    Should you be giving a second PG injection on day 8 after giving it on day 7?

    Seems to be the advice at the moment, it used to be 1 shot the day before CIDR removal and same day for heifers but been tweaked it seems for better conception rates

    Very interested to hear how you get on
    Just 1 shot & CIDR here with mixed results
