东北民猪胸、腹、盆腔内器官生长发育规律的研究

Study on the Law of Organs Growth in Thoracic,Abdominal and Pelvic Cavity of Northeast Min Pig

选用东北民猪，从初生到6月龄分7个月龄段，计28头猪，每月龄屠宰4头（公、母各2头）。进行胸、腹、盆腔内各器官的生长发育规律的测定。测定结果，母猪子宫角发育速度，为各性状之首，阴道重量也为增重速度较快性状。公猪林囊晚在各性状中增重速度最快。5～6月龄是增长旺盛期。胸、腹腔内各器官均在初生、一月龄和二月龄阶段增重最快，而其余阶段增重较慢。

To select 28 Northeast Min Pig, In which the age is from newborn to sixth month,Which was divided into seven periods,and slaughtered four in each period (2 males and 2 females). Then,to determine the law of the growth rate of each organ in the body. The result is that:the growth rate of u-terine horn in the sow pig is the fastest,and the growth rate of vagina is faster than the others,too. the gainin weight of seminal vesicle in b0ar pig is the fastest among the organs. The peak growth perfod of reproductive organs is from fifth month to sixth month. The gain in weight of each organ in thoracic cavity andabdominal cavity is the fastest at newborn,first month and second month,and the gain in weight of organsis s1ower at the other stages.
