I have a 15year old horse, who grazes for a few hours each day but mainly has haylage and a small bit of hard feed. I bought some linseed the other day by accident, thinking it was something else, but when I realised I thought I'd check out what it was used for, and the benefits seem to be fitting for my horse seeing as she mainly has haylage for forage. BUT then got all worried after reading all these dangers of the acid hurting her if it wasn't prepared right and now I'm not sure whether to give it to her or not.... It isn't in the form of oil, it is what i THINK is referred to as a 'linseed cake' although not completely sure of that, it is solid and about the size of a 2penny piece, but rectangular, and looks almost like a dark brown biscuit. Is it safe to feed her this type of linseed without having to prepare it in any way before hand or do i need to soak and boil it as you do with the oil?
