To the men of my life ...
– to my dad, Jacques, for his wonderful and unrelenting support throughout my years as
a graduate student. Without him, I wouldn’t be where I am now.
– to my dear husband Roger, for encouraging me and sharing his enthusiasm for this
project every step of the way. Without him, I may never have started this book.
– to my son Vincent, for believing in his mother’s dream and for representing the
continuity in all things just as this book will allow dissemination of information on sow
lactation for generations to come.
I love you and I thank you ...
