雌性五指山猪生殖器官生长发育的研究

五指山猪是中国特有的小型猪种,是作为人类实验模型的首选动物之一.为给五指山猪的品种保护和合理开发利用提供基础资料,试验采用解剖学和统计学方法,对不同日龄雌性五指山猪卵巢、输卵管和子宫进行了解剖测量,并对其数据进行了分析处理,探讨了其生长发育特点.结果表明,五指山猪卵巢长径、短径及厚度增长与日龄呈线性相关,其重量增长与日龄呈指数相关,而其指数随日龄增加呈先减后增的趋势;五指山猪输卵管长度和管径的增长与日龄呈线性相关,重量增长与日龄呈指数生长;五指山猪子宫体长度的生长与日龄呈线性生长模式,子宫体生长发育强度在70~110 d之间,其长度在1.093~11.557 cm之间.

Study on Growth and Development of Reproductive Organs in Female Wuzhishan Swine

Wuzhishan swine is an unique small breed in China which is one of the first experimental model animals for human beings.Anatomical and statistical methods was used to provide basic information for the protection,rational development and utilization of Wuzhishan swine variety.The ovaries,fallopian tubes and uterus of different age female Wuzhishan swine were dissected and measured,the data was analyzed and its growth characteristics were discussed.The results showed that the ovarian long diameter,the short diameter and the thickness increase of Wuzhishan swine were related with age linearly and its weight increase was exponentially related with age,while the index increases with age presented the characteristic of first decrease and the following increase;The length of Wuzhishan swine fallopian tube and the growth of diameter was related with age linearly,its increase of weight presented exponential growth;The growth of Wuzhishan swine uterus length with age presented linear growth pattern.The intensity of uterine growth and development was 70 to 110 d,and its length was 1.093 to 11.557 cm.
