Infectious Bovine Keratoconjunctivitis (IBK) is a problematic recurring disease for cow-calf producers. The IBK lesions have been associated with a 7-14 kg decrease in weaning weight compared with calves with no recognized IBK lesions.

Preventive practices recommended are often impractical and there is little evidence that vaccines are effective
