STOCKTON — “Pinkeye reduces calf weight gain, cow milk production, calf sale price and increases treatment costs which negatively impact profitability of a cattle operation,” University of Missouri Extension Livestock Field Specialist Patrick Davis said.
Reduction of cattle herd pinkeye potentially improves cattle operation performance and profitability.
Cattle pinkeye potential increases with the fly season beginning.
“The main culprit bacteria that causes pinkeye is Moraxella bovis,” Davis said.
However, eye irritation is important for the invasion of the bacterium leading to pinkeye.
“Face flies irritate the eye and transmit the bacteria that causes pink eye so methods to control these flies should reduce the incidence of pinkeye,” Davis said.
He urges cattle producers to utilize the best fly control method for their operation.
Some methods include backrubbers, dust bags, insecticide tags and strips, sprays, insecticides and oral larvicides.
“Reduction of eye irritants like plant material and dust will reduce the incidence of pinkeye,” Davis said.
