The present study was undertaken to find out the prevalence of gastro-intestinal nematodes in common peafowl (Pavo cristatus) at Lahore Zoo and to evaluate the comparative efficacy of Albendazole (Farbenda; Farvet), Levamisole HCI (Nilverm; ICI) and Oxfendazole (Systamax; ICI). Fifty two faecal samples of the birds were examined in Medicine Laboratory, College of Veterinary Sciences, Lahore with direct smear method and also flotation techniques for the identification of nematode ova. Forty two samples out of 52 were found positive (80.77%) for single or mixed infections of Capillaria spp., Ascaridia galli and Heterakis gallinae, the individual percentage; being 59.62%, 38.46% and 13.46%, respectively. Out of forty-two infected birds, forty were chosen for medication and divided into four groups, each consisting of 10 birds. (A= infected treated with Albendazole, B= infected and treated with Levamisole, C= infected and treated with Oxfendazole and group D= infect ed & untreated control). Faecal samples of experimental birds were examined for counting of eggs/gram of faeces on day '0' (pre-medication) with McMaster technique (Soulsby, 1982). The group D was kept as untreated infected controls. Faecal egg counts were again carried out on days 5 and 10 of medication and percentage reduction of EPG calculated. Oxfendazole was found to be the most effective (98.88%) among the three anthelmintics and levamisole the second most effective (97.93%). The Albendazole was the least effective (95.60%) anthelmintics in the study. The overall prevalence of gastrointestinal nematodes in common peafowl was found 80.77%.
