• reduced risk of residues in milk
• reduced risk of the presence of human pathogens and their toxic products in the milk supply
• greater profits to producers through decreased herd level of mastitis
Adopting the rolling geometric mean calculation for herd SCC would provide producers with a valuable management statistic and would lead to increased international harmonization of standards as nearly all major dairy producing countries use the geometric mean calculation. The geometric mean is the mathematically correct statistic to use for averaging SCC data.
A 400,000 cell/ml limit is achievable by our industry, Ruegg states. “The US dairy industry has tremendously educated and innovative producers who have the knowledge and ability to achieve this limit. Most milk is already below this limit and there are ample resources available to help transition producers to the new limit, assuming that sufficient time is available for the producers to adapt. This is the reason that the NMC proposed a gradual phase-in of the new limit, reaching 400,000 cells/ml in 2014.”
This is also a tremendous opportunity for dairy veterinarians to work with their producers on milk quality. “Analysis of data from our seven years of experience with milk quality teams really demonstrated the positive milk quality impact that veterinarians and producers can make when they work together with common milk quality goals,” Ruegg says.
