Supplement similar to grand 4-t fyer

I am from canada so I can't get purina show chow feeds, I was wondering if anyone knows of a feed similar to grand 4-t fyer (a feed that can be mixed with corn,oats barley, etc. that supplies all necessary vitamins and minerals). I was thinking IMPACT F4624 Beef Supplement TM (507834) from masterfeeds but I don't know if that is similar to grand 4-t fyer

Kent has a couple different protein pellets similar I think.

I don't know if you can get showtec up there but they have one similar that we have used with success.

Has anyone used masterfeeds IMPACT F4624 Beef Supplement, if so do you know it's purpose, it's easily accessible where I live and it's the only one I know of up here.
