Bovine Leukosis Virus

Is your herd infected with BLV?
The first step in preventing the spread of BLV in your herd is to know whether or not your cows are infected. Simply send a blood or milk sample to Northwest Labs to be tested.

Bovine Leukosis Virus is spread by blood. The virus can be transferred by contaminated needles, dehorners and taggers, as well as rectal palpation sleeves and calving pull chains. Be sure to disinfect equipment between animals and use sleeves and needles just once.

To maintain a BLV-free herd, remember to test each animal you buy before exposing her to your other livestock.
