Jun 8, 2021

mySYNCH by Parnell has grown to a community of over 1.3 million dairy cows across the U.S.! 

We have analyzed the latest data to publish our second mySYNCH Fertility Report. The Top 10% of mySYNCH herds by Pregnancy Rate achieve a 35% Pregnancy Rate and are far outpacing the average herds. Additionally, since our first report, there have been some notable changes in the practices of the top herds.
