Even trying to feed excel forage as this as a very low calcium level. Hope piglet makes a recovery soon though.</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/110457?ContentTypeID=1Thu, 17 Mar 2011 07:43:44 GMT1a0763ec-3885-442c-853e-6cef656dfec5:c19db5f7-7a23-407e-86cf-3ca68254a176Nicola Smith<p>Hi, without looking it up etc my initial opinion would be maybe owner feeding too many dark leafy greens high in calcium - I know my 1 pig gets chalky weeif he has too much spinach. I would encourage them to feed plenty of lower calcium greens, minimum pellet and plenty of fresh grass and hay.</p> <p>I may be wrong just my initial thought!!</p><div style="clear:both;"></div>
