Abstract

A study was conducted to determine the egg quality characteristics of three breeds of Philippine native chickens and their crosses. A total of 108 existing experimental chickens at the National Swine and Poultry Research and Development Center in Tiaong Quezon were used. Eggs were collected three times per week for the month of June 2015 with a total of 150. All eggs were examined for external parameters such as egg weight, egg size, and egg shell color as well as internal parameters such as yolk weight, yolk color, albumen weight, egg shell thickness and egg shell weight. Significant differences were observed in egg shell weight, egg shell color, egg yolk weight, egg yolk color, yolk to albumen ratio and yolk percentage parameters (P<0.05). On the other hand, other parameters such as egg weight, egg length and egg width were not affected by the breed nor the mating combination (P>0.05). Furthermore,based on the Pearson correlation coefficients, positive correlations were found between egg weight, egg length, egg width, egg shell thickness, egg yolk color and egg albumen weight (P<0.01) while egg weight is negatively correlated with derived egg quality parameters. Joloanon male mated to Banaba female produced the highest egg quality since all important egg quality parameters in hatchability and consumer preferences are positively correlated to egg weight. Furthermore, egg weight alone can be a basis of egg quality because of its positive correlation to most egg quality parameters.
