ABSTRACT

 

A comparative efficacy test for three broad-spectrum chemical anthelmintics and three plant extracts was carried out using naturally infected Red Maasai cross sheep at the Veterinary Science Research Institute in Muguga in October 2015. A group of 42 sheep was randomly assigned to seven groups of six sheep each, based on faecal egg counts and age category. Each of the first three groups was treated with a Benzimidazole, Levamisole and Ivermectin injection according to the manufacturer’s recommendation while the other three groups were treated with three herbal extracts according to recommendations by the practitioner. The efficacy was based on the faecal egg count reduction on Day 14 post-treatment.The efficacy of the broad-spectrum anthelmintics was 75%, 81% and 97% for the benzimidazole, ivermectin and Levamisole respectively. All the herbal extracts had low efficacies of 25%, 34% and 37%. It was concluded that levamisole showed a higher efficacy compared to other anthelmintics and plant extracts. Thus levamisole can be useful for controlling gastrointestinal nematodes in Muguga.

Key Words: Anthelmintic resistance, gastrointestinal nematodes, Helminths, Sheep.
