DairyTalk 330: When Hindlimbs Fail: Holstein Muscle Weakness Raises New Concerns in Dairy Breeding - by Helmut Demmelhuber

This podcast episode is based on a technical article examining an
emerging health concern in Holstein cattle involving sudden
hindlimb weakness and mobility problems in young cows. The
condition, often described as hindlimb stiffness syndrome,
appears to result from a combination of neurological damage,
orthopedic disorders, and the genetic mutation known as Holstein
Muscle Weakness (HMW). The article links the spread of this
recessive trait to the intensive use of influential sires within
genomic breeding programs, which can increase the likelihood of
hidden carrier matings. As a result, the analysis highlights the
need for systematic veterinary documentation and broader use of
genetic testing. It also stresses breeding strategies that give
greater weight to structural soundness and long-term robustness
in dairy cattle populations.
