Determination and Correlation Analysis on Body Size Traits and Slaughter Performance of Kirin Chicken(Frizzle Chicken)

In order to study the meat development value of anti-heat stress species-Kirin chicken(Frizzle chicken),12-weekold Frizzle chicken was used to measure their body size traits and slaughter performance indexes and then studied these data with correlation and regression analysis.The results showed that keel length(12.05cm)and shank length(8.70cm)of male 12-week-old Frizzle chickens were significantly higher than those of female chickens(10.17,7.47cm)(P0.05).The live weight,carcass weight,semi-eviscerated weight,eviscerated weight and the leg muscle of male 12-week-old Frizzle chickens were significantly higher than those of female chickens(P0.05),abdominal fat weight(27.22g)and sebum thick(4.38mm)were significantly lower than those of female chickens(35.33 g,5.12mm)(P0.05),other indicators were no significant differences(P0.05).There were highly significant or very highly significant correlations between the slaughter performance and body size in Frizzle chicken.The regression equation of related indicators was identified.This conclusion provided a certain theoretical reference to predict slaughter performance indicators through a living body size measurements and contributed to the genetic breeding process of Frizzle chicken.
