A. Varadharajan & R. Vijayalakshmi

Faecal egg count reduction tests (FECRT) were conducted on goat flocks of all the six taluks of Cuddalore district of Tamil Nadu, India to determine the efficiency of anthelminitics (Feubendazole, Levamisole and Ivermectin) used for treatment against nematode parasites. The results of the present study revealed high levels of anthelminitic resistance to Fenbendazole treated goats of all over the flocks of Cuddalore district with the reduction of 74 – 91 per cent, whereas, the goat flocks of Chidambaram, Cuddlore and Vridhachalam taluks found to be low resisitant to Levamisole with the faecal egg reduction of 91, 91 and 90 per cent respectively. Ivermectin was found to be effective in controlling nematodes in all the farms. The post-treatment (fenbendazole and levamisole) larval culture revealed the presence of Haemonchus contortus larvae.
