Abstract

This exploratory survey of indigenou cattle populations was conducted in Awi, East and West Gojjam Zones of Amhara region, Ethiopia, to identify and phenotpically describe the indigenous cattle populations. Four focus group discussions with key informants were held and quantitative and qualitative phenotypic data were generated from 730 animals (299 males and 501 females). Outcomes of focus group discussions revealed that one cattle type has been threatened by increasing preference of farmers for smaller body sized animals. Results from analysis of variance (ANOVA) on quantitative variables showed significant differences between sites. The Chi-square test indicated that the level of association of site with most categorical variables was medium except for a few cases where it was found higher. The Mahalanobis distances between sites were highly significant (P<0.0001). The maximum and minimum distances were observed respectively between Ankasha and Enemay both for female and male sample populations. Discriminant analysis was run to classify sample cattle populations from all sites into their respective sites with an overall matching rate of 80.9 % and 79.9% for females and males, respectively. The information obtained from focus group discussions and results of univariate and multivariate analysis on phenotypic variations led to identification of two cattle populations that deemed to be distinct breed types (Gojjam Highland Zebu and the Fogera).While the indigenous cattle population of the study area was not homogenous, the identified breeds are significantly different morphologically and subsequent molecular investigations need to be made to confirm their genetic distinctiveness and measure the level of genetic introgression especially on the Fogera.

Key words: Phenotypic characterization, Indigenous cattle populations, Awi, East and West Gojjam Zones.
