Technical Abstract: The objective of this study was to evaluate compliance of US producers with the proposed BTSCC limits. Four different SCC levels of compliance were evaluated: 750K; 600K; 500K; 400K. For the 12 month period ending October 2010, 1.0% of producers and 0.2% of milk exceeded the current US limit of 750K; 4.7% of producers and 1.4% of milk exceeded the proposed 600K limit; 11.0% of producers and 3.8% of milk would have exceeded the proposed 500K limit; and 23.3% of producers and 10.1% of milk would have exceeded the 400K limit. Seasonal variations in the BTSCC reveal that July through October are the months where the percent of producers and milk above the proposed limit are higher than the yearly average. For herds shipping <907 metric tons of milk in the 12 month period, 28.0% would have exceeded the proposed 400K US limit. Only 4.1% of herds shipping more than 9,072 metric tons would have exceeded the proposed 400K US limit. If implemented, the proposed phased in reduction to a 400K BTSCC limit would result in a substantial increase in producers and milk which would exceed the regulatory limit, primarily from herds with <100 cows.
