Comparative study on some egg quality traits among four close-bred stocks of Japanese quail

Present study was conducted to evaluate some egg quality traits among four close-bred stocks (CBS) of Japanese quail at Avian Research and Training (ART) Centre, University of Veterinary and Animal Sciences, Lahore, Pakistan. For this, a total of 144 quail eggs having 36 eggs of each CBS (Major, Kaleem, Saadat and Zahid) were subjected to egg quality analysis. Data were recorded regarding egg weight (g), yolk index %, Haugh Unit and shell thickness (mm). Statistical analysis of data according to Completely Randomized Design through one-way ANOVA technique and comparison of mean using Duncan’s Multiple Range test revealed significant different among four CBS. Significantly higher Egg weight (g) and shell thickness (mm) was observed in CBS M as compared to K, S and Z. Better Haugh unit score was found in CBS Z as compared to rest of CBS. However, no significant effect of CBS on yolk index was also observed. It is concluded that four CBS of Japanese quail had significant effect on egg weight, shell thickness and Haugh unit score except yolk index.
