Three New Fact Sheets Published

Three more fact sheets in the Best Management Practices to Control Internal Parasites in Small Ruminants have been published. So far, 9 fact sheets have been published. All fact sheets in the series are written and reviewed by members of the American Consortium for Small Ruminant Parasite Control (ACSRPC).

"Genetic Selection: Using Crossbreeding & Estimated Breeding Values" was written by Dr. Scott Bowdridge and Andrew Weaver from West Virginia University. "Proper Use of Dewormers" was written by Dr. Lisa Williamson (DVM) from the University of Georgia. Dr. Kwame Matthews from Delaware State University is the author of "Management of Coccidia."

Breeding Parasite-Resistant Polypays

The American Polypay Sheep Association is wrapping up a three-year project that could ultimately lead to enhanced parasite resistance for the breed. Funded by the American Sheep Industry’s Let’s Grow Initiative, the study uses the National Sheep Improvement Program’s system of Estimated Breeding Values, or EBVs, in looking to quantitative genetics for a solution to a key sheep production problem.

For the wool producer, hair sheep are not the answer. Those producers are looking to
identified genetic lines of Polypays with parasite resistance to attack the problem

that is likely to increase as producers increasingly rely on grazing marginal lands.

Selection for Low FEC in Cashmere Goats

Scottish researchers investigated the effect of selecting for low fecal egg count (FEC) in Cashmere goats. Goats from generations F2 through to F9 were monitored for FEC. They were compared to an unselected control line.

The study demonstrated that selected line animals excreted a significantly
lower number of parasite eggs in the majority of generations examined.

Differences Between Lab & Field

French researchers conducted laboratory and field experiments to determine the efficacy of Duddingtonia flagran spores. For all the trials, half of the goats received the spores while the other half acted as controls. For the dose titration trial, two dose levels were given.

Efficacy of the fungus was demonstrated in the lab, but not field.
