Animals: Gap Calculator

DairyNZ’s SmartSAMM Gap Calculator helps you assess the economic benefit of achieving your mastitis performance targets.   

The economic benefit is achieved through closing the ‘gap’ between your herd’s actual, and target performance, through:

  • Increased milk sales, as cows with lower SCC produce more milk;
  • Lower costs & losses due to less clinical mastitis;
  • Less culling and deaths related to mastitis.

The gap calculation makes no allowance for the marginal costs of achieving the goal or target performance, which will be unique to every individual herd and situation.

Two versions are available, depending on your needs. 

 

A. SmartSAMM Gap Calculator - Simple paper version

To use:

  1. Print off a blank copy
  2. Fill in the spaces
  3. Complete calculations as directed. View Sample for a completed calculation
  4. Seek advice to interpret the results and develop a plan of action for closing the gap.

Note - this calculator provides the same somatic cell count gap as the Basic Gap Calculator, in the electronic version.

However clinical mastitis and cull calculations are made as simple as possible.

For more detailed estimates go to the electronic version.
