How milk gets to you – farm to fridge

The first step in the production of all foods is the process of photosynthesis. Green plants produce carbohydrates (sugar) in the presence of sunlight, water and air.

The cow’s diet is very important as it determines the quality and quantity of milk she will produce. A cow produces milk in the udder, where it is stored until she is milked.

A cow needs 15–20 kg of feed and 45–90 l of fresh water a day. Cows eat grass (pasture), hay or silage. Licks containing salt and other minerals may also be provided to supplement the diet. On average a cow produces 20L of milk per day.

Cows are important farming animals. Their milk can be used for drinking and also to make products such as maas (amasi), yoghurt, cheese, butter and cream.
