Alternatives to traditional anthelmintics to control gastrointestinal nematodes in grazing meat goats.

摘要: Studies were conducted to determine the efficacy of a commercial herbal dewormer (HDC, 1 and 2) tanniferous perennial legume (Study 3) reduce fecal egg counts (FEC) in grazing goats (Capra hircus). Goats grazed Festuca arundinacea 1), Lolium multiflorum L. 2), Lespedeza cuneata or Tripsacum dactyloides 3). In study 1, eggs per gram (EPG) feces from orally-drenched weekly with HDC decreased 1,006 758 by Day 33, then stabilized at mean 740 EPG until end trial (Day 103). Conversely, FEC drenched ivomectin (IVO) 935 163 26, steadily increased 646 103. The differed between IVO on 12, 19, 40 (P <0.0001), 47 <0.007), 54 <0.07), 61 (P<0.002), 68 <0.04) 89 (P<0.09). Study 2, neither oral fenbendazole nor one two doses had an effect FEC, indication resistance gastrointestinal nematodes. 3, T. for 5 wk 860 500 former 1630 2310 latter <0.06). Thereafter, switched 1595, 1120 410 during following 3 wk, whereas still 220, 195, 70 <0.007, P <0.02, <.09, respectively). Within confines studies showed some no effectiveness reducing infected pastures, there was significant reduction cuneata.
