The present experimentation was conducted at Animal farm, Department of Animal Production, Rajasthan College of Agriculture Udaipur. One hundred eighty eggs was collected from four different chicken breeds (40 week old) were used in 4 treatments with 3 replications, each consisting of 45 eggs. The treatments were (T₁) Kadaknath, (T₂) RIR, (T₃) Mewari, (T₄) Pratapdhan. In this experiment nutritional composition of egg quality traits were measured to comparison of indigenous and improved chicken breeds. Results showed that the The dry matter was higher (p<0.05) in Pratapdhan (26.65%) followed by Kadaknath (26.31%), Mewari (25.91%) and lowest dry matter was found in RIR (25.31%). The crude protein (%) was found to be higher in Pratapdhan (11.59), followed by RIR (11.57), Mewari (11.47) and minimum crude protein was found in Kadaknath (11.33). Maximum ether extract percent (%) was found in RIR (11.30) followed by Pratapdhan (11.28), Mewari (11.26) and lowest value was observed in Kadaknath (11.17). Highest gross energy (kcal) was found in Pratapdhan (167.53), while lowest was found in Mewari (166.82). Though the differences in crude protein, ether extract, and gross energy values among different breeds were found to be non- significant. The ash percentage (%) was higher (p<0.05) in Pratapdhan (1.21) and Kadaknath (1.17) as compared to RIR (1.11) and Mewari (1.08). While moisture percentage (%) was found to be higher in RIR (74.68) and Mewari (74.08) as compared to Kadaknath (73.68) and Pratapdhan (73.35). The difference in moisture per cent between RIR and Mewari as well as between Kadaknath and Pratapdhan was found non- significant. In this study it was found that improved breeds RIR and Pratapdhan was better than desi breeds in egg quality traits.
