Abstract
Body volume is a three-dimensional measure recently applied in the study of the morphology of domestic livestock. The present study aimed to determine and characterize the body volume of Pelibuey sheep in the state of Colima. Body volume of ewes was determined using the equation to calculate the volume of a cylinder whose base is represented by the chest girth and whose height is illustrated by the body length. Data was analyzed using descriptive statistics, principal component analysis, and hierarchical cluster analysis. The body volume of ewes was 32.27 dm3 ± 6.14 dm3 with minimum and maximum values ranging from 19.58 dm3 to 51.86 dm3. Taking the municipality where the flock was located as a classification criterion, three conglomerates of ewes differentiated by live weight, body volume, chest girth, and body length were identified.
