Possible explanations for increasing frequency of straight hock angles in dairy cattle

Main subject area: Feeding, breeding period, management, genetic, bone structure

Short project description

In the latest years more Danish dairy cows have extreme straight hock angles (rear leg, side view).

Though the frequency is still low this is problematic since these extreme cases often lead to early culling. In this study you can focus on which consequences very straight hock angle can have for dairy cattle and find possible disorders related to straight hock angles.

Furthermore, there will be a need for a possible explanation for very straight hock angles and thereby a suggestion how to avoid these in the future. We hypothesise that feeding management in the rearing period may affect the development of the hock joint. There might also be an influence from genetic.
