There are many ways to manage, calculate and analyze the cost of milking labor. For example....
Assuming one Milker can indeed operate a dbl. 12 by him or herself, milking at the rate of 90 cows/hr for seven hours. You'd be milking some 600 to 650 cows 3x with a crew of 4 milkers, including a full time relief milker. The milkers work 9 hrs, with the 9th hour being the first hour for the next shift.
You were fortunate to find good people and you are paying well, like $30,000 or $35,000/yr for some $120,000 to $150,000 per year of total milking payroll.
You'll need twice that many milkers to milk the same 600 cows through a parallel with rope or chain detachers. Twice the training, twice the management headaches and twice the annual payroll.
Now look at the future..and assume that the efforts to keep illegal immigrants out of the country will be moderately successful. Skilled milkers will be increasingly hard to find and those who are skilled will be increasingly aware of their worth, their value to you. ..
What are the chances that thousands of young Americans - the high school students in your very town - will go back to milking cows? Zip! Their buddies are going to college, into the military or at least into a community college. Milking cows? Slaughtering chickens? Mucking manure? Hardly. How'd the girls look at them?
It'll cost you for those who do - immigrants, and fewer of them. The time will come when your decision to milk with Arm TakeOffs will look pretty darn good.
