Mum said also the sucking action makes the womb contract which hurts apparently, this is all why I said on a thread the other day that I can forgive a suckler especially a heifer for being reluctant to stand let her calf suck, most times we have found that the heifer is fine the next year anywaywas thinking this last night about this thread and the other thread about heifers not letting calves suck, most people on here wont have breast fed either, its bloody painful to start with till you get desensitised, and also when they are full of milk it hurts worse, so saying why dont they want the calve to relieve it , its not like that, you have to grit your teeth and your eyes water for the first 5 mins so its the same for cows.
