I would think that would be doable...
You'd have to address the different vaccum pressures, pulsation rates and ratios, etc.
But as far as design... I would probably just do it as a dbl sided with each side dedicated for the type of animal.
I milked into buckets for my first two years... no problem.
I believe I have the original sketch of my dairy that is a pdf file...
I'm not very knowledable about this forum yet, so I'm not sure about attachments.
I'll play with the attachment feature and see if I can attach it.
What state/country are you in? Are you planning to license? that could make a difference...
How many of each type of animal do you plan to milk?
Are you going to use stachions or crowd? I have crowd plans that are very inexpensive using galvanized pipe.
Keep in mind this is dairying on a budget... nothing facncy... but passes regs.
