Parasite Resistance Webinar Set for Aug. 22
August 4, 2017

Sheep producers dealing with parasite issues will want to tune in for an education webinar with Joan Burke, Ph.D., a research animal scientist with the USDA Agricultural Research Service's Dale Bumpers Small Farms Research Center in Booneville, Ark. The webinar is scheduled for 7 p.m. central daylight time on Aug. 22.

Gastrointestinal parasite infection of sheep and goats is a major health issue that can cause anemia, reduced weight gains, poor performance, mortality and discouragement to farmers. Dewormer resistance limits the ability to control these parasites using available dewormers.

Because of moderate heritability, opportunities exist to improve parasite resistance through genetic selection programs. This will be discussed along with scientific background, what to expect and limitations. Climate, rainfall, management, sex of animal, rear type and age will influence parasite infection. Genetic resistance to parasite infection is arguably the best means of gastrointestinal parasite control. It can be achieved through selection of sires with favorable estimated breeding values in programs such as the National Sheep Improvement Program, which will be reflected by lower parasite infection measures in offspring.

The webinar is made possible with funding support from the Let's Grow Committee of the American Sheep Industry Association.
