Feed alleys are feed alleys, calfs born and in barn, tied to walls are NOT a piss/*censored* fest. Keep close to mom, so mom milks easier, calfs *censored*/pee mothers milk. Beddind is Dried sawdust absorbs more water/pee/ *censored* than you believe, after 3 weeks they go to pens, calves in pens move to heifer barn. iMilks tested every pickup... no problems. So whats your problem? Machines did what you wouldn't do, and put your DAIRY farm out of business, to costly? Uep, everyone has a way of doing... some cost wise effective, others... you got to do this to be produce safe milk. Test at pick up tells the sanitary story, not how you use keep calfs, to heifers, to freshened, to grave lifes sanitary. Yes more labor involved cleaning barn... but production is good, and what you think is S/P in feeder lane isn't. Cows maybe DUMB, but none will eat. *censored* or Pee! So windyhill... go back to your great NON farming hill! Oh its 80 milkers, everyday, plus 80 heifers in heifer barn, about half bred, and about 10 4 month old calves in pens, ones tied to walls are about 2 days to 2 weeks old.
