Evaluating the quality of indigenous chicken eggs in Gena Bossa district of Dawro zone, South Ethiopia

Abstract

This study was carried out in the Gena Bossa district to evaluate the quality of indigenous chicken eggs in different agro-ecology and education levels of chicken producers. A total of 108 fresh eggs were collected from randomly selected 36 households for the determination of egg quality parameters and three eggs from each household, 36 eggs from each Agro-ecology, and 27 eggs from each education level of farmers collected. Eggs collected from highland agro-ecologies had the highest egg weight (43.94 ± 0.42g), shell thickness (0.54 ± 0.01mm), albumen weight (23.31 ± 0.40g), and shell weight (5.25 ± 0.73g). Lowl and eggs had the highest yolk color score (8.65 ± 0.14). Eggs collected from primary second cycle educated farmers had the highest egg weight (44.41 ± 0.48g), albumen height (5.17 ± 0.17mm), Haugh unit score (75.34 ± 1.41%), yolk height (15.58 ± 0.33), albumen weight (23.65 ± 0.46g), and shell weight (5.33 ± 0.08g). Except for shell thickness (0.54 ± 0.11mm) all egg quality parameters were lowest for eggs collected from illiterate farmers. Egg weight was most appropriate in primary first cycle and primary second cycle interactions with respective highland and midland agro-ecologies. However, shell strength was most appropriate in the interactions of highland agro-ecology with illiterate education level. The combinations of primary second cycle with highland agro-ecology was most appropriate than other interactions for albumen weight. Depending on this conclusion, it will be better to investigate further studies on factors affecting internal and external qualities of the eggs in the study area.
