食物蛋白含量对雄性长爪沙鼠社会行为和某些生理特征的影响

为确定食物蛋白对长爪沙鼠行为和生理特征的影响,我们采用两种不同蛋白含量(9% 和27% )的食物饲喂不同年龄的雄性长爪沙鼠,测定了不同食物条件下长爪沙鼠的体重、睾丸重、脾脏重、血清抗体、社会行为和气味吸引力等指标。结果发现,食物蛋白含量没有影响长爪沙鼠的社会行为、生理特征及幼体气味的选择,但对成体气味的被选择程度影响显著,提示食物质量与其配偶选择过程相关联。

Effects of dietary protein content on social behavior and some physiological properties in male Mongolian gerbils (Meriones unguiculatus)

In order to determine the effects of dietary protein content on the physiology,odor attraction,and social behavior in Mongolian gerbils (Meriones unguiculatus), we fed juvenile and adult male Mongolian gerbils with high and low protein content food. Body mass,spleen mass,testis mass,serum antibody levels,social behavior and odor attractiveness were measured. There was no significant difference in physiological function and social behavior between the groups which fed with high and low protein content food. The odor attractiveness was different between adult animals fed different protein diets, impling that food quality was related to animals'mate choice.
