higher profit by using sires with high
hoof
health index there is a great difference in
hoof
health among sires. by choosing the best sires for this important trait, you get less
lameness
and higher profit. l ameness is one of the main reasons for economic losses in the modern dairy production. the majority of the
lameness
cases are associated with
hoof
le- sions. feed management, cow comfort and function- al
hoof
trimming are considered to be the main tools for effi- cient
lameness
control. the role of breeding in
lameness
con- trol is often neglected. yet, there are indications of considerable
genetic
variation of resistance to the
hoof
disorders. we know that some breeds are more resistant to
hoof
lesions (e.g. swedish red and jersey are more resistant to laminitis problems than hol- stein). farmers can also notice that under the same manage- ment conditions some individuals never get
lameness
prob- lems while for others the
hoof
health is always a concern. thus, similar to other traits, if there is an evidence of
genetic
variation there is a room for
genetic
improvement. direct selection more efficient factors behind
genetic
resistance to
hoof
lesions are many. the principal list of factors responsible for
genetic
resistance by evgenij telezhenko, phd in
