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 now listed according to their topic. The articles were written mostly by members of the consortium and cover a variety of topics. Of course, all topics pertained to internal parasite control in small ruminants:  sheep, goats, and camelids (llamas and alpacas). Some of the Timely Topics are available as fact sheets in PDF format. In 2022, the consortium began translating some of the more popular Timely Topics into Spanish.  In 2024, new Timely Topics will be published monthly and the old ones will either be updated or removed from the web site.  Contact us to suggest a topic for a Timely Topic.
