The boar is bred from the TOPIGS P-line (a Pietrain line). The Top Pi sire is very lean and has a very high meat percentage. The boar is completely stress-free, which means that its progeny are vigorous. Top Pi carcasses show low drip losses. The qualities of the Top Pi boar progeny are:
- very high meat percentage
- muscularity and very good conformation
- stress-free, so low drip loss and strong piglets
- low feed conversion rate
