Yup I want Rubic to be somewhere between 400-450kg so was feeding her 6kg hay (all soaked) and 2 small bucket feeds a day when she was in 24/7 and she was steadily losing weight. I got her down to 455kg however she put on 20kg when she went out in the new paddock. I think she stuffs her face and I'd say she is getting about 4kg soaked hay overnight which I'm gradually reducing however I feel extremely mean as it won't last her long at all overnight no matter what I do with it! Hopefully in this field she will be moving round a bit more to get the grass and it isn't so rich that will help.
