Phenotypic characterization of indigenous goat population in North Wollo Zone, Amhara Region, Ethiopia

Abstract

This study characterized indigenous goats in the North Wollo Zone, Amhara region, Ethiopia, focusing on their morphometric traits. A total of 550 goats (467 does and 83 bucks) were randomly selected for data collection, excluding pregnant and sick animals. Eight qualitative 19 (bucks) and 24 (does) linear body measurements were measured. Statistical analysis revealed that the agro-ecological zone, sex, and age significantly influenced both qualitative and quantitative traits. Highland goats, male goats, and older goats were generally larger. There was a positive and significant correlation between body weight and linear body measurements for both males and females. Among the body measurements, chest girth was identified as the best predictor of body weight, explaining more variation than other traits. These findings provide valuable insights into the morphometric characteristics of indigenous goats and can serve as a baseline for future research on goat breeding and management in the region. The study highlights the importance of understanding local goat populations to improve livestock management practices in smallholder systems.
