Objectives
Obtain an overview of SAC farming in America
with a focus on parasite issues.
Prevalent worm in the area is H. contortus-LDA
LDA showed that 80 - 100% of the worms were H. contortus.
The rest trichostrongylus.
Noted N. battus
Determine the prevalence of anthelmintic resistant
GIN of llamas and alpacas in the southeastern U.S.
•GINs are now resistant to certain classes of anthelmintic drugs in
llamas and alpacas as evidenced both in vivo and in vitro
•Ivermectin as little as 57% effective in vitro
•Moxydectin still effective but dosage may need to be higher in
vivo
•explore novel approaches to controlling GIN
• feeding condensed tannin forages as a natural
anthelmintic
•doesn’t appear to work as well in SACs
•to determine the effectiveness of the FAMACHA system
in assessing parasitic burden in these species.
• SACs have a higher level of false positives than goats.
•Some SACs have pigmentation that prevents scoring
