Is this true, i. e. do they eat only grass and leaves, or do they get some supplement as well especially some ground carcass that can cause prior infection (I want to be able to eat the marrow as well)? Hi Hans, You are quite right New Zealand lamb 100% herded over here!!! We don't have the weather extremes of other countries so yes our lambs are ONLY fed on pasture, no ground carcass, we have enough natural feed here all year round!! During spring (Aug to Oct, approx) when the lambs are born there is abundant feed for them and their Mum's (ewe's). We live in the South Island where most of the sheep stations are (all many hundreds of acres). In the North Island it is mostly cattle and dairy with some sheep farms, smaller than stations. Hope this is a help to you, enjoy your marrow! Toni
