Study on the Germplasm Characteristic of Piao Chickens

In this study, 100 Piao chickens were used to investigate the germplasm characteristic. The results showed that:Piao chicken has its own unique physical characteristics. The weights of cock and hen were 2300.64g and 1815.75g, respectively, at the age of 43 weeks. The chest width and keel length in cocks were significantly higher than those in the of hens (P0.05). The body length, tibia length and chest depth in cocks were extremely higher than those in the hens (P0.01).The dressing percentage were 90.24% and 91.41% respectively for cocks and hens, while eviscerated weight percentage were 69.52% and 69.22%, in addition to the breast muscle rate of hens was significantly higher than that of cocks (P0.05). The otherslaughter performance indicators in hens were lower than those in the cocks. The weight of heart, lungs and intestines in cocks was extremely higher than that in the hens (P0.01), and the hens had higher organ index of liver, kidney and gizzard compared with cocks. There was significant correlation between body size traits and carcass performance in piao chickens. The result of this study can provide a theoretical basis for breeding in Piao chicken.
