甘孜州藏猪内脏器官发育特征研究
The Characteristics of the Development of the Visceral Organs of the Tibetan Pig in Ganzi of Sichuan

以甘孜藏族自治州放牧藏猪为研究对象，从增加体质量组织结构2个方面分析研究了藏猪内脏器官的生长发育特征.结果表明：甘孜州藏猪内脏器官的生长发育表现出与高海拔、缺氧、寒冷、自寻觅食等恶劣环境相适应的特征，具有独特的发育规律，各内脏器官成熟顺序从早到晚依次为肺脏、胰腺、小肠、肾脏、肝脏、心脏、胃、大肠；胰腺的生长与机能分化发育同步，至7月龄时基本成熟；肝、胃、小肠的生长高峰期均在3月龄以前，肝的组织结构在7月龄时基本稳定，胃和小肠的组织结构到10月龄时基本稳定；大肠至13月龄尚未达到生长高峰.
In a study reported in this paper, the development characteristics of the visceral organs of the Tibetan pig in Ganzi Prefecture of Tibetan Autonomous Region were investigated from the respect of their weight gain and organization structure. The results showed that the Tibetan pig had to adapt to the harsh environments-high altitude, hypoxia, cold and self-foraging-in Ganzi, the growth and development of its visceral organs were quite unique in character. Of its visceral organs the lung matured the earliest, followed in order by the pancreas, the small intestine, the kidney, the liver, the heart, the stomach and the large intestine. The growth of the pancreas occurred synchronically with its functional differentiation and this organ matured when the pig was, 7 months old. The growth peaks of the liver, the stomach and the small intestine appeared before the pig was 3 months old, and the organization structure was basically steady when the pig was 7 months old. The organization structures of the stomach and the small intestine were stabilized when the pig was 10 months old while the large intestine kept growing at 13 months
