5. 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 % 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

6. SACs have a higher level of false positives than goats.
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
