wow that's really cool!! a lot of technological stuff!!! we just built a new parallel milking parlor in the fall...holds 12 on each side it's very nice....however it was **** the first week gettin our cows to switch from a heiringbone to parallel...from personal experience sand bedding is the best..that is what we use now...we just started to use it in the summer in our new stall barn. this winter we converted our old barn to all sand as well. the sand has definately cut back the number of cows with mastitis and ecoli. we we up to 30 before we converted our old barn into sand. now we are down to only 4!!! we have done every kind of bedding...started with straw, then to dry wall chips, then to saw dust, now to sand and by far sand has been the best!
