辽宁产中国林蛙油、卵产量及蛋白质含量动态分析

Dynamic Analysis of Oviduct,Egg and Protein Contents in Chinese Linwa (Rana chensinensis)Grown in Liaoning Province

研究1～3龄中国林蛙（Ranachensinensis）哈土蟆油、卵产量以及油、卵和去内脏躯体中粗蛋白含量。结果表明：3龄蛙的含油量和绝对含卵量显著效高，而相对含卵量2龄蛙最高。粗蛋白含量在不同蛙龄、不同部位间都有差异，不同部位的变化趋势也不一样，其中印中蛋白质含量最高，油中蛋白质含量相对较稳定。去内脏躯体中也有很高的蛋白质含量，且雌雄躯体间无明显差别。越冬前后相比较，油的产量及油中蛋白含量都无明显差异，卵的产量越冬后显著较高．卵中蛋白含量差异不显著。

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.
