If you are using brontos, gigas, or carcharos to impregnate here's a fair warning that all 3 dinos listed above will run out of food faster than they can eat it (1 second per item eaten) so when their food reaches 0 they can starve to death despite having food in their inventory. To prevent this manually force feed it food until its hunger bar is full or if you're on singleplayer put a lot of food in it, leave your game and rejoin and the dino will have automatically eaten until its food bar is full or all the food in its inventory disappears. (This doesn't work on pc)
