A dataset from a controlled feeding trial with 60 periparturient cows investigating the effects of four different protein sources. It includes measurements of rumen fermentation parameters, microbial composition, serum indicators, nutrient digestibility, nitrogen utilization, and differential metabolites in feces and urine. The dataset was authored by Yaqiong Ren and last updated on 2026-06-03.
Use Cases
- Compare the impact of rapeseed, linseed, sunflower, and soybean meal on rumen microbial communities based on the described enrichment of bacteria like Fibrobacter and Akkermansia.
- Analyze metabolic pathway enrichment in fecal and urinary metabolites, such as steroid synthesis or amino acid metabolism, across different dietary treatments.
- Model relationships between protein source, serum indicators like insulin and growth hormone, and immune response parameters described in the results.
- Investigate nitrogen utilization efficiency and blood ammonia levels in periparturient cows fed different protein supplements.
Strengths
- Data originates from a controlled experiment with 60 cows divided into four treatment groups of 15, providing a structured comparison.
- Includes multi-modal measurements: rumen parameters, microbial data, serum indicators, nutrient digestibility, and metabolomic profiles from feces and urine.
- Released under a permissive CC-BY-4.0 license, allowing for broad reuse and sharing.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for specific modeling tasks.
- The dataset is relatively small at 2.7 MB, potentially limiting the complexity of analyses.
