i dont have time to read all the posts here but i wanted to let all know, we raise a dairy steer every other year ( get as bottle babies and butcher when they weigh around 900lbs)
we have 2 freezers, (soon to be 3) it used to be one for beef, one for chicken . but we also started raising a hog a year too so now we will have one for pork.
we feed our steers horse quality alfalfa hay . 60 days before butcher we feed a all organic grain to help with a few extra pounds. i believe that home grown meat is better, beef inparticular, that is raised in feedlots are fed a lot of corn (because its cheap) cattle cant process it well, so they form bacteria in their gut that in turn can make us sick.
we have raised both full dairy steers and half angus half holstien steers, i never have noticed a difference. around here, a dairy bull that is 2 days old  to a week old will cost only 40$ but a angus bull at the same age will cost a few hundred.
my 2 daughters (6 years old and 4) know that their are animals here that get butcherd and some that dont.  as of yet, we havent had a attachment problem, i think its about being open and honest about what that ' cute little calf ' is for. we started out by telling the girls that they are for eating and now they ask when we go pick them up lol
i hope that you can give raising your own beef a try!!  its so awesome to cook dinner with everything  grown or raised at home! 
oh by the way, call around and find out how much per pound butchering is. it will also be very helpful!
good luck!
