Don't buy calves through an auction mart. You'll be buying yourself a heap of trouble. Chances are they will have had no colostrum.
Eek - That's harsh!!! We've bought thousands of baby calves through our local markets with no more trouble than the calves bought direct... Any problems are likely more related to the stress of markets and the exposure to bugs from other calves.
At least if you buy direct from local dairy farmer you'll perhaps have some support if you need any advice on rearing... Where in country are you?
Or alternatively there are increasing numbers of 'calf groups' around the country who supply rearers direct from farms or via collection centres, again, reducing the stress of being pushed aound a market...
Good luck!
