I firmly believe that people just accept lame cows they dont realise the cost of lameness.it is one of the real advantage of channel island cattle is there feet and not being lame.when we were fr, hardly ever picked a foot up, usually, stone or foul, as we got more and more holstien, I had to do a course, on foot trimming, there is a whole industry based on trimming cows feet, I think that answers many questions. Its quite interesting to look back through bull pedigrees, and proofs,.. and see the negative for feet, in some of the really famous bulls. The purists would say, pli gets updated etc, so not relevant, but, the bad feet continue, and perhaps increase, to be a serious problem, if they were bad 30/40 years ago, and still bad today, something isn't quite right. We used holstien, because they were 'better', and now we are looking back. Uncle, with his channel island herd, went from having the vet, to the odd lame cow, and progressing through, to all hols, having a trimmer in, every 2 weeks.
