摘 要:本文观测88条乌梢蛇((?)dhumnades)肥满度和5种器官与组织生物量的季节变化,以及蛇体9个部分含能量的比较。春季的肥满度最低,仅为年均值的87.8%,冬眠前夕或11月的水平最高,为年均值的114.5%。皮肤、肌肉生物量与体系的比重无明显的季节变化,二者的年均值,分别为体重的16.4%(SD=0.6)与59.4%(SD=3.2),其含水量为64.1%(SD=5.9)与70.3%(SD=1.7)。心脏、肝脏、体脂生物量的年均值为0.31%、2.2%与4.3%;三者生物量均以春季最低,分别为体重的0.25%,1.7%与2.1%。但生物量最高季节却不同,心脏在春季达体重的0.36%,肝脏在冬季占体重的2.8%。体脂在秋季占体重的5.8%。5月份,每条蛇体的能量为5.42Kcal/g(SD=0.08)。器官与组织含能值水平以体脂最高6.76Kcal/g(SD=0.31);蛇皮最低,仅5.12Kcal/g(SD=0.03)。The authors report the seasonal changes of the corpulence coefficients, the masses of five organs and the potential energy of nine sections of the snakes through.the measurement of 88 samples of Zaocys dhumnades. The corpulence coefficient is at its lowest level in spring (87.8% of the average level of the year ) but at its highest level in November (114.5% of the average level of the year). The ratios of the mass of skin and muscle to the body weight do not change obviously with the season. So far as the average value of the year, the mass of skin is 16. 4% of the. body weight(SD=0.6) and the water content of skin is 64.1%(SD=5.9) while the mass of muscle is 59. 4%(SD=3.2) and the water content of muscle is 70.3%(SD=1.7). The yearly average masses of heart, liver and body fat are ,respectively , 0.31%, 2.2% and 4.3% of the body weight. But these masses are at their lowest level in spring, the corresponding values being 0.25%, 1.7% and 2.1%. The heart gets its highest mass in summer(0.36% of the body weight) while the liver in winter (2.8% of the body weight)and the body fat in autumn(5.8% of the body weight). The average energy value of the full body of the snake is 5.42Kcal/g(SD = 0.08) while that of body fat is 6. 76Kcal/g(SD=0.31) and that of skin is 5. 12Kcal/g(SD=0.03).
