Whereas on the face of it you might expect most sheep to be pasture fed, this is far from the truth. The difficulties of raising sheep on a mixed farm mean that most lamb is fed with imported, wheat-based concentrate feeds (many of them containing GMOs), or at best is fed root crops or grain that could be used for human consumption.
Where sheep are fed grass, it is generally fertilised with artificial, nitrogen-based products that stimulate rapid growth, but which can cause problems for water courses and are made unsustainably from oil or mined minerals.
That’s why we decided to go for a totally pasture-fed regime. OK, it takes three times as long to mature our lambs, and we have to take care to nurture our series-rich pasture, but we feel better about it. No fertilisers, no sprays, no artificial feeds. Just lamb.
Oh, and it tastes better too.
