Incidence of lameness requiring veterinary treatment in dairy cattle in Queensland.
A survey of the incidence of lesions causing lameness in dairy cattle was conducted by veterinarians in 9 practices in Queensland between November 1984 and July 1985. One hundred and eighty five cases were treated in 83 dairy herds. The average incidence of lameness which required treatment by veterinarians was 2.7 cases per 100 cows per 9 months, with a range of 1.4 to 5.5% in the 9 practices. Foot lesions constituted 83.2% of all lesions; the most common being interdigital necrobacillosis (15%), deep sepsis (8.9%), white line disease (8.4 per cent), axial groove fissure (8.4%), bruised sole (5.6%) and foreign body in the sole/heel (5.6%). Sixty-five per cent of foot lesions occurred in the hind feet and 63% of these lesions occurred in the lateral claw, while 37% of foot lesions occurred in abnormally shaped claws. Limb lesions accounted for the remaining 16.8% of lesions, and 50% of these lesions occurred in the hip and stifle, while trauma was the main cause of limb lesions.
