1 · What the graph read from it

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.

2 · The registry

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 study evaluated growth performance, carcass characteristics, and meat quality of pure Menz sheep, and 50% Dorper × Menz (D×M) and 50% Awassi × Menz (A×M) crosses under two feeding regimes: brewery spent grain plus concentrate (F1) or concentrate-only (F2) used as supplement with natural pasture hay as basal diet. The supplemental feeds were isonitrogenous and isocaloric. Forty-eight castrated yearling rams (16 per genotype) were assigned to the dietary treatments in a 2 × 3 factorial design and the experiment lasted for a period of 90 days. Data on nutrient intake, body weight changes, carcass measurements, and sensory scores were taken and analyzed using the standard procedures. Breed significantly (p < 0.05) influenced final body weight, average daily gain, and carcass traits, with DxM and AxM outperforming Menz sheep. F2 yielded greater feed conversion efficiency than F1 (p < 0.05), while digestibility coefficients did not differ among the treatments (p > 0.05). DxM sheep had higher cold carcass weight, loin cut weight, and fat thickness (p < 0.01), and dressing percentage was greater in F2. Sensory evaluation showed that meat from Menz sheep was preferred from tenderness, juiciness, flavor, and overall acceptability (p < 0.01) compared to other sheep breeds. Significant breed × feed interactions for sensory attributes indicated genotype-specific dietary response. Strong positive correlations (r = 0.72–0.95, p < 0.01) between growth and carcass yield highlight the predictive value of performance traits for meat output. Based on marginal rate of return and superior carcass yield, A×M sheep are strongly recommended under both brewery spent grain plus concentrate (F1) and concentrate-only (F2) feeding regimes, while D×M sheep are recommended under the F1 feeding regime.
