Egg Quality Parameters Evaluation of Indigenous and Sasso Chicken in Sidama Region, Ethiopia

Abstract

A study was conducted at Aleta Wondo district of Sidama Region to evaluate quality parameters of eggs collected from indigenous and Sasso chickens reared under a traditional management system. About 100 eggs from each chicken type were collected from households who keep indigenous or Sasso chicken. Eggs were transported to Hawassa university poultry farm for quality parameters analysis. External and internal egg quality analysis was done according to laboratory procedure. Collected data was analyzed using SAS (Version 9.0). Results indicated that eggs collected from Sasso chicken showed superiority over indigenous chicken’s eggs for egg weight, egg length, egg width, shell weight, shell thickness and surface area. There is no significant difference on shape index and shell percentage of eggs collected from indigenous and Sasso chickens. Shape index recorded was 72.66 and 74.04 for indigenous and Sasso chickens respectively. Albumen weight was statistically higher for eggs collected from Sasso chickens (P<0.0001). Eggs from indigenous chickens have superiority over Sasso’s eggs for yolk ratio, Haugh Unit and yolk albumen ratio. However, there is no significant variation on albumen height, yolk weight, yolk height, yolk color, yolk diameter and yolk index. It can be concluded that Sasso chicken produce heavier eggs than indigenous chicken. Yolk related parameters are similar for indigenous and Sasso chicken eggs produced at traditional management system.
