Abstract

Nematodes resistant to anthelmintics are of increasing concern to sheep farms in Malaysia. Thus to ascertain the degree of anthelmintic resistance in the sheep population faecal egg count reduction (FECR) trials were conducted on sheep in the Veterinary Institute Kluang. A total of 60 weaned sheep were selected and divided into six (6) equivalent groups. Group A was treated with ivermectin Group B with Closantel Group C with Fenbendazole Group D with Levamisole Group E with Cydectin and the remaining 10 were untreated controls. Faecal samples were collected from each sheep before treatment and repeated on day 14 30 45 and 60 post treatment. The worm egg counts were estimated by using McMasters method. The population of worm was classified as resistant if the adjusted percentage reduction was less than 90. It is concluded that only levamisole can be used for helminthiasis control. The results showed that worms at the Sheep Unit of the Veterinary Institute Kluang was suspected to be resistant to Ivermectin Closantel and Cydectin. The worm population showed total resistance to fenbendazole. The strongyle population is mainly made up of 80 Haemonchus contortus and 20 of species were Oesophagostomum and Bunostomum.
