Here is a site with where you can sign up for alerts and weekly news digests. It's Farmed Animal Net. I like the self-description - Objective Information for the Thinking Advocate.
In case you wonder whether this is a front group for the beef or dairy industry (I did!), it is sponsored by the following groups:
Animal Welfare Institute
Animal Welfare Trust
The Glaser Progress Foundation
The Humane Society of the United States
