Hello Dr. Giordano, thank you for presenting this interesting study.
Do you recall what was the proportion of cows (by parity) that had a “silent ovulation” (confirmed ovulation with no signs of estrus)?
Thank you
Hi Tony, thanks for the question. The overall proportion of cows with a silent ovulation ~6.5%. I defined silent ovulation to calculate this number, as a cow not being detected by the reference test in our study and with confirmed ovulation by TUS and P4.
I’d have to go back and calculate by parity. I hope this helps.
Best regards,
Julio
