Teat-spray is one of the most important things you can be doing to control and minimise the spread of mastitis. We commonly use
either iodine or chlorhexidine based teat-sprays. Teat-spray is always important, but this in particular is a crucial
period to have effective teat-spray in your herd for two reasons: Firstly, with the weather turning we have seen rising cell counts and
increased cases of mastitis lately. Secondly, in the months leading up to dry cow therapy, effective
teat-spray is crucial to reduce the risk of mastitis at or soon after dry off.
Teat-spray is important for two reasons. Firstly, it is the only way that we can kill bacteria that are present on cow’s teats both from
the environment and from the milking machine. These are bacteria that can cause mastitis. Secondly the emollient present is important in maintaining teat skin condition. The two factors that determine the effectiveness of teat-spray are
the concentration that the teat-spray is mixed and the coverage on the cow’s teats. A recent study showed only 12% of farms in
New Zealand had adequate mixing concentrations along with effective coverage. When teat-spraying cows it is vital that not
only is teat spray mixed up at the correct concentration (high risk concentration at this time of year), but that all surfaces of all teats
are covered including the whole teat barrel. If any areas on the teats are missed, the bacteria will survive and can cause mastitis, if these bacteria pass into the teat canal. If you are at all concerned about your teat-spray coverage or concentrations, or would like any ideas about how these can be improved, please contact your local Vetent clinic without delay.
