The objective was to evaluate conventional and alternative anthelminthic action on the sensibility of gastrointestinal nematodes in goats. Hundred and twenty goats of both sexes were distributed into 10 groups of 24 animals each (12 males and 12 females) and submitted to treatments of specific anthelminthic composition. The commercial drugs used were moxidectin 0.2%, albendazole, levamisol chlorhydrate, ivermectin and an aqueous extract of the purgative potato (Operculina hamiltonii). The reduction test was applied through egg counts per gram of feces and larval culture to evaluate resistance. The fecal samples were collected in the day when medication was accomplished (day base), at 7, 14 and 21 days after treatment. The following results for the reduction of Trichostrongyloidea eggs were obtained: Treatment of the females with Moxidectina reduced the egg counts to 92.8, 88.7 and 89.8%, of the males to 92.6, 96.2 and 98.1%; with Levamisol of the females to 96, 97.1 and 91%, of the males to 85.7, 94,2 and 100%; with Albendazol of the females 65, 60.3 and 75.4%, of the males 88.8, 88.8 and 55.5%; with Ivermectin of the females to 92.2, 68.6 and 70.6%, of the males to 41.7, 73.6 and 59.7%; and with the purgative potato of the females to 31.8, 34.1 and 49.4%, of the males to 61.5, 80.7 and 50%. In larval culture Haemonchus, followed by Bunostomum, Trichostrongylus, and Oesophagostomum, were identified even after treatments. |
