New Zealand, with a total land area larger than that of Great Britain and a population of only 4.5 million people is one of the least populated countries in the world. All this space, combined with plenty of fresh water and clean air, makes it ideally suited for agriculture. It is therefore no surprise that agriculture, and in particular dairy production, is the most important economic sector in New Zealand. In fact, New Zealand is the largest exporter to the world dairy market.All this milk is produced from New Zealand’s vast green pastures. Because of New Zealand’s favourable climate cows can be outside and graze all year long which allows them to behave and eat much more naturally. This is very different with the situation in most dairy producing countries in other parts of the world, where cows are kept indoors for a lot of the year and need to be fed grass stored from summer (forage) with grain added.
