N FLA | Recommendation is 28 days+. I had a few cows I kept, that by the time they calved, must have only been 14 or so days bred at sampling. I'm sure they have reliability at 28 days, margin for error at somewhat less than that.
I liked it. I fell like I can sample on April 15, and know a cow was or was not bred by March 15th. Maybe in reality I know she was/not bred by April 1st. Either way works for me. | |
