| dc.description.sponsorship | A study was conducted to determine the efficacy of albendazole, levamisole & oxyclozanide (MilsanR) and ivermectin anthelmintics in selected sheep farms in Arusha, northern part of Tanzania. Nine study farms were screened, in each farm a total of 100 sheep were selected for faecal egg count reduction (FECR) test. Resistance was assumed to be present if egg count percent reduction was less than 90%. A study questionnaire was also administered in each farm to determine the worm control management practices. Albendazole resistance was found in the nine resistance was detected in the nine farms with percent reduction ranged from 69% to 87%. Ivermectin resistance was also found in the nine farms, percent reduction ranged from 74% to 90%. Based on larvae identification from faecal cultures, the most predominant nematode species in the resistant population were Haemonchus and Trichostrongylus. The questionnaire survey revealed that all farmers examined use anthelmintics for the control of womi infection in sheep. Albendazole was used by 66.7% of the farmers, levamisole 22.2% and nitroxynil by 11.1%. Most farmers (88.9%) had used the same type of anthelmintic for five or more years and 66.7% administered anthelmintics themselves. 22.2% of farmers treated sheep twice per year while 22.2% of fanners dewormed every month, 11.1% of farmers dewormed every three months, 11.1% dewormed when animals fell sick and 33.3% of farmers dewonned when they got money. Worm infection was ranked the second most important constraint of productivity in sheep in most farms. It is concluded that anthelmintic resistance is widely spreading and becoming more serious than farms, the percent reduction ranged from 67% to 87%. Similarly MilsanR previously anticipated. The magnitude of this problem in the country should be assessed and remedial solutions found in order to save the farmer from economic losses attributed to this problem | |
