长爪沙鼠的生理及行为研究初探

Physiology and Behavior of Mongolian Gerbils

观察40只长爪沙鼠的生活及生产行为系列特征,测定了20只长爪沙鼠血液生理生化指标20项。长爪沙鼠的行为学特征研究表明,长爪沙鼠的食性广泛,部分长爪沙鼠有囤积食物行为,饮水少,耐干旱;性情温顺,行动敏捷,喜欢群居。在繁殖时期,长爪沙鼠一雌一雄制交配行为较为明显。在长爪沙鼠离乳时合笼,能和睦生活、交配、产仔、哺乳。成年后合笼,则雌鼠可能拒绝交配,如果在饲养过程中雌鼠或雄鼠死亡,则不容易再给存活的种鼠配对。同一长爪沙鼠种群里,在部分血液生化指标的比较中,UA,CHO,TG,ALP,GOT和LDH的测定值存在显著差异,其中UA,GOT和LDH的含量雌性高与雄性。血液生理指标测定表明,雌雄个体之间在,WBC,RBC,PLT,MCHC,WS,WM和WL上存在显著差异,其中,RBC,WM和WL的含量雌性高于雄性,其余无显著差异。结果表明:长爪沙鼠的繁殖宜采用一雌一雄方式,离乳时合笼。性别对其部分血清生化指标和血液生理指标有显著影响。

Forty Mongolian gerbils＇ living and reproductive behavioral characteristics were observed, and 20 parameters of 20 Mongolian gerbils＇normal physiological and biochemical values were determined. The results show that Mongolian gerbils can eat a majority of food, Some of them like hoarding food with little drinking and drought tolerance. They are docile, move quickly and often live in group. During breeding, each Mongolian gerbil mates with only one partner. Mongolian gerbils can harmoniously live, mate, breed and suckle if they are caged together after being weaned. Female Mongolian gerbils may refuse to mate if they cohabitate after growing up. A Mongolian gerbil is difficult to mate if its partner has died. In the same population of Mongolian gerbils, there are no significant differences in their physiological parameters except UA, CHO, TG, ALP, GOT, LDH, while the UA, GOT and LDH of female Mongolian gerbils are higher than those of the male. And female gerbils is higher than male in UA, GOT, LDH, RBC, WM and WL It is concluded that we should let a female Mongolian gerbil live with only one female to breed and some biochemical and physiological indicators are significantly impacted by sex.
