The Link Between Disinfecting Navels and Mortality
Over a decades long period of time I have been advocating disinfecting navels on newborn calves. In the Calf Facts library at our www.atticacows.com website I have three posts about navel dipping - one of them is Dipping Navels: Dollars and Sense [click HERE to go there].
A newly published study of dairies with automated milk feeding systems (26 dairies from the US Upper Midwest) collected data on mortality and disinfecting navels.
Here are the results: [average rate of mortality]
No navel disinfecting [22% of farms] = 7.3% mortality
Yes, navel disinfecting [78% of farms] = 3.0% mortality
57% of the farms reported mortality rates less than 3 % with one dairy having a 13.4% death rate.
We suspect that there are other best management practices that go along with disinfecting newborn navels that, in part, are also connected to calf mortality.
