Heifer Antibiotic Use and E. Coli Resistance on 37 Dairy Farms

A cohort of heifers on 37 farms in South West England was followed from birth to 18 months or first pregnancy. Faecal environmental samples were collected over 2 years and analyzed for E. coli resistance to amoxicillin, cefalexin, and tetracycline, with results presented as binary detection. Farm-level antibiotic usage data is also included.

Use Cases

• Analyze the binary detection of amoxicillin-resistant E. coli strains against farm-level antibiotic usage data to assess treatment impact.
• Model the relationship between cefalexin and tetracycline resistance outcomes in heifers using longitudinal farm management data.
• Investigate patterns of antibiotic-resistant E. coli presence in faecal samples across the 37-farm cohort over the 2-year study period.

Strengths

• Data covers 37 dairy farms, providing a multi-farm cohort for analysis.
• Longitudinal design tracks heifers from birth to 18 months or first pregnancy.
• Includes binary results for E. coli resistance to three specific antibiotics: amoxicillin, cefalexin, and tetracycline.

Limitations

• Sample size and number of rows are unknown, limiting assessment of statistical power.
• Column names and data structure are unspecified, requiring exploration upon download.
• Data is from a specific region (South West England) and may not generalize to other geographies.
