I discovered this handy tool late last year.
FeedXL
It's fantastic! I had been wondering how much feed Max needed, considering the
small amount of work he does, and the
HUGE amount of grass this season. A toxin binder is definitely needed, especially with him coming over all itchy in October. We had an incredibly wet winter and early spring, and so the paddocks were very lush (well, for this part of the world). Horses all over the Bay were displaying all sorts of behaviours that could only be attributed to too much good grass, and endotoxins. My farrier said he'd never seen so many crazy horses.
Max started scratching on anything he could get near, even rubbing his hair off in places. If I had someone to take photos, I could've got some great ones of his goofy/appreciative face as I scrached his neck. Note to self- start taking the camera everywhere.
So anyway, it seems that the little fatty-puff is doing just fine on a handful of chaff, a cup of sugar beet, minerals and toxin binder. He is lacking in selenium and vitamin E, according to the analysis and I know the soils around here are low in selenium. BUT it is a very dangerous thing to overdose a horse with (their hair and hooves can fall off!) so I am thinking of consulting the vet first. I might have to get him in anyway about the itchiness which has returned with a vengence.
