【摘要】：选取130 d马站红鸡母鸡70羽、公鸡20羽,测定其体质量与体尺指标,对该70羽母鸡开产后第31~115天的产蛋量、蛋质量进行记录,并测定第110~115天共计92枚鸡蛋的蛋品质,在此基础上应用典型相关分析原理与主成分分析方法对体质量、体尺与产蛋性能及蛋品质各指标进行分析。结果表明,体质量(y)与体斜长(x_1)、龙骨长(x_2)、胸深(x_3)、胸宽(x_4)、胫长(x_5)、胫围(x_6)、骨盆宽(x_7)、蛋质量(x_9)呈极显著相关(P0.01);蛋质量与体质量、体斜长、胫围呈极显著相关(P0.01),与蛋黄颜色、蛋白高度呈显著正相关(P0.05),与蛋黄比率呈极显著负相关(P0.01);蛋壳强度与蛋壳厚度呈极显著正相关(P0.01),哈氏单位与蛋白高度呈极显著正相关(P0.01);最佳回归方程为y=-2.291+0.047x2+0.137x4+0.090x5+0.272x6+0.115x7;体质量、体尺与产蛋性能10个指标综合成6个主成分,累计贡献率达87.337%。
[Abstract]:A total of 70 hens and 20 male hens were selected for 130 days. The body weight and body size of the hens were measured. The egg production and egg quality of the 70 hens were recorded on the 31o115 days after delivery, and the egg quality of 92 eggs was determined on the 110- 115th day. On this basis, the body mass, body size, egg performance and egg quality were analyzed by using the principle of canonical correlation analysis and principal component analysis. The results showed that there was a very significant correlation between body weight and body weight, lean length, tibial circumference, tibial length, body weight, lean length, tibial circumference, and yolk color, P0.01a and yolk color, and the color of yolk and yolk, and the weight of egg and body weight, the length of body, tibial circumference, yolk, and yolk color. There was a significant positive correlation between protein height and egg yolk ratio (P0.01A), a very significant positive correlation between eggshell strength and eggshell thickness (P0.01A), a very significant positive correlation between egg shell strength and egg shell thickness (P0.01G), and a very significant positive correlation between protein height and protein height (P0.01C). The best regression equation was y1-2.291 0.047x2 0.137x4 0.090x5 0.272x6 0.115x7. The body size and the 10 indexes of laying performance were synthesized into 6 principal components, and the cumulative contribution rate was 87.337%.
