the_excerpt_rss() WordPress Function

The the_excerpt_rss() function is a great way to display excerpts of your latest blog posts in an RSS feed. This function takes care of all the formatting for you, so all you need to do is specify the length of the excerpt and whether or not you want to include a link to the full post.
