7. Countdown Objectives
97% of annual average herd bulk milk cell counts (BMCC) below 400,000 cells/ml, (the 400,000 cells/ml threshold relates directly to the EU directive EEC 92/45 on milk quality);
70% of herd BMCC below 250,000 cells/ml;
90% of farmers can access resource to effectively manage raw milk microflora, and; Chemical residue risks are lessened and result in no loss of market access.

8. Defining the pathogen BM

22. Simple Machine Checks
Teat scoring immediately after the unit is removed
Pulsation. Examine for oedema of teats or place your finger in the liner and check for a throbbing feeling
Vacuum reserve. Leak air through a milking unit for 5 seconds, record the fall in vacuum. Vacuum recovery time should be less than 3 seconds. Also if vacuum drops by more than 2kPa with 20%(1 out of 5) units leaking air, this is unacceptable.
Vacuum Regulator. Leak air into units to reduce the plant vacuum by 5kPa. The regulator should stop leaking air to restore the vacuum, without overshooting.
Check liners for cracks, deposits and age
