Selection for increased growth and impact on gait and skeletal morphology

Three experiments investigated the role of selection for increased growth rate and altered conformation on gait and skeletal morphometry, using either objective, quantitative gait analysis and skeletal morphometry techniques, or subjective scoring methods. The results of all three studies indicated that selection for increased growth rate and altered conformation had significant effects on both skeletal morphometry and gait in growing turkeys. However, because behaviour was unaffected, it was concluded that there was no clear evidence that the altered gait and skeletal morphometry caused by selection had negative consequences for turkey welfare. Growing turkeys provided with environmental enrichment such as elevated platforms, straw bales and outside areas use them without any negative impact on performance parameters.
