康县太平鸡体尺性状与屠宰性状的测定及相关性分析OA

This study aims to explore the body size traits,slaughter traits and the correlation between the Taiping chickens in Kang County.We took 40-week-old healthy Taiping chickens as the research object,measured their body size traits and slaughter traits,and analyzed the correlation between all the measured traits.The results showed that the oblique length of the 40-week-old Taiping chicken was 21.87 cm,the keel length was 10.70 cm,the shin length was 9.01 cm,the shin girth was 4.32 cm,the chest girth was 28.05 cm,the chest depth was 10.65 cm,the chest width was 6.82 cm,and the pelvis The width is 7.65 cm;the live weight before slaughter is 1 920.7 g,the carcass weight is 1712.5 g,the half eviscerated weight is 1533.4 g,the whole eviscerated weight is 1314.3 g,the chest muscle weight is 277.6 g,and the leg muscle weight is 395.5 g.The slaughter rate is 89.1%,the evisceration rate is 79.3%,the full eviscerated rate is 67.8%,the chest muscle rate is 20.8%,the leg muscle rate is 27.1%,the heart weight rate is 12.2%,and the abdominal fat rate is 3.0%.Taiping chicken body ob-lique length,chest girth,shin length,shin girth and carcass weight,eviscerated weight,half eviscerated weight,and leg mus-cle weight were significantly positively correlated(P<0.01).This study shows that Taiping chickens have good meat per-formance,low fat,body oblique length,chest circumference,shank length,and shank circumference can be used as indicators for slaughter performance of Taiping chickens.
