Dairy Herd Management summarized my breakout session talk at the Four-State Dairy Nutrition & Management Conference in Dubuque, Iowa on June 14, 2018. Many factors affect twinning in dairy cows, but milk production and progesterone at the beginning of timed AI protocols that include a second prostaglandin treatment are two primary factors.

Read about our latest research in the latest issue of Dairy Herd Management on why about 20% of nonpregnant cows don’t return to estrus between AI and pregnancy diagnosis conducted 32 d after AI.

I had the opportunity to speak for the May, 2016 Hoard’s Dairyman webinar series. The video of the webinar is linked on my web site here:

I made the cover of the May/June issue of Bovine Veterinarian magazine. Looks like we can have high milk production AND high fertility in lactating dairy cows.

The 2016 Four-State Dairy Nutrition and Management Seminar will be held on June 15-16 at the Grand River Center in Dubuque, IA. The final brochure of the program including a registration form can be downloaded here. I will be presenting on Thursday morning.

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.

I had the opportunity to address the dairy practitioners attending the American Association of Bovine Practitioners annual meeting in New Orleans, LA on Saturday, September 19. The title of my talk was: “Double Vision: Management of Twinning in Dairy Cows.” I have uploaded a draft of my proceedings paper as well as a pdf of my slides under the Extension tab on this site.
