What's this...stuff in the hogs mouth and eyes?

[Robert20]

I recently shot a large sow with my bow, and after letting her lay for a little while and then a slow, painfull tracking job through thorn infested woods.....I finally found her.

She had something in her mouth and covering most of her eyes. It looks like dried cornbread batter. I know that sounds stupid, but it's the only thing I can think that it looks like. It's all caked up and light yellow.
