These are just my thoughts: You need to know how many pounds of feed you are feeding daily, you need to be able to monitor your animals weight so you can tell if it is gaining at an acceptable rate. You need to budget for a good feed wether it be bagged or bulk it needs to be a good balanced ration to help your animal reach it potential. it sounds like your animal is getting what we call sweet feed or 4-way, it will not help the animal gain like it should. Good feed cost more for a reason, it has more in it, stuff your animal needs to reach its potential.
Is your animal feed by it self or with others? If it is fed with others there is really no way to know how much grain it is receiving each day.
If you know how much feed you are feeding and how much gain you are getting, you will know if your animal is on track, when and if you need to increase feed or change feed, add supplements slow them down; water ever you need to do.
If you are going to run him in a pasture, you need to run him into a pen in the morning rinse and feed him tie him under fans in the shade during the day, feed him in the evening after he has finished his feed, kick him back out into the pasture. Our calves run on grass but they eat the grain and hay and just lightly graze during the night.
My suggestion is take what you learned this year make some changes in your program and give it heck again next year,I think you will like your results.
