I spent some time on the other side of the camera yesterday. We had a film crew here who were doing a series of stories for DAFF (Federal Department of Agriculture, Fisheries and Forestry) on the potential to reduce greenhouse gas emission’s from agriculture.
The crew was here to talk to me about feeding oils to dairy cows. Research from DPI Ellinbank has shown methane emissions are reduced by about 3.5 per cent for every 1 per cent increase in dietary fat.
We have fed very small amounts of vegetable oils to our cows for many years now to reduce the dust in the dairy. Each milking our cows are fed minerals such as calcium mixed with some crushed grain. This mix can be very dusty making the dairy an unpleasant environment for both cow and milker, so we add a little vegetable oil to the mix. This is a common practice on many farms and its good to know that while we are keeping the dust down we are also helping the keep global temperature down too.
