Abstract: The present study was conducted at the Animal Farm, Department of Animal Production, Rajasthan College of Agriculture and Udaipur to evaluate and compare internal egg quality traits among indigenous and improved chicken breeds. A total of 180 eggs were collected from four different chicken breeds, each 40 weeks old. The experiment included four treatments with three replications, each comprising 45 eggs. The treatment groups were as follows: T₁: Kadaknath, T₂: Rhode Island Red (RIR), T₃: Mewari, and T₄: Pratapdhan. The internal egg quality parameters measured included albumin weight, Haugh unit, and yolk weight. Results revealed that RIR exhibited the highest albumin weight (33.36g), followed by Pratapdhan (29.60g), Kadaknath (27.15g), and Mewari (25.41g), with statistically significant differences (p<0.05). The Haugh unit was also significantly higher in RIR (75.78) compared to the other breeds. While the difference between Kadaknath and Pratapdhan was minimal and statistically non-significant, Mewari recorded the lowest Haugh unit. In terms of yolk weight, RIR had the maximum value (17.70g), followed by Pratapdhan (15.99g), with Kadaknath (12.27g) and Mewari (12.03g) showing the lowest values. The findings indicate that improved chicken breeds, particularly RIR and Pratapdhan, possess significantly superior internal egg quality traits compared to indigenous breeds such as Kadaknath and Mewari.
