| Popis: | An in vivo fecal egg count reduction (FECR) test was conducted on 5 farms in the southcentral United States participating in an animal resistance selection project to assess internal parasite resistance to anthelmintics. Seventy-six Kiko does on farm G1, 54 Spanish does (G2), 37 Katahdin sheep (S1), 61 Dorper ewes (S2), and 80 St. Croix sheep (S3) were randomly allocated within farm to control and 3 classes of anthelmintics. After determining initial fecal egg count, recommended doses of anthelmintics were given and fecal egg count was assessed 7 to 8 d later. Resistance to eprinomectin was detected on all farms, with FECR 95%). There was resistance to albendazole on 4 farms (FECR P P > 0.10) for G1 and S1. In conclusion, resistance to common anthelmintics varied considerably among farms and products, suggesting a need for such testing rather than general treatment recommendations. |
