Forage Effects on Parasites

Use of legumes and forbs that contain plant secondary compounds may reduce fecal egg counts and/or improve overall protein nutrition to help animals better tolerate effects of internal parasitism. During 2009 and 2010, researchers at the Appalachian Farming Systems Research Center in Beaver, West Virginia, monitored the performance and parasite status of meat goat kids finished on chicory, birdsfoot trefoil, or red clover pastures. Goat kids grazing red clover had greater overall average daily gain compared to those grazing chicory. Birdsfoot trefoil was intermediate. When averaged over both seasons, there was a weak trend for kids grazing chicory to have higher fecal egg counts than those g

Terrill Selected as Fullbright Specialist

Dr. Thomas Terrill, Coordinator of the American Consortium for Small Ruminant Parasite Control (ACSRPC) was selected as a Fullbright Specialist. Terrill is an Associate Professor of Animal Science at Fort Valley State University (FVSU) in Georgia. A Fulbright Specialist is a researcher or academic scientist selected to participate in a two to six week project- based exchange at institutions across the globe. The purpose of a Fulbright Specialist is to serve as an expert on a short-term basis for governments, universities or non-governmental organizations with a need in a specific area. As an appointed Fulbright Specialist, Terrill will be listed on a roster as an expert in goat and sheep par

Bred For Florida

For sheep to survive in Florida's humid, sub-tropical climate, they have to have some degree of parasite resistance. Otherwise, they’ll constantly struggle with parasites (worms) and/or need to be raised in confinement. Several of the breeds raised in Florida strive to meet this requirement. Image from Calovine Farm. Taken by Beth Senn The St. Augustine is an improved breed of hair sheep. It is a cross between the St. Croix (5/8) and Dorper (3/8). The St. Croix was selected because of its mothering ability, parasite resistance, and hardiness. The Dorper was valued for its size and muscling. Ron & Ruth Taber (Calovine Farm) began developing the St. Augustine breed in 1991. According to the

Efficacy of Anti-Coccidia Drugs in Goats

Researchers at Texas A&M University compared the efficacy of two anti-coccidia drugs. One hundred and fifty young goats, housed on concrete lots, were randomized to received either amprolium (50 mg/kg once a day for 5 days by mouth) or ponazuril (10 mg/kg by mouth once) if they had fecal oocyst counts >5,000 per gram. Both treatments resulted in decreased oocyst counts post-treatment compared to before treatment. There was no significant difference between fecal coccidian oocyst counts between goats in each group. There was no significant difference in body weight between goats in each group. This study showed that both amprolium and ponazuril were effective in decreasing fecal coccidia oocy
