Comparative Performance Evaluation of Gumz, Rutana and their Crosses and Designing Conservation-based Breeding Program for Gumz Sheep in North Western Lowlands of Amhara, Ethiopia

Abstract: Gumz sheep are among the indigenous sheep that contribute to the genetic diversity of Ethiopian sheep genetic resource and it is the only thin-tailed sheep in Ethiopia. However, indiscriminate crossbreeding or extensive use of exotic germplasms is seriously threatening the existence of indigenous populations. The lack of detailed information and understanding about indigenous breeds, including their threat status, is perceived to be the most important hindrance to their conservatio...

DESIGNING SUSTAINABLE BREEDING PROGRAM FOR BEGAIT GOAT IN WESTERN TIGRAY, NORTHERN ETHIOPIA

Abstract: Indigenous breeds adapt and survive in often challenging environments and diverse agroecological areas representing an important genetic resource for livelihood of their owners and the national economy at large. Therefore, there is a need to improve the productivity of indigenous animals through developing sustainable breeding programs so as to enhance their competitive advantage in the face of crossbreeding threats. The current study was performed in Kafta Humera district of Tigra...
