Formula






         Total IBWM

--------------------------

Total mated sow with IBWM


 




Where:


Total IBWM: sum of the IBWM of all analyzed sows.

Total mated sow with IBWM: total number of sows that weans from previous cycle and is now mating with IBWM






Considerations:

For the sow farm, consider the period as the interval of days between the sow entry in the farm until today's date.


Pay attention to the mating of lactating sow. In this case, as the mating occurs before weaning, the IBWM will be equal to zero.
