| 摘 要： | 猪的心、肝、肺、脾、肾五脏器的发育早晚直接影响着其它部位的生长发育的快慢.运用异速生长方程分析了舍饲型合作猪内脏器官的生长发育规律.结果表明：肝脏和肺脏的增重迅速,肾脏和心脏次之,脾脏较慢;肺脏和肾脏的相对生长速度较快,其次为心脏和脾脏,肝脏较慢;各内脏器官占体重百分比为：肝脏＞肺脏＞肾脏＞心脏＞脾脏;异速生长方程拟合的内脏器官生长强度为：心脏（b=1.120）＞脾脏（b＝0.974）＞肺脏（b=0.973）＞肾脏（b=0.9520）＞肝脏（b=0.726）,心脏属于晚熟器官,脾脏、肺脏和肾脏属于中熟器官,肝脏属于早熟器官.为保护合作地方品种,进一步开发利用优良品种提供了数据参考.

| Abstract: | The allometric equation was used to study the regularity of internal organ＇s growth and development about Hezuo pig. The results showed that： weight gain of liver and lung was the fastest, followed by kidney and heart,spleen was the slo- west. The relative growth speed of lung and kidney was the fastest, followed by heart and spleen, liver was the slowest. Ac- counting for percentage of body weight of internal organs： liver〉lung〉kidney〉heart〉spleen. The sequence of growth inten- sity by allometric equation was：Heart （b=l. 120）〉spleen （b=0. 974）〉lung （b=0. 973）〉kidney （b=0. 9520）〉liver （b= 0. 726）. Heart belonged to late-maturing organ, spleen,lung and kidney belonged to medium organ, liver belonged to precocious organ. The study provided data reference for protecting local breed and further developing excellent breed. |
