Effects of dietary metabolizable energy and crude protein levels on laying performance, egg quality and fecal microbiota of Taihe Silky Fowl during the peak laying period.
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 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
objectiveThe experiment aimed to study the effect of dietary metabolizable energy (ME) and crude protein (CP) on laying performance, egg quality, serum routine biochemical and lipid metabolism indicators, the apparent digestibility of nutrients, and fecal microbiota of Taihe Silky Fowl (TSF) during the peak laying period.
methodsA total of 540 26-week-old TSF female fowls were randomly allocated to 9 groups with 5 replicates per group and 12 fowls per replicate. The fowls were fed with a 3×3 factorial arrangement of treatments diets (ME:10.88,11.30, or 11.72 MJ/kg; CP: 15, 16, or 17%).
resultsWith the increasing CP level, the egg weight (p = 0.023), egg production (p = 0.047), and egg mass (p = 0.022) enhanced, while the feed conversion rate (FCR) (p = 0.023) decreased. As the ME levels grew, the average daily feed intake (p<0.001) and FCR (p = 0.045) decreased. With enhanced ME, the triglycerides (p = 0.037), total cholesterol (p = 0.041), and high-density lipoprotein cholesterol (p = 0.028) increased, whereas the low-density serum lipoprotein cholesterol (p = 0.039) decreased. The apparent digestibility of CP increased as the ME level increased (p = 0.029) and as the CP level decreased (p = 0.027). At the same time, the apparent digestibility of gross energy increased as the ME level increased (p = 0.018). Different levels of ME or CP changed the composition of fecal microbiota, 17% CP increased the abundance of Bifidobacterium.
conclusionIt is suggested that 10.88 MJ/kg dietary ME and 17% CP level are suitable for the nutritional requirements of TSF during the peak laying period.
