对雌雄之间的测量性状和生长速度进行了比较研究，结果表明，雌雄之间体长与身高、体重与体长的比值存在极显著差异，体长与头长、尾长与尾高、头长与鼻长、头长与眼径的比值无显著差异，在相同的养殖条件下，雌雄之间生长速度无明显差异，小于170g；雌性生长速度明显快于雄性，体重在170~800g之间，当体重超过800g时，雌性生长速度减慢，雄性生长开始快于雌性，一般1 kg以下雌性大于雄性，1 kg以后雌性大于雄性。
The measured characters and growth speed were studied comparatively between the male and female S.chuatsi.The results indicated that there were very significant discrepancies on the rate of body length to height and the rate of body weight to body length between the male and female S.chuatsi.There was no discrepancy on the rates of body length to head length,trail length to trail height,head length to snot length,head length to eye diameter.Under the same culturing condition,there was no apparent discrepancy on the growth speed between the male and female S.chuatsi that was less than 170 g;The growth speed of the female was obviously faster than the male that was from 170 g to 800 g.When the body weight was more than 800 g,the growth speed of the female slowed down,and the male began to grow faster than the female.In generally,the female is bigger than the male under 1kg,and smaller after 1kg.
