It's alfalfa/ oatHAY, poppy. It's harvested before the oats are ripe and is a pretty high octane hay. Slightly more energy than grass hay, sweet, and horses love it. If you could get it as hay, not pelleted, would be even better. It's pretty coarse, keeps them digesting and therefore warm.
But try to find alfalfa hay and give alfalfa pellets. Never tried the sunflower meal, so cannot comment on that. And up the ricebran and beetpulp.
If she is in free choice hay and her teeth are okay, the hay is most likely not very nutritious.
