Effect of dietary metallo-protease and Bacillus velezensis CE 100 supplementations on growth performance, footpad dermatitis and manure odor in broiler chickens.
Article in Animal bioscience, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveThis study focused on the effect of dietary metallo-protease and Bacillus velezensis CE 100 on growth performance, carcass parameters, intestinal microflora, footpad dermatitis (FPD), and manure odor in broiler chickens.
methodsOne hundred-ten (two-day-old Ross 308) broiler chicks were randomly assigned to five groups with two replicate pens. The dietary treatments were divided to control, metallo-protease groups (A1, added with 0.1%; A2, added with 0.2%) and B. velezensis CE 100 groups (B1, added with 0.5%; B2, added with 1.0%).
resultsThe feed intake was decreased in A1 and B2 compared to the other group (p<0.05). The liver weight was lower in B2 than in A2 (p<0.05). The Salmonella in the cecum was decreased in A2 compared to control and A1 (p<0.05). However, the lactic acid bacteria were increased in all treatments (p<0.05). The litter moisture content was decreased in A2, B1, and B2 (p<0.05). The litter quality visual score was increased in all treatments (p<0.05). The FPD score and prevalence were reduced in all treatments (p<0.05). The (CH3)2S emission was decreased in all treatments (p<0.05).
conclusionThe present study indicated that both additives improve litter quality and reduce the incidence of FPD. These findings suggest that dietary metallo-protease and B. velezensis CE 100 have the potential to improve the broiler chickens' welfare.
