Background and Objective: Earlobe, a head furnishing trait, is a non-putative trait in Peluca hen ('naked-necked' hen), a local breed from Guatemala. The objective of this study is to determine if presence or absence of earlobe is linked to a body linear trait. Materials and Methods: Quantitative data collected on 311 mature hens belonging to Peluca breed were subjected to analyses for two different phenotypic subsets according to presence/absence of earlobes (212 with earlobes and 99 without earlobes). Measured morphometric traits were 18: Weight, Perimeter, Length, Width and Height of Body, Wing Length, Leg Length, Lengths of Head, Beak and Face, Length and Width of Shank, Metatarsal Perimeter, Dorso-sternal Height, Bicostal Length, Withers Height, and Thoracic and Abdominal Perimeters. A Principal Component Analysis was applied to the study of variable between both groups to explore the relationship between traits. Results: body length and height, and abdominal and thoracic perimeters were the most discriminative traits between groups. 'Non-lobe' group presented significative higher values only for body length.
