Explaining Global Turkey Biometric Diversity Through Principal Component Analysis.

ABSTRACT: The morphological diversity of the domestic turkey is still an open question in poultry research. For this reason, a meta-analysis with 97 reports from 28 morphometric characterization studies covering 15 different turkey genotypes was carried out in the present study. Biometric measurements and indices collected from the articles were used as independent variables in three principal component analyses. The highest variance explaining power was achieved in the analysis including only biometric indices, with more than 70% in the first two principal components for both sexes. The 'leg length', 'body mass', 'shape', and 'tarsus' indices were those with higher explanatory power, the latter two particularly so in females. In addition, 'head' was such a high variance explaining body region, espe
