It’s rather interesting to know that Angus isn’t a cut or a type of meal—it’s a breed of cow that’s different from the usual. New Zealand plays host to an abundance of these cows, and so does Australia. But what makes New Zealand such a prime destination for Angus?

Just like chicken, free-range cows offer the best meat. Here’s how New Zealand does it:

Natural blessing: grass-fed. New Zealand has one of the best grasslands in the world, and it’s only natural for farmers here to let the cow graze free on the grass. Angus beef aren’t the only grass-fed cows here—even regular cows receive the benefit.

Natural blessing: wide area. There’s no shortage of New Zealand grass to feed to cows. About 40% of the land mass is reserved for agriculture and horticulture. Angus breeds and regular breeds, as well as sheep, have the best of this 40% available to them.

Natural blessing: Biodiversity and nutrients. The healthier a place is, the more it attracts life. Most of the grasslands are diverse ecosystems that sustain a healthy cycle of nutrients. These nutrients find their way into the Angus breed, which makes for healthier cows and better meat.

Warning: Dung in waterways. While there is a healthy ecosystem in place for creating healthy cows, you should watch out for their dung. Dung in water is not a good combination, especially since this could be the same water people drink, and not only cows.

Warning: Sediments. Keep an eye on where you wash dung and sediments too. Too much sediment in the waterways can disrupt the ecosystem. Freshwater species suffer the most from this pollutant.

Keeping the nature healthy is a main reason why Angus beef from New Zealand are considered some of the best in the world. People should also be wary that the health of the cows should also mirror their own health—hence, they should take care of the area.
