Review on Population Status and Conservation Activity of Indigenous Cattle Breeds of Ethiopia

doi:10.7176/jbah/11-16-01

Abstract

Ethiopia has the home to at least 27 cattle breeds and an estimated 59.5 million head of cattle due to its diversified agroecology and topography and directly serves as for millions of people. Indigenous cattle breed has many important traits compared with exotic cattle breeds. Bos indicus breeds can effectively regulate their body temperature against thermal stress and are better adapted to hot weather than Bos taurus breeds. In addition, several breeds of Zebu and Zenga are able to withstand very harsh environmental conditions, and those characteristics have arisen through evolutionary adaptation. For examples, Begait cattle (Large East African Zebu) found in North-Western Ethiopia are well adapted to very dry climates and they can survive if they are able to drink only once every two days. However, despite the potential of the indigenous livestock currently, the genetic resources are becoming seriously endangered due to high genetic erosion resulting from biotic and abiotic factors. The objective of this review was to highlight threats, conservation methods and improvement activities currently done for indigenous cattle genetic resources in Ethiopia. Based on the review, among the world 1458 breeds all domestic mammalian and avian species, 17% are classified as being at risk and 58% are classified as unknown risk status. The major threats of livestock genetic resources are genetic dilution through the use of exotic germ plasma, feed shortage, illegal trafficking, inbreeding and interbreeding, and trypanosomiasis disease. This situation demands immediate action to save deteriorating genetic resources in the country. Some of endangered indigenous cattle breeds were conserved in ex-situ method at different state ranches, the Borana cattle breed as Did Tuyura Ranch, Horro cattle breed at Horro Ranch, Fogera cattle breed at Metekel Ranch and Andassa Agricultural Research Centre, and Menz sheep breed at Amed Guya Research Centre but, the results were not enough. Therefore, phenotypic and genotypic categorization of breeds will be further characterized, monitor the current population statistics, conservation of breeds under natural niche, and improvement programs will be implemented for all breeds and also improve the productivity of grazing land.

Highlights

Ethiopia can be considered as a center of livestock diversity and high population because of different indigenous cattle breeds are spread out diverse ecology, communities and production systems Solomon, G (2008)
Some of the ranches was Borana cattle bred as Did Tuyura and Abernossa Ranch, Horro cattle breed at Horro Ranch, Fogera cattle breed at Metekel ranch and Andassa Agricultural Research Centre and Menz sheep breed at Amed Guya Research Centre, Wolaita cattle ranch and Jigjiga ogaden cattle ranch are the only conservation attempts made in Ethiopia (IBC, 2004)
Borana cattle breed at Did Tuyura Ranch, Horro cattle breed at Horro Ranch, Fogera cattle breed at Metekel Ranch and Andassa Agricultural Research Centre, and Menz sheep at Amed Guya Research Centre are the only conservation attempts made in Ethiopia and other cattle breeds conventionally conserved by farmers

Summary

Introduction

Ethiopia can be considered as a center of livestock diversity and high population because of different indigenous cattle breeds are spread out diverse ecology, communities and production systems Solomon, G (2008). Sheko cattle breeds are found around the White Nile in the Sudan and adjacent lowlands of south west of Ethiopia where they are mainly kept by the Nuer people in the Akobo area of the Gambella region (DAGRIS, 2006) They are similar to the adjacent Aliab Dinka in the Sudan, and both have retained the large body size, long horns and small humps of the true Sanga. Based on the survey report of Nigatu A. et al, 2002) it was revealed that the Ethiopian Boran cattle known by the community 50 years ago were not identical with the current Ethiopian Boran types, especially in terms of their body size and coat color These phenotypic characteristics are a result of adaptation mechanisms of the breed to the harsh environments. There are two major approaches of conservation for livestock genetic resources are available
