N FLA | Blood test is easy. So far, results look extremely reliable here. It seems a 75 day season is going to have some negatives, and that could be one. Maybe you would be ahead to leave the bull in 120 days and sell the late calving ones the following year if that would be easier economically or emotionally, and still weed out for high fertility.
That is kind of what I do in the context of these old cows here. Although I do expect 25% open in a 90 day window. I blood test to detect who got bred in that 90 day window and who didn't. | |
