野猪与长白猪内脏器官的解剖学比较分析

选择人工繁育的健康纯种野母猪和长白猪各一头作为研究对象。观察其胃、胰脏、小肠、大肠、心脏、肺、肝、脾、肾等器官,对其长度、宽度和重量进行分析。结果表明：1）野猪胃、胰脏、十二指肠、空肠、回肠、盲肠、结肠的长度及宽度均大于长白猪,其重量也高,说明野猪通过自身寻觅饲料导致其消化器官的容积及重量增加,从而使其耐粗饲能力加强,而现代家猪因长期饲喂全价饲料导致消化器官的发育受到了一定的影响;2）野猪心脏、肺脏、肝脏、脾脏等其他内脏器官的长度和宽度均大于长白猪,说明野猪的血液循环系统和呼吸系统均强于长白猪,从而使其对环境的适应能力增强。

The Anatomical Comparison Between the Internal Organs of Wild Boar and Landrace Swine

A healthy purebred wild boar and a landrace swine are taken as the research objects. Observations are made on the stomach, pancreas, small intestine, large intestine, heart, lung, liver, spleen, kidney and other organs, and their length, width and weight are analyzed respectively.The results show that the stomach, pancreas, duodenum,jejunum, ileum, cecum and colon length and width of the wild boar are greater than the landrace swine＇s; and the weights of the wild boar＇s liver,pancreas,duodenum, colon ileum are greater than the landrace swine＇s.The increasing of the volume and weight of the wild boar＇s digestive organs is a direct result of their habitual behavior of looking for a variety of feed, making it capable of digesting coarse fodder. However, the digestive organs of modern pigs are influenced and weakened due to the fact that they are fed with regular fodder.The length,width and weight of the wild boar＇s heart,lung,liver, spleen and other organs are greater than the landrace＇s.The blood circulation and respiratory systems of the wild boar are stronger than the landrace＇s,which makes it more adaptive to the environment.
