Impact of yam bean pulp on growth performance, gut morphology, digestive development, and digestibility in broilers raised in hot environments.
Article in Animal bioscience, 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
objectiveRearing broilers in high-temperature environments can impair growth performance, affecting the economic efficiency of broiler production. Dietary fiber sources like yam bean pulp (YBP) may mitigate these effects by promoting digestive organ development and gut integrity, enhancing nutrient absorption and growth. This study aimed to evaluate the impact of YBP inclusion on digestive development, gut morphology, nutrient digestibility, serum lipid profiles, and growth performance in broilers raised under high environmental temperatures.
methodsSince YBP has not previously been used in poultry diets, its optimal inclusion level was determined using in vitro digestibility measurements, which identified 4% YBP as the optimal initial inclusion level for further in vivo study. Subsequently, the in vivo study was conducted with 200 one-day-old ROSS broiler chicks, randomly assigned to four dietary treatments (0%, 4%, 8%, and 12% YBP; 5 replicates of 10 birds each), and housed in an open system at an average temperature of 32.1±3.7°C. Digestive traits, nutrient digestibility, serum lipid profiles, and growth performance were assessed over 21 days.
resultsResults showed that YBP inclusion (up to 12%) improved gut morphology by increasing villi height and the villi height-to-crypt depth ratio in the duodenum and ileum, alongside dose-dependent improvements in dry matter digestibility. However, crude protein digestibility declined when YBP levels exceeded 8%. Despite these benefits, YBP inclusion did not alleviate heat stress effects on growth performance, digestive organ development, or serum lipid profiles, even at the highest inclusion level.
conclusionDietary YBP can enhance gut morphology and nutrient digestibility in broilers from day 1 to 21, with optimal inclusion levels not exceeding 8%. However, its use does not mitigate the negative effects of heat stress on broiler growth in high-temperature environments.
