In The present investigation biochemical components of cestode parasite Cotugnia spp. from host Domestic chicken (Gallus gallus domesticus) has been studied. Analysis of major biochemical constituents of genus Cotugnia revealed that the total glycogen, protein and lipid contents (in milligrams) 0.15 mg, 0.11 mg and 0.04 mg respectively. Glycogen content was relatively high showing Carbohydrate as a main energy source in this parasite followed by protein and lipids (Carbohydrate> Proteins> Lipids). This holds true for a parasite living in an anaerobic environment like the gut.
