Effects of Low-Protein Diets with Enzymes on Lactating Sows and Offspring Performance

A Chinese study involving 40 multiparous sows investigates the effects of low-protein diversified diets supplemented with compound enzymes on swine nutrition and health. The dataset, authored by Xuewen Bi and last updated in April 2026, includes results on sow performance, nutrient digestibility, serum biochemistry, and fecal microbiota in offspring. The research employed a 2x2 factorial design comparing conventional and diversified diets with and without enzyme supplementation.

Use Cases

• Modeling the relationship between diet composition and sow reproductive performance based on measured weaning-to-estrus intervals.
• Analyzing the impact of enzyme supplementation on nutrient digestibility based on crude protein apparent total tract digestibility results.
• Investigating correlations between maternal diet and offspring gut microbiota based on fecal microbiome analysis data.
• Studying nitrogen utilization efficiency in livestock based on serum urea nitrogen and growth hormone concentration measurements.

Strengths

• Experimental data from a controlled 2x2 factorial design involving 40 multiparous sows.
• Includes multiple outcome measures: performance, digestibility, serum biochemistry, and fecal microbiota.
• Specific performance metrics are reported, such as a weaning-to-estrus interval of 4.5 days for the LDD+E group.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 2.9 MB, potentially limiting the scope of analysis.
