Laying Hen Performance Data on Probiotic-Enzyme Supplementation in Low-Protein Diets

A 10-week study of 720 Hy-Line Brown laying hens aged 45 weeks, evaluating the impact of a probiotic-enzyme complex on laying performance and gut health. The dataset, authored by Qiuchen Liu and last updated in 2026, compares three dietary groups: high-protein, low-protein, and low-protein with supplement. Results include egg production rate, feed conversion ratio, eggshell strength, and gut microbiota changes.

Use Cases

• Compare egg production rates and feed conversion ratios between dietary groups based on the described experimental results.
• Analyze the relationship between intestinal health metrics (e.g., villus height) and laying performance based on the study description.
• Investigate correlations between serum metabolite levels and the abundance of beneficial bacteria like Lactobacillus and Bacillus as mentioned in the description.
• Model the mitigating effects of dietary supplements on the adverse outcomes of low-protein diets in poultry.

Strengths

• Experimental design includes a substantial sample size of 720 hens across three defined treatment groups.
• Study duration of 10 weeks provides a clear temporal scope for longitudinal analysis.
• Results include specific, statistically significant findings (p < 0.05) for key metrics like egg production and feed conversion ratio.

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 relatively small at 1.3 MB, potentially limiting the complexity of analyses.
