I ask this question because I am going to try a new feed. My guy gets an 8oz cup of Intregrity Lite am and pm plus 14 pounds alfalfa/bermuda pellets split into two feedings. I want to discontinue the Integrity and start Equidae Alfalfa plus or the Coastal I haven't decided yet. But I was looking at the feeding calculator and their is a pound difference in maint. And light work. I work with him everyday for about an hour sometimes two but that's it for the day. Should I feed according to maitenance or light work? Or should I just start low and see what his body condition does? He is a little underweight I don't want to fatten his so much as build lean muscle especially on his back. We have been working on some back strengthening exercises.
ETA: Sorry I used the feed calculator and it was a 3 pound difference
