Verrat Piétrain Francisco

One year ago, in the news of the 12 of January 2015, we showed the first results of feed efficiency of Pietrain boars controlled with feeding station control situated directly on the selection farm.

One year later, these first results are confirmed and even improved.

With an average feed efficiency of 2,17 during the period 30kg - 115 kg, the NUCLEUS Pietrain Boar is a guarantee to improve your global efficiency and thus your production cost!

Intra-muscular fat measurement on live animal

Cochette Duroc 2016

NUCLEUS started in 2015 to measure the intra-muscular fat content in its entire pure breed Duroc population, gilts and boars.


This measure is done at the same time that on farm testing, it means at five months old. Thus, in Duroc criteria measured on farm are now:


Muscle depth

Backfat thickness

Intra-muscular fat on loin


This measure of intra-muscular fat on live animal enables NUCLEUS to identify and to select for specific markets breeders having the highest intra-muscular fat content.


NUCLEUS : to meet your request.
