Commodities

• Animals: goats

Practices

• Education and Training: farmer to farmer, on-farm/ranch research
• Production Systems: integrated crop and livestock systems
• Sustainable Communities: sustainability measures

Practically all goat farms have unsustainable devastating animal losses from internal parasites, in particular, Haemonchus contortus (H. contortus) and copper deficiency. A high percentage of goat farms are becoming resistant to dewormers and have begun to turn to copper boluses to treat H. contortus. Now more than ever, goats are becoming deficient or toxic in copper.

The SARE grant require communications with several goat associations, and having lab tests run on goat livers to prove deficiency or toxicity in their goat herd. Most farmers do not do necropsies nor send liver samples due to the extra expense it would add to their budget. Getting liver samples from harvested animals is the only logical, safe way to make the determination of toxicity or deficiency. When goats die prematurely, the cause is almost always assumed to be internal parasites, but if they knew their animals were copper deficient or toxic in copper, rather than overloaded with internal parasites from resistant dewormers, it would be a cheap fix to change treatment procedures to give copper boluses to prevent premature deaths. Currently, there is an overuse of dewormers on goat farms and overuse creates several issues: chemical contaminants in manure which is bad for the soil; reduction of dung beetles; and unsustainable and unnecessary expenses to the producers. But the most important is resistance to dewormers.

Our scientific solution to the problem of copper deficiency versus toxicity and the overuse of dewormers will require working with the South Carolina Veterinary Office to oversee the research, acquire liver samples from harvested goats, and invite members of several goat associations to be part of the research.

Acquired samples will be sent to a private laboratory and the SC Veterinary Office will assess the samples and give a report of the results. The results will show the levels of copper, and levels of compelling and antagonistic minerals. The results will substantiate suspected beliefs, and the report will provide proof to producers what they should be doing regarding deworming versus dosing or not dosing copper to eliminate H. contortus parasites.

Cooperators will send invitations and newsletters to let goat farmers know about the study and get them on board to get liver samples and attend workshops to learn how to do a simple necropsy.

The producers that participate in the research project will be required/asked to keep accurate records of monies spend on dewormers, copper boluses, and dosing supplies. Producer records and the Excel document information will be used to compare year one to year two.
