For someone that does not know one can equals 2pounds, etc. . If I change any feed it is weighed first. 

When in your feed plan does the cubed hay is added?  Like when they can’t graze or there is poor forage??

You'll have to forgive me. I'm a total type A personality lol! 

I did weigh them once in the scoop I use so I have a rough I idea how much they're getting. 

I added it to their diet for two reasons. I have a super old mare that was having a hard time gaining weight even with free choice hay and quite a bit of senior with amplify daily. I water them down to almost a slop and they're much easier for her to eat. 

My other mare was diagnosed with a mild case of EPM and I was looking for more ways to get vitamin E in her diet, in addition to suppliments. Since alfalfa is higher in e than regular hay, I decided to give her a bit daily too. (We are treating her with meds, of course).
