Correlation analysis of live measurable traits and sebum weight in Wenchang chicken
摘要
Abstract
The purpose of this study was to explore the relationship between live measurement traits and sebum weight in Wenchang chick-en.In order to explore the feasibility of indirectly selecting sebum weight by measurable traits in vivo of Wenchang chickens,60 120-day-old Wenchang chickens,half males and half females,were selected,in this study,to measure their body weight,body oblique length,chest width,chest depth,keel length,pelvic width,shin length,shin circumference,pectoral muscle thickness,sebum thickness,and sebum weight.SPSS 26.0 was used to perform correlation analysis,path analysis and stepwise linear regression analysis of those indexed.The results showed that the sebum weight of the Wenchang roosters was extremely significantly positively correlated with their body weight,pectoral mus-cle thickness and sebum thickness(P＜0.01),and body oblique length(P＜0.05),among which the most significant correlation was that between sebum weight and pectoralis muscle thickness(R=0.687),followed by that between sebum weight and body weight(R=0.685).There was extremely significant positive correlation between sebum thickness and body weight,body oblique length,pectoral muscle thickness and sebum thickness of the hens(P＜0.01),among which the highest correlation coefficient was that between sebum weight and body weight(R=0.857),followed by that between sebum weight and sebum thickness(R=0.630).Body weight mainly affected sebum weight of the males and famales through direct effect,body oblique length mainly affected sebum weight of the rosters through indirect effect,and shin length mainly affected sebum weight of the hens through indirect effect.The optimal regression equations between live measurable traits and sebum weight of Wenchang chickens herre were Ysebum weight=396.649+42.279Xpectoral muscle thickness+0.187Xbody weight+1 213.592Xsebum thickness-36.516Xbody oblique length,Ysebum weight=193.928+0.264Xbody weight-61.334Xshin length,respectively.关键词
