Morphometric Characterization of Indigenous Goats in East Gojjam Zone, Amhara Region, Ethiopia

Abstract

This study was conducted in HuletEjuEnesie, GonchaSisoEnesie and EnbseSarMidir districts of East Gojjam Zone with the aim to Morphometric characterize indigenous goat populations.A total of 600 goats were sampled randomly for phenotypic characterization. The most dominant coat color pattern in the sampled populations wasplain and patchy with the most frequently observed coat color type being light red, white with red and white. Sex of animal had significant effect on all of the body measurements, except ear length, chest depth, and rump length and width. EnbseSarMidir district had significantly higher body measurement values than other districts. Dentition had significant differences on body weight and most of the linear body measurements. Correlations among body weight and linear body measurements were positive for both sexes. The result of the multiple regression analysis showed that heart girth explained more variation than any other linear body measurements in both does (71%) and bucks (82%). The prediction of body weight could be based on regression equation BW = -37.93 + 0.92CG for female sample population and BW= -44.47 + 1.02CG for male sample goat population. To sustainably utilize these goat population the production constrains should be solved and selective community-based breeding strategies should be designed and implemented.
