Research in the laboratory of Dr. Christopher A. Price, Centre de Recherche en Reproduction Animale (CRRA), Université de Montréal, has identified unusual antigrowth functions of a growth factor in the ovary.

Over the last 5 decades, the worldwide dairy industry has made significant gains in milk production and milk quality by genetic selection, however, these gains have led to a major problem: a significant decline in fertility. It was reported that the average herd 21-day pregnancy rate in Canadian dairy cattle is around 14% (Ambrose & Colazo, 2011).
