Key Points

The research aims to explore how age and lameness history influence bone development in the distal phalanx of pasture-based dairy cows.
Conducted an ex-vivo assessment using digital photographs to analyze bone development.
Evaluated the relationship between age and lameness with bone structure in dairy cows.
Compared findings to existing micro-CT data for potential correlations.
Indications that both age and lameness history may influence bone development in cows.
Findings are preliminary, requiring further research to validate the associations.

Implication

Investigates the impact of age and lameness on bone development in dairy cows, suggesting further exploration is needed.

Abstract

Photography may provide an economical alternative to micro-CT for studying digital phalanx bone development in ex-vivo samples. Our data suggest lameness and age may affect bone development in pasture-based cows. However, these are preliminary data; further research is needed comparing CT and photography measurements, and to better understand the association between age, lameness and bone development in pasture-based dairy cows.
