Wat is the origin of your farm ?

My parents always had a few sows. My father had acquired the Piétrain sow, Gatée de Castelain, who was born in 1956. I built my breeding from her descendants.

How many sows do you have right now ?

My breeding is consisted by 40 sows, essentially Piétrain positive but a part of my livestock is devoted to the stress-resistant Piétrain.

What is the main goal in your selection ?

I select my animals on their growth rate. For me, a Piétrain must have a minimum of 600 g a day growth rate.

What are the other points of attention in your farm ?

I pay attention to the sanitary level of my breeding. This is essential to be able to sell boars at insemination centers. My livestock is free from PRRS and I want it to remain so.

I also try to eliminate the defects as much as possible. I never keep a breeder out of a nest including pives or herniated. The number of teats is not primordial for me to produce boars that will be used in a terminal cross.

I also participate actively to the testing program set up by the AWE. Since the introduction of cross-breeding genetic assessments in 2007, I have placed more than 100 boars in the program. This tool is essential for me to carry out the selection work in my breeding.

What is your greatest pride as a pig breeder ?

My greatest pride is undoubtedly the age of my lineage because the founding sow of my breeding is born in 1956. I am also quite proud of the evolution that I have realized on the speed of growth and I intend to continue to evolve it.

I am very happy to produce Piétrain that stand out by being completely black and who mark their descendants. It is not uncommon to see black piglets crossing from my boars.
