Table 1_Probiotic-enzyme complex improves laying performance in laying hens fed low-protei

Qiuchen Liu's dataset contains results from a 10-week experiment evaluating a probiotic-enzyme complex (PEC) in 720 Hy-Line Brown laying hens. The data includes measurements of egg production, feed conversion ratio, eggshell strength, jejunal villus morphology, serum metabolites, and gut microbiota composition. The dataset was last updated on 2026-05-29 and is shared under a CC-BY-4.0 license.

Use Cases

• Compare egg production rates and feed conversion ratios based on dietary protein levels and probiotic supplementation.
• Analyze correlations between gut microbiota composition (e.g., Lactobacillus, Bacillus abundance) and host metabolic pathways like arginine biosynthesis.
• Model the relationship between intestinal health metrics (villus height, crypt depth) and eggshell quality parameters.
• Evaluate the mitigating effects of a specific probiotic-enzyme complex on the performance of hens fed a low-protein diet.

Strengths

• Experimental design includes 720 hens across three treatment groups with six replicates each, providing a basis for statistical analysis.
• The 10-week study duration allows for observation of medium-term effects on laying performance and health.
• Measures multiple outcome types: production metrics, egg quality, intestinal morphology, serum metabolites, and microbiota.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical methods.
• The dataset is small (1.3 MB), which may indicate it contains summary results rather than raw observational records.
