Abstract:
Objective To measure the organ weight and body weight of outbred Wuzhishan mini-pigs (WZSP), and calculate the organ coefficient and the linear and multiple linear regression equations between body weight and major organ weights. Methods 30 common WZSP (16 males and 14 females) were chosen,the body weight and 7 organ weights were determined, and the organ coefficients were calculated. The organ coefficients between males and females were compared. The correlation and regression analysis was performed using the SAS software. Results The coefficient of heart had remarkably significant difference between males and females (P<0.05).The linear analysis showed that there were apparent linear correlations between body weight and all the organ weights except for the stomach of males and the lung of females.The weights of liver and kidney showed great influence on the body weight of males, while the body weight of females relied on the weights of heart, liver and kidney greatly. Conclusion Differences of organ coefficients are not significant between males and females,and there are linear relationships between body weight and some major organ weights.
