Yeah it has been a HUGE loss. Luckily only 4 were heifers. Something fishy is going on though.... I do artificial insemination for my cows and do not buy sexed semen (like girl or boy semen) because it is just too expensive (About 150 a vial and takes about 4 vials to impregnate!) so I buy straight run semen but out of 36 calves only 8 were heifers. Something is not right..... I have a bull now so all calves starting june 8th are from my own bull....
Why not let the cows do it themselves why do you have to inject them??
