Infectious bovine keratoconjunctivitis 2019
Most cases of morbidity were observed among under one-year old animals
shown on the table 1. This is probably because young animals do not have so effective
immune system and they do not have previous exposure with this disease (Takele and
Zerihun, 2000).
