Our GOS have a lovely smell, slightly curry, certanly not piggy.
Easiest way to load GOS if you have a trailer available for a few days. Leave feed, bananas apples in a trailer, moving them further towards the back each day. Curiousity and greed will have them walking in quite quickly. On slaughter day just shut the door.
if the ramp is very steep, its easier to load them using straw bales under the ramp. For some reason they dont mind climbing up but dont like a steep walk.
