A total of 130 faecal samples were collected from various breeds of parrots. Eighty eight samples were found positive for single or mixed infection of Heterakis gallinae and Ascardia galli. Faecal samples were examined for counting of egg/gram of faeces using McMaster egg counting technique having overall prevalence of 67.70 % with individual relative percentage as 73.86 and 26.14 respectively.The birds were divided into four groups; group A, B, C and D. Group A was treated with albendazole, group B with Levamisole, Group C was kept as untreated infected control and group D was untreated and uninfected control. Albendazole was found to be highly effective (96.33%) as compared to levamisole (84.90%) against gastro-intestinal nematodes in parrots.

It adversely affects the common peafowl (Pavo cristatus) (Ashraf, et al., 2002) health of birds during heavy infestation.
Parrots are beauty of nature and contribute a lot This study will help the game bird owners about in eco-system and are commonest fancy game birds helminthiasis, its treatment and control, to minimize the through out the world. Parasitic infestation although are not acute in nature but are cause of continuous and sustained economic losses in birds. The gastro-intestinal MATERIALS AND METHODS
