The combined effects of extended feeding with a high level of Arthrospira platensis and a commercial enzyme mix or porcine pancreatin on broilers' blood cells, plasma metabolites and liver lipid profile.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe increasing global demand for sustainable and eco-friendly protein alternatives in poultry production has led to the exploitation of unconventional feed ingredients, such as microalgae. This study is novel for its exploration of the extended feeding effects (from day 7 to day 35) of a high inclusion level (15%) of Arthrospira platensis (Spirulina) in broiler chickens' diet, either alone or supplemented with enzymes, primarily peptidases (EC 3.4). The study assessed the impact on the blood cells, metabolic status and the hepatic content of lipids, pigments and minerals. One hundred and twenty Ross 308 male chickens were distributed into 40 battery brooders, housing three birds per cage. Initially, the chickens were given ad libitum access to a standard corn and soybean meal-based diet for the first seven days. Subsequently, from day 7 to 35, they were assigned to one of four experimental diets: a control diet based on corn and soybean (control group, n = 10), a diet incorporating 15% A. platensis (SP group, n = 10), a diet incorporating 15% A. platensis supplemented with 0.025% of the commercial enzyme mix VemoZyme
resultsThe 15% inclusion of A. platensis negatively impacted the birds' growth performance by decreasing the final body weight (p < 0.001), body weight gain (p < 0.001) and average daily feed intake (p < 0.001), while increasing the feed conversion ratio (p = 0.001). This high level of A. platensis incorporation did not change the haematological profile but raised blood lipid levels. However, these increases were successfully normalized by supplementing the diet with the enzyme mix VemoZyme
conclusionsOverall, data suggest that the impact of A. platensis on blood and liver measurements outweighs the effect of enzyme supplements, VemoZyme
