I'm looking for something a bit more for 15hh cob x. He's currently a nice weight, has lost a little condition recently due to being out of work but now starting him back and building up his fitness. I want him to hold his weight as he is now and not loose anymore so he will be needing a little extra. My normal "go to" would be a handfull or two of linseed however, hes had a virus and liver inflammation and my own research has led me to believe that oil and oil based feeds/conditioning feeds are not a good idea for horses with any form of liver issues. He's prone to being a bit silly/fizzy and has a lovely sharer at the moment who i'm keen not too scare off ;) so nothing with too much energy!Was wondering if bog standard high fibre cubes would be enough? I kind of have them in my head as "equine diet feed"Idea's
