无量山乌骨鸡器官指数比较分析

Comparative Analysis of Organ Index of Wuliangshan Silky Fowl

内脏器官是消化和吸收各类营养物质的主要区域,是身体的功能性器官,对于家禽的生长发育起着极其重要的作用.通过对40只五月龄无量山乌骨鸡器官指数的比较分析得出:公鸡的活重、肺脏重、心脏重、性腺重、肝脏重均极显著高于母鸡(P<0.01),而肌胃重则显著高于母鸡(P<0.05);公鸡的性腺、肺脏和心脏指数均显著高于母鸡(P<0.05),而肝脏和肌胃指数显著低于母鸡(P<0.05);公鸡的心脏和性腺指数均与活重呈极显著正相关(P<0.01),母鸡的心脏、肾脏、肺脏和腺胃指数均与活重呈极显著正相关(P<0.01),肝脏和腺胃指数与活重呈显著正相关(P<0.05).内脏器官的重量和器官指数在一定程度上反映了动物机体的机能状况,对于理论研究和生产实践有重要的指导意义.

Internal organs are the functional organs of the body that play an important role in digestion and absorption of various nutrients and body growth performance and development of poultry.The organ indexes of 40 Wuliangshan black-bone chickens at the age of five months are compared with the internal organs of hens.The results showed significantly higher live body weight,lungs,heart,gonads and liver weight of cocks than those of hens(P<0.01).Muscle stomach weight is significantly higher than that of hens(P<0.05).The gonads,lungs and heart weight indexes of cocks are significantly higher than those of hens(P<0.05).The liver and gastric indices are significantly lower than those of hens(P<0.05).Both heart and gonads weight indexes are significantly positively correlated with live weight and the weight indexes of heart,kidneys,lungs and glandular stomach are significantly positively correlated with live weight(P<0.01).Moreover,liver and adeno gastric indices are significantly positively correlated with live weight(P<0.05).The weight and organs indexes of internal organs reflect the function of animal body to a certain extent,and have important guiding significance for metabolic activity and production practices.
