What makes NZ milk so good?
New Zealand’s pasture-fed cows produce some of the best milk in the world... here’s why
You are what you eat. And it’s no different for cows. The quality of the milk they produce is directly related to their diet and environment. So it’s no wonder that New Zealand’s pasture-fed cows, feasting on our lush green grass, produce some of the best milk in the world.
And it’s this milk, full of natural goodness, that we’re proud to take to the world as the leading global dairy exporter.
Thanks to New Zealand’s temperate climate, cows here can graze outdoors all year round. And being predominately grass-fed (rather than grain fed) their milk is richer in omega-3 fats, vitamin E, beta-carotenes and CLA (that’s a beneficial fatty acid called conjugated linoleic acid).1,2,3,4
These important nutrients, along with our rigorous testing and quality standards, enable us to meet the highest customer expectations.
But let’s dig a little deeper to discover what’s behind each of these elements and why they’re so important.
Why fatty acid balance is important
The benefits of essential fatty acids like omega-3 and omega-6 are well known. But what’s also important is the balance of these fatty acids. And new evidence suggests that a balanced ratio of omega-3 and omega-6 fatty acids (e.g. 50/50) is important for human health.5 As you’ll see, pasture-fed cows (like the ones here in New Zealand) produce a preferable balance compared to those fed a higher proportion of grains.1
The more grass in a cow’s diet, the higher the quality of the milk in terms of its polyunsaturated fatty acid composition.
High proportion of CLA
Emerging evidence has shown some exciting positive health benefits of CLA including potential anti-inflammatory properties.1
Further detailed research is ongoing, but right now it’s reassuring to know that pasture raised cows have a greater concentration of CLA in their milk (up to twice as much) compared to grain-fed cows.2
Glowing with beta-carotene
If you’ve ever wondered why your New Zealand butter has a beautiful natural golden colour, it’s all down to the beta-carotene.
Beta-carotene is a precursor for vitamin A (which means it’s able to be converted to the active form of vitamin A). Vitamin A is an essential antioxidant and we need it for healthy skin and mucus membranes, our immune system, and vision.
Beta-carotene is found in substantial amounts in some fresh plant food, like grass. So milk products from pasture-fed cows may have a higher concentration of this nutrient.1,3,4 Another reason why New Zealand cows produce the some of the best milk in the world.
Packed with vitamin E
Another health benefit growing in our lush New Zealand grass is vitamin E. Milk from grass-fed cows generally has a greater concentration of vitamin E compared with cows fed unfortified grains.1
Vitamin E is a fat-soluble nutrient found in many foods. In the body, it acts as an antioxidant, helping to protect cells from the damage caused by free radicals.
There’s also evidence to suggest that the vitamin E concentration in milk from pasture-fed cows reduces oxidation in milk3 which in turn can improve the flavour.
All of these nutrients help make our New Zealand milk an amazing and unique food from nature that we’re proud to take to the world.
