It takes a lot of science to make our dairy farm tick these days. Our place is no factory farm either. With around 250 free-range milking cows, it’s a very typical Australian dairy farm.
Yet, only today, I have been keeping four different labs busy:
Environmental lab: what’s in our water?
We’re considering moving the water supply from the river to the dam but need to be sure the water is up to scratch first. While we don’t irrigate our farm, we need high quality water for the cows to drink and to keep the milking machinery hygienic and sparkling clean. We’re having it tested for minerals and nasty bugs like e-coli.
Animal health testing lab – looking for hand grenades in the grass
Our farm has volunteered to be a ‘sentinel’ for the spores that cause the life-threatening condition of facial eczema. Collecting samples from a couple of paddocks only takes a few minutes but it could save hundreds of cows untold suffering.
Dairy nutrition lab – feeding the bugs that feed the cows
Yesterday, someone on Twitter asked Dr Karl how cows manage to get fat on grass while humans lose weight on veggies. The secret lies in four-chambered guts filled with life-giving bugs that do a lot of the work for the cows.
Our bovine ladies are athletes – each gives us around 7,000 litres of milk per year – and they and their bugs demand nothing short of perfection from us as chefs! Feed reports allow me to balance the cows’ diets with the right mix of fibre, energy and protein.
Soil nutrient lab – getting the dirt on our soils
Soil data allows me to apply the right fertiliser in the right amounts to the right places – lifting the productivity of our farm, reducing costs and preventing leaching into the river. I test the soils of all our paddocks every year. Some would regard that as wildly extravagant but a $110 test is nothing compared to the cost of a tonne of excess fertiliser.
Dairy farming is still the earthy, honest lifestyle it always has been but, these days, it pays to be a touch tech-savvy as well.
EDIT: Oh my goodness! Mike Russell (@mikerussell_) just pointed out that I forgot the bleeding obvious: the testing of our milk! It’s tested to an inch of its life – fat and protein content, sugars and cell counts are all tracked daily. Thanks Mike!

Off topic but have you seen this milk ad Marian? I love it!
Oh dear – looks like we have a broken link. What was it for, Ian?
Oh yes, Cravendale’s “Cats with Thumbs”! Lots of fun!
Have a look at this Cravendale teaser trailer too!
