RESUMO
Oviduct,egg and protein contents of 1~3 years old Rana chensinensis were studied. Results showed thatthe oviduct content and the absolute value of eggs were significantly higher in 3-year o1d frogs,While the rela-tive va1ue of eggs was highest in 2 years old frogs- Crude protein content varied in different aged group as wellas in different parts of the body,with eggs containing the highest amount. Protein in oviduct was comparative-ly consistant. Protein content in deviscerized body was rather high with no significant difference between maleand female. Frogs before and after hibernation have essentially similar oviduct and protein content,but eggcontent were significantly higher after hibernation. Protein content in eggs was not notab1y changed.
