The interior quality of egg in four outbred F1 populations of Japanese quail

This study was conducted to evaluate the interior quality of egg in four outbred F1 population of Japanese quail. Two hundred Japanese quails were used in this study. They were grouped into four lines based on their mating systems, i.e. male brown quail 1 and female black quail 2 (BL1), male brown 2 and female black 1 (BL2), male black 1 and female brown 2 (LB1), and male black 2 and female quail 1 (LB2). Each line consisted of 50 quails. Eggs were collected at the age of 10 weeks. Interior egg characteristics were tested for three consecutive days. They were height, weight, and index of albumen; weight, height, and index of yolk, yolk color score, and Haugh unit (HU). The data was analyzed using one-way analysis of variance (ANOVA), and pairwise differences among lines were performed using Duncan's multiple range test (DMRT). The results showed that albumen weight and yolk height were significantly different among lines (P<0.05). Better albumen weight and yolk height were found in LB populations. Other traits were not different among outbreeding populations. It can be concluded that the best interior qualities of egg were produced by LB quail populations.
