Conformation trait characterization of indigenous goats in selected districts of East Gojjam zone, Amhara region, Ethiopia

Abstract

ABSTRACT Morphological differences between and within the indigenous goat populations have important economic and socio-cultural values to the communities. This study was phenotypically characterized conformation traits of indigenous goats in selected districts of East Gojjam Zone, Amhara Region, Ethiopia. A total of 706 (589 does, and 117 bucks) mature (>1PPI), healthy, lactating does, and intact bucks goats were used to collect qualitative and quantitative data. The qualitative and quantitative data were analyzed for female and male goats separately using the frequency and general linear model (GLM) procedures of SAS, 9.0, respectively. Most of the does had intermediate fore udder attachment, teat placement side and rearview, and strong central ligament. Most goats were explained by intermediate rear legs set side view, less sloped rump profile, intermediate angle, and strong loin strength. The district and goats dentition had significant influence on does’ bodyweight and most conformation trait measurments. Heart girth (r = 0.82) in does, and neck circumference (r = 0.68) in bucks showed the highest strong and positive correlation (P < 0.001) with bodyweight and were the utmost important variables to predict bodyweight. Indigenous goats in the study area have a dairy aptitude. However, further studies are needed to identify the indigenous goats for their production purpose.
