Yes. They have a pretty small herd. He breeds the cows so they'll start calving in January, then moves his bull to the heifers.Were your neighbours just using the one bull TC? I guess people get complacent but even if you didn't test in situations like that it is not that hard to write down cow numbers and dates of when the bull is wining and dining a lady and then check again in 3 weeks to make sure there is no more romance.

I check at least once a day after I turn out the bulls and note which cows they're either breeding or glued to their side (not in standing heat yet). Dates and which bull bred which cow is entered in my spreadsheet and, using the gestation calculator, potential due date. The exception is when it's a 2-fer and I'm not sure which bull actually bred the cow until she calves. I can tell right away as soon as I see the calf.
