Digestion

Casein produces a curd when in the stomach. It is well known that goat milk produces a very loose curd structure with a high proportion of water and is easily broken apart.1 A loose curd structure promotes the digestion of milk proteins.2 The structure of the curd is in turn influenced by the individual casein proteins.

There are 4 casein proteins – αs1-, αs2-, β- and κ-casein. In cow milk, αs1-casein makes up around 25% of the total protein.3 In goat milk from New Zealand αs1-casein makes up only 5-10% of the total protein. Similarly, around 5% of the total protein of human is αs1-casein.4Instead as1-casein, β-casein makes up 70% of casein in goat milk compared to 69% in human milk casein and 43% in cow milk.5

Low levels of αs1-casein are associated with a loose, more fragile, curd structure.6 It is probably the fragile curd of goat milk that changes how it is digested within the stomach and therefore how the infant may react during this process.

Dairy Goat Co-Operative Trust

The Dairy Goat Co-operative’s 72 shareholders farm in some of New Zealand’s premium farming regions – Northland, Waikato and Taranaki. Their ability to do what they do, is enabled by the strength and resilience of the communities which they support, and which support them.

Spray Drying

DGC’s spray drying plant has been designed specifically to process goat infant formula.

Spray drying is the process of removing water from the milk, producing the beginning of the fine powder that is eventually found in the finished product.

Our spray dryers are kept meticulously clean and the most recent, second spray dryer was built in 2015.

Milk collection & delivery to factory

DGC has end to end production facilities on its site in Hamilton, New Zealand.

Milk is collected from our farms and delivered directly to the production facility. We take great care for our milk, ensuring a consistently lower temperature at all times by insulating our milk trucks. This helps maintain the nutritional integrity of our Goat Milk at all times during transit.
When the whole goat milk is delivered to the site it is checked again for quality before it is processed.

The milk that enters the DGC facility leaves as goat milk formula, in the can that is then sold to our partners’ customers. To ensure the safest possible production system, every element of the production is managed within our single site.

Co-operation

We are a co-operative, owned by the farmers who supply goat milk. We believe in the enduring value of the co-operative model and our objective is to grow the wealth and security of our farmer shareholders, while at the same time providing consumers with a world-leading premium quality product.

Co-operative is also a word we use to describe our business style, which is built around sustainable and long-term relationships with our partners.

We believe that goat milk is the best base from which to make infant formula. It is not the cheapest, or the most commonly available, but we do believe it is the best.

We take our responsibility seriously to deliver safe and effective nutrition to infants and young children all around the world, and to deliver brands and products that parents trust.
