Overview Merck Bovilis Piliguard Pinkeye-1 Trivalent is a season-long, single-injection pinkeye vaccine for cattle, providing protection against three piliated strains of Moraxella bovis — EPP63, FLA64, and SAH38. Infectious bovine keratoconjunctivitis (IBK / pinkeye) is one of the most economically damaging diseases in beef cattle, causing significant weight loss, reduced performance, and costly treatment programs. The oil-emulsion formula is designed to deliver durable, season-long immunity from a single 2 mL injection administered 3–6 weeks before peak pinkeye season — making it a practical, low-labor prevention tool for cow-calf and stocker operations. The 100 mL bottle contains 50 doses for herd-level vaccination programs.
