What is my horse lacking in nutrition?

My horse is constantly wanting to lick me (very unusual for her) and she is trying to eat her own poop. I feed her safechoice grain twice a day, bermuda hay, and she grazes all throughout the day. I also add 1 scoop of electrolytes to her nightly meals. Does anyone have a clue what could be wrong?
