An article I wrote entitled “Timing is Everything in Pregnancy Diagnosis” has been published in the October 25, 2015 issue of Hoard’s Dairyman. The article describes results from a recent research trial in which we assessed factors affecting levels of pregnancy-associated glycoproteins in blood and milk during early pregnancy and their implications for nonpregnancy diagnosis in dairy cows.

Let me know what you think!
