Correlation and Regression Analysis on Body Weight and CombSize of Different Crossing High-quality Chilled Chicken
摘要
Abstract
Crossbreeding combinations of high quality chilled chicken were initially screened by comparing body weight and comb size.The efficiency of breeding was improved through correlation analysis between comb trait and body weight and establishing the optimal regression equation.Three combinations of high quality chilled chicken at 63 d were used to measure its body weight and comb traits, and then correlation and regression analysis were conducted using SPSS16.0.The multivariate regression equations between body weight and comb traits were built by using stepwise regression.The results were as follows.The body weight at 63d of female of three combinations weighed more than 1.8kg, and males weighed more than 2.2 kg.The chicken wattle circumference, total chicken circumference, chicken wattle area and total area of big comb males for cross combination of chilled chicken line 1 (ABC) were significantly higher than that of other combinations.The average color R of ABC big comb males was significantly higher than that of the other combinations.Chicken wattle chromaticity level of ABC big comb males was significantly higher than that of males in cross combination of chilled chicken line 2(ABD) and male and female in AEB.The comb chromaticity level of ABC big comb males was significantly higher than that of ABC, ABD female and male and female in cross combination of chilled chicken line 3(AEB).There was extremely significant positive correlation between body weight at 63 d and chicken wattle circumference (comb + chicken wattle), chicken wattle area, comb area, total area (comb + chicken wattle) (P<0.01), and the correlation coefficient were between 0.579 and 0.753, with the total circumference (comb+chicken wattle) correlation coefficient being the largest, 0.753.The body weight change can be accurately assessed by measuring total comb circumference and total comb area.关键词
