Determinants of carcass traits and pricing in crossbred beef cattle under a cooperative production system in tropical Thailand.
Article in Animal bioscience, 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
objectiveQuantitative evidence linking carcass traits to pricing under cooperative beef production systems in tropical regions is still scarce. This study aimed to identify the biological and management determinants of carcass traits and their economic implications in crossbred beef cattle raised under a cooperative system in tropical Thailand.
methodsThe carcass and pricing records from 5,531 crossbred finished cattle (3,109 steers and 2,422 females) across six breed groups and 217 farms were examined. Fixed effects in general linear models were farm-year-season (FYS), breed group, sex, and physiological maturity (number of permanent incisors; teeth). Marbling score (MS) and cover fat thickness (COVF) were additionally fitted for pricing traits.
resultsCarcass and pricing traits were strongly influenced by FYS, breed group, sex, Teeth, MS, and COVF (p<0.001). Each additional pair of teeth increased live weight (+15.28 kg) and cold carcass weight (+7.93 kg) but reduced price per carcass weight (-0.53 THB/kg). MS was the strongest economic driver; a one-unit increase increased carcass price by 12.34 THB/kg and live value by 5,889 THB/head. COVF had positive but smaller effects. Charolais crossbreds exhibited the highest carcass mass, Wagyu had crossbreds the greatest marbling, and Brahman crossbreds had the highest dressing percentage.
conclusionCarcass value is driven by two pathways: carcass mass determines total return, and marbling drives price premiums, providing a biologically grounded framework for optimizing breed selection, management, and slaughter strategies in tropical cooperative systems.
