Bovine myiasis is a condition caused by the infestation of cattle by certain species of flies, particularly blowflies and screwworms. These flies lay their eggs on the skin or in wounds of the cattle, and when the larvae hatch, they burrow into the flesh, causing tissue damage and infection. This condition can lead to serious health issues for the affected animals, including pain, weight loss, and even death if not treated promptly. Control measures include proper hygiene, wound care, and the use of insecticides to prevent fly infestations in cattle populations.
