    Summary
    This summary is machine-generated.

    Windswept deformities, characterized by limb angulation, were more prevalent in turkeys than broiler fowls. These conditions may be linked to physeal disturbances in the lower leg bones.

    Area of Science:

    • Veterinary Pathology
    • Avian Medicine
    • Skeletal Biology

    Background:

    • Windswept deformities, defined by contralateral valgus and varus angulation of intertarsal joints, are observed in poultry.
    • These deformities are a significant cause for culling due to lameness in turkeys and broiler fowls.

    Purpose of the Study:

    • To investigate the prevalence and characteristics of windswept deformities in turkeys and broiler fowls.
    • To explore potential correlations between limb angulation, bone torsion, dyschondroplastic lesions, and physeal disturbances.

    Main Methods:

    • Examination of 120 turkeys and 120 broiler fowls culled for lameness.
    • Assessment of limb angulation (valgus and varus) and intertarsal joint deformities.
    • Histopathological evaluation of physeal regions in affected limbs.

    Main Results:

    • Windswept deformities were identified in 75/120 turkeys and 24/120 broiler fowls, indicating higher prevalence in turkeys.
    • Nearly 70% of broiler windswept limbs with significant angulation showed physeal disturbance in the distal tibiotarsus or proximal transometatarsus.
    • No correlation was found between abnormal bone torsion, limb angulation, and dyschondroplastic lesions.

    Conclusions:

    • Windswept deformities are more common in turkeys than broiler fowls.
    • Physeal disturbances in the distal tibiotarsus and proximal transometatarsus are frequently associated with severe windswept deformities in broilers.
    • The causal relationship between physeal lesions and windswept deformities remains uncertain.
