Sand Cracks - prevention

[Mark Bowles]

I need some one to advise as to how to prevent sand cracks in hoofs starting.I have a 3 year old heifer in calf for the 2nd time that is showing small signs of cracks coming down from the coronet. I am spraying with an alcohol based tar type mixture that seems to be checking it but what causes them in the first place. All our cattle have their feet done once a year.
I fear it may be yet another mineral deficiency ( is that spelt right) but which one.

The suppliments most often used for hoof quality are Biotin, a vitamin, and zinc. Big time farmers can usually get their feed merchant to supply special requirements in quantity, not much help for us little people. If it is a serious problem I would ask your vet about using one of the horse hoof suppliments which are easy to get in Dexter type quantities.

I would be a little cautious about using anything spirit based as that mey well dry out the hoof and make the problem worse. an oil based product might be better.

If you are relying on grass or hay or silage for most of the year it may be that a general mineral suppliment might make a difference.
