Signs and Symptoms

Symptoms

Bovine leukemia virus is a chronic, lymphoproliferative disease in which infected cattle may develop:

  • Increased lymphocyte count (lymphocytosis)
  • Higher prevalence of other infections resulting in mastitis, lameness, etc.
  • Tumors.

In some cases, cattle may be asymptomatic despite being infected with BLV.
