Type of evidence:
Peer-reviewed conference contribution (scientific committee) — National Mastitis Council (NMC) 49th Annual Meeting
Participating institutions:
Multi-institutional collaboration (Università degli Studi di Milano; Dairy Decisions, LLC; Arizona State University) as reported in the contribution
Sector:
Dairy cattle — environmental hygiene (cubicles with mats)
Experimental design:
Comparison of treated vs. control area; biweekly microbiological sampling
Sample:
40 cows (2 groups of 20)
Sampling period:
February – June 2009 (biweekly)
Main outcomes:
Total bacterial load and microbiological indicators (streptococci, coliforms/Enterobacteriaceae, E. coli)
Main results:
−36.9% TBC (treated vs. control)−47.5% streptococci (treated vs. control)−48.71% Enterobacteriaceae/coliforms (treated vs. control)−30.80% E. coli (treated vs. control)Significance reported: P < 0.05Context note:
Barn surface hygiene is a measurable and repeatable operational lever, useful for reducing environmental microbial pressure.
Methodological and compliance note
The reported results derive from a peer-reviewed conference contribution and describe microbiological monitoring evidence under real farm conditions. The evidence should be interpreted in the context of the study design and the conditions reported in the contribution; it does not replace health or management assessments on the farm. The cited SOP products are not veterinary medicinal products and are not intended for the treatment, prevention, or cure of diseases. Health-related decisions remain the responsibility of the attending veterinarian, in compliance with regulations and good farming practices.
