Buying cows - check mastitis records and examine udders
In this guideline:
21.1 Buy heifers before first calving (rather than cows), where possible
21.2 Don’t buy cows unless bulk milk SCC and mastitis records are available
21.3 Check cows' udders before buying them, and again before milking them
21.4 Milk introduced cows last until you are confident that they are free of mastitis
21.5 Don't milk other people's cows with your herd
