Egg quality parameters are very crucial for the egg industry as egg configuration affects grading, price, hatchability, chick weight, and consumer preference. Current study was undertaken to assess and compare the egg quality parameters in 2 important Indian breeds Aseel and Kadaknath reared under backyard system. Different parameters of external and internal egg quality were measured. Biochemical parameters of egg yolk estimated were egg yolk cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), and triacylglycerol. Means for external characters of Aseel eggs viz., egg weight, egg length, egg width, shape index, shell weight, shell thickness, and shell ratio were 41.7 g, 5.16 cm, 3.85 cm, 74.75%, 4.65 g, 0.35 mm, and 11.23%, and corresponding values for Kadaknath eggs were 40.59 g, 5.13 cm, 3.79 cm, 74.02%, 4.28 g, 0.34 mm, and 10.61%, respectively. Average albumin length, width, height, and albumin index were 83.73 mm, 65.4 mm, 6.02 mm, and 9.26% for Aseel eggs and 82.27 mm, 64.80 mm, 5.52 mm and 8.52% for Kadaknath eggs, respectively. Mean values for yolk length, width, height and yolk index were 43.32 mm, 40.10 mm, 15.30 mm, and 38.30% in Aseel and 42.15 mm, 38.97 mm, 14.26 mm and 36.66% in Kadaknath breed, respectively. Mean values for egg yolk cholesterol, HDL, LDL, and triacylglycerol were estimated as 9.38, 1.74, 0.17, and 1.94 mg/g in Aseel eggs and 8.38, 1.84, 0.11, and 1.76 mg/g in Kadaknath eggs, respectively. Biochemical analysis revealed that egg yolk quality of Kadaknath eggs was comparatively better than Aseel eggs.
