Abstract: Translucent egg has become a focus of attention in egg production in recent years.In order to explore the variation rule of translucent eggs and its influence on egg quality,500 Jining Bairi chickens and 500 Wenshang Luhua chickens with the same age and feeding environment were selected in this study.60 eggs of each of the two varieties were collected,and the changes of translucent eggs at 0,1,2,3,4,12,24 h and 3,5,7 d were recorded,and the proportion of translucent eggs was calculated.At the same time,200 eggs of each of the two varieties were collected.After being placed for 3 d,30 normal eggs of each variety and 30 fourth-grade translucent egg were selected for egg quality detection.The results showed that the translucent egg rate of Wenshang Luhua chickens was lower than that of Jining Bairi chickens.Translucent eggs began to appear after 2 h of egg production,4-12 h was the high incidence period,12 h-3 d was the aggravation period.During 3-7 d,normal eggs would no longer change to translucent eggs,but low-level translucent eggs would change to high-level translucent eggs.There were no significant differences in shell thickness,eggshell ratio,egg yolk color and harrington units between translucent eggs and normal eggs of two varieties (P>0.05).The albumen height of normal eggs of Jining Bairi chickens was higher than that of translucent eggs (P<0.05),but the difference between translucent eggs and normal eggs of Wenshang Luhua chickens was not significant (P>0.05).In summary,time was an important factor affecting the production of translucent eggs.Different varieties of eggs had different translucent egg production rates,and translucent eggs had a certain effect on egg quality.

Key words: Wenshang Luhua chickens; Jining Bairi chickens; translucent egg; egg quality
