I didn't read the links yet, so forgive me if I repeat something...
Â
Testing:
vaccinated for Brucellosis
tested for TB, Johnes (not all do - it's not required)
tested for BLV and Q-fever - optional
Milk - tested for the usual (SCC, coliform, etc)
Â
Feeding:
How many cows/acres?
24/7 access to pasture, or only some parts of the year? (you'd be surprised, in the larger dairies, how many keep their cows in when the grass is nice, since they don't want everything trampled, or for water/stream-health regs).Â
How much grain per cow? What type?
What type of hay? Silage?
Â
Milking:
Hand or machine milk? Definitely ask to watch during milking, if you can.
How long have they been milking, and selling milk?
How long does their milk keep?
How is the milk processed (filtered, chilled)?
How is the equipment cleaned?
Â
Any disease issues in the herd, ever? Mastitis? Mastitis pops up at some point in virtually every herd - it happens - but ask how they treat it.
Where did their cows come from? Be very afraid(!) of any auction cows or "rescues".
Â
Really, the best measure of a farm is whether it leaves you with a good impression after visiting - happy, clean cows, a farmer who knows and cares for his animals, meticulous milking and cleaning habits, etc.Â
Â
Let me know what ideas I should expand on!Â
I've been hand-milking Jersey cows since 2003, and I've visited many dairy farms over the years - both conventional and raw.
