Timely Topics
Since August 2012, more than sixty (60) Timely Topics have been published to the web site of the American Consortium for Small Ruminant Parasite Control (ACSRPC). They are listed according to their topic. All of the articles were written by members of the consortium. They cover a variety of topics. Of course, all topics pertained to internal parasite control in small ruminants: sheep, goats, and camelids (llamas and alpacas). In 2022, the consortium began translating some of the more popular Timely Topics into Spanish. In 2024, new Timely Topics were published and some of the older ones were updated or removed from the web site. Timely Topics more than five years old are listed alphabetically at the bottom of the page.
Contact the author(s) if you have questions about the content of any of the Timely Topics.
