Body Measurement,Slaughter Performance,Egg Quality of Adult Pu'an Panjiang Black-bone Chicken and Their Correlations
摘要
Abstract
[Objective]The body measurement,slaughter performance,egg quality of Pu'an Panjiang black-bone chicken,and the correlations between these traits were investigated to provide a theoretical basis for genetic improvement and systematic breeding of Pu'an Panjiang black-bone chicken.[Method]The body measurement,slaughter performance and egg quality of 60 randomly selected adult Pu'an Panjiang black-bone chickens(30 cocks and 30 hens)with 300 day old and 60 produced egg during the same period,and the correlations between these traits were analyzed.[Result]The body slope length,keel length,chest depth,chest width,shank length,shank girth,live weight,dressed weight,semi-eviscerated weight,total eviscerated weight,semi-eviscerated rate and total eviscerated rate of adult Pu'an Panjiang black-bone cocks were 21.69 cm,12.76 cm,9.74 cm,9.39 cm,11.59 cm and 4.51 cm,2 585.47 g,2 330.53 g,2 127.60 g,2 027.67 g,82.31%and 78.45%significantly or very significantly higher than those of adult Pu'an Panjiang black-bone hens,respectively.The slaughter rate of adult Pu'an Panjiang black-bone cocks was 90.13%,and lower than adult Pu'an Panjiang black-bone hens very significantly.The body slope length was positively and very significantly related to shank girth in cocks.The body slope length and chest width were positively and very significantly related to the slaughter indexes(live weight,dressed weight,semi-eviscerated weight and total eviscerated weight)in hens.The average egg weight,egg shape index,yolk rate and Haugh unit were 48.53 g,1.38,32.68%and 64.70 respectively.The egg weight was positively and very significantly related to egg shell thickness,yolk weight and shell weight,and negatively and very significantly related to yolk rate.The egg shell thickness was positively and very significantly related to shell weight,shell strength and shell rate.The egg shell weight was positively and very significantly related to egg shell rate and negatively and very significantly related to yolk rate.The yolk weight was positively and very significantly related to yolk rate,egg white height and Haugh unit.[Conclusion]The body measurement and slaughter performance of adult Pu'an Panjiang black-bone cocks are better than those of adult Pu'an Panjiang black-bone hens.The body slope length,chest width and shank girth are the key body measurement indexes influencing slaughter performance.The shell weight,shell thickness and yolk rate can be used as the indirect breeding indexes in egg weight.The egg weight,shell weight and yolk weight can be used as the indirect indexes for breeding of yolk rate.关键词
