Comparative Analysis of Organ Index of Wuliangshan Silky Fowl

Abstract

Abstract: 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.
