The present study aimed at evaluating the effects of dietary selenium (Se) supplementation on egg morphometric and quality traits in Aseel chicken. In total, 84 adult molted Aseel hens, comprising 4 varieties (Lakha, Mushki, Peshawari, and Mianwali), were divided into 3 dietary treatments (organic at 0.30 ppm, inorganic at 0.30 ppm, and without selenium) with 7 replicates (1 bird in each) under randomized complete block design. Data were analyzed using factorial ANOVA and means were compared using Duncan’s Multiple Range Test. The results indicated greater egg length in Mushki and Mianwali, lower egg breadth in Lakha, the highest (p≤0.05) egg volume and surface area in Mianwali, and higher shape index in Lakha and Peshawari. Lakha had the highest Haugh unit and lower eggshell thickness with and without membrane than the other three varieties. Interaction of Se sources and Aseel varieties exhibited the highest (p≤0.05) egg volume and surface area in Mianwali variety when fed on organic Se supplemented diet. Similarly, the interaction showed the highest eggshell thickness with membrane in Peshawari and without membrane in Mianwali when fed on inorganic Se supplemented diet. From the findings, it can be concluded that egg physical characteristics of Mianwali variety hens can be improved by the supplementation of Se-enriched yeast, as an organic Se source, in the diet.
