Guidelines For Purchasing
Cows and Heifers
Mastitis, BVD, sterility, poor milk production, and beha
vioral problems are just a few of the concerns when purchas
ing cows or heifers. Reasons for purchasing cows or heifers
can affect the health of new additions. Purchasing cows or
heifers as a result of ongoing health problems in the herd
will likely affect the health of new animals.
Health problems should be solved before bringing new an
imals onto the premises. Dairy producers purchasing
springing heifers or cows to expand the herd, or purchasing
younger replacements, should take the time to search for
animals based on criteria that increase the likelihood of suc-
cess.
The following check list should help you determine which
animals are right for your herd.
