Formula
Sum (Total Weaning Weight)
--------------------------------------
TotalWeaned Piglets
Where:
Sum: sum of total weaning weight from each sow in the period
TotalWeaning Weight: Total weight of piglets at weaning from each sow in the period (consider partial and total weaning of this sow);
ATTENTION!!!
The counted weaners are related to the sows for total weaning in the period. However, before full weaning, this sow may have had partial weanings inside or outside the period, and they must also be included (as long as these partial weanings are from the same lactation cycle as the full weaning).
