Background:
Guaymi and Guabala Creole cattle are unique genetic resources adapted to tropical systems in Panama.
Aim:
This study aimed to compare the morphometry and morphology using classical zoometric analysis and automated classification via the Mooebius web app and random forest models.
Methods:
Morphological and morphometric data from 225 adult cattle were analyzed using nested analysis of variance and chi-square tests. A supervised Random Forest (RF) classifier and web-based index calculator (Mooebius) were developed for aptitude prediction.
Results:
There were significant differences (p < 0.05) in body proportions and pelvic conformation. The Guaymi cattle showed lighter morphologies with dairy aptitude, whereas the Guabala were more robust and meat-oriented. The RF models achieved accuracies ranging from 86.4% (raw measurements) to 90.9% (index-based models), identifying body length and thoracic perimeter as the most influential predictors.
Conclusion:
The integration of morphological and morphometric data with artificial intelligence techniques provides an effective decision support tool for the conservation and selection of native breeds in tropical conditions.
