Effects of Qiamagu (Brassica rapa L.) polysaccharide on growth performance, immunity and gut health of yellow-feathered broilers.
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 5 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
This study aimed to investigate the effects of adding Qiamagu polysaccharides to feed on the growth performance, immunity and gut health of yellow-feathered broilers. A total of 240 healthy, day-old, male yellow-feathered broiler chickens with similar body weights were randomly divided into four groups, each with six replicates and 10 chickens per replicate. The groups consisted of a control group (CON) and three treatment groups: TP1 (250 mg/kg), TP2 (500 mg/kg), and TP3 (1000 mg/kg) of Qiamagu polysaccharide in the diet, with a feeding period of 64 days. The average daily weight gain of all experimental groups were significantly higher than those of the CON group (P < 0.05) in 1-21 days. The average daily gain of TP1 and TP2 groups was increased (P < 0.05), and the ratio of feed to gain was decreased (P < 0.05), at 43-63 days. The levels of IgM, IgA, IgG, IL-1β, IL-2 and TNF-α in the serum of broilers in the TP1 and TP2 groups exhibited a consistent increase at 21,42 and 63 day (P < 0.05). At 22-42 days, the villus length of duodenum and ileum and the ratio of Villus height to crypt depth ratio were increased in TP2 group (P < 0.05). The ileal mucosa IL-1β and IL-2 mRNA levels of broilers in TP3 group were down-regulated in 1-42 days (P < 0.05). The mRNA levels of MUC2, ZO-1 and Occluding in ileum mucosa of broilers in TP3 group were up-regulated in 1-63days (P < 0.05). The total number of cecal flora species in TP1, TP2 and TP3 groups was higher than that in control group (P < 0.05). The relative abundance of Lactobacillus in TP2 group was increased (P < 0.05). In conclusion, this study showed that the addition of Qiamagu polysaccharide improved the growth performance, enhanced the immune response and had better impact on intestinal health of yellow-feathered broilers.
