Goat milk secretion

Milk is made up of protein, fat, carbohydrate, water, minerals and vitamins. These components are packaged inside cells within the mammary gland and are released from the cells by two different pathways of secretion.1

  • Merocrine secretion
    proteins, lactose, minerals and water are released without disruption of the cell.
  • Apocrine secretion
    milk fat is enveloped by the cell membrane before being pinched off from the cell. In this process some of the cell components are also released into milk.

Milk proteins consist of whey and casein proteins. There are 4 casein proteins – αs1-, αs2-, β- and κ-casein. Low levels of αs1-casein cause the proteins, lactose, minerals and water in milk to be secreted by the apocrine pathway.2In New Zealand goat milk αs1-casein makes up only 5-10% of the total protein. Similarly, around 5% of the total protein of human is αs1-casein.3

As a result much of the proteins, lactose and water in both goat and human milk are secreted by the apocrine pathway. In cow milk, however, around 25% of the total protein is αs1-casein.4 Therefore, proteins, lactose and water in cow milk are only secreted by the merocrine pathway.

Animal Welfare and Health

New Zealand has a strict Code of Welfare for Goats. It specifies what is considered to be optimal animal welfare and how this may be achieved for goats farmed under New Zealand conditions. DGC farms are required to follow the New Zealand Code of Welfare for Goats as well as DGC’s own Code of Farm Practice.

Blending

Our state of the art blending plant enables us to add the additional nutrients required to meet regulatory and specific product requirements where necessary.

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.

Can Filling

The DGC can filling facilities are world class. On any day at DGC we can manufacture over 150,000 cans and fill over 90,000 cans. These are then sent to our warehousing and distribution facility where they await final safety tests before being released for export worldwide.
