Cluster Analysis of Laying Performance and Production Area Ecology of 11 Chicken Breeds
摘要
Abstract
The multivariate statistics analysis of laying performance and ecological characters were carried out on 11 Chinese native chicken breeds by the methods of principal component analysis and cluster a-nalysis. The results showed that 11 native Chinese breeds could be divided into large and small type on the basis of laying performance.and the results of multivariate statistics analysis of (0 indexes showed that 3 eigenvalues were selected as the 3 major components accounting for 94. 99% of the total) before the principal component analysis. The 11 Chinese native chicken breeds can be divided into high elevation type and low elevation type according to 3 principal component values of each breeds, which suggested that the ecological factor was also an important basis on the breed region classification.关键词
