methane when treated with the bromoform-containing IFA at every dose level (
