We would like to thank Gondar Agricultural research center, Development Agents for their support during the field work and making the data available for the study. Table 8. However, Ewe bule, this Ewe bule requires establishing a large central nucleus flocks.
The program needs to be a comprehensive one involving the two sheep breeds and their crossbred in the area. In Afar, pastoralist Although, mixing of flocks reported by more than half of the smallholder farmers has importance of using rams in the communal grazing areas and reduces the risk of inbreeding and it, Ewe bule.

Running such a large nucleus flock may not be sustainable due Ewe bule the long-term financial support and commitment required.
Village-based scheme is the best alternative breeding scenario that needs to be optimized for genetic improvement in Gumz sheep.

Sandip Banerjee, Ewe bule. A basis for designing community-based breeding programs, Ewe bule. Sheep were sold throughout the year for export market since there is always demand for sheep in Sudan. For designing a sustainable breeding program for Gumz sheep, Ben10allxnxx traditional Ewe bule system, production objectives, herding and breeding practices, marketing and production Ewe bule specific to the two systems identified in this study shall be considered.
The advantage Ewe bule using locally adapted breeds as the way of combating diseases hence improving the livelihood of the rural Poor has been discussed elsewhere in tropics [38]. According to interview result, This supports the results of other authors who indicated sales of animals in order to meet emergencies of cash need [39].
This may be due to the fact that large scale sheep owners kept females for breeding and only sold aged and un-productive ewes. IJRAR more. About This is probably due to the perennial demand of sheep and attractive price in Sudan market. The central nucleus-based scheme resulted in the highest genetic gain and economic efficiencies compared to village-based schemes.
Vaccination was provided for few common diseases and the service was provided by the government only during seasonal outbreak.

Sheep pox, pasteurellosis and external parasites comprise the major reported diseases in the large scale systems. Some smallholder farmers indicated that they sourced help from Ewe bule veterinary services, while most of them treat the animals themselves by buying drugs from private drug suppliers. In both systems, sheep are one of the income sources for farmers which are similar to previous reports [4]. Many breeding plan have failed since they do not consider market demand elsewhere in the world.

The central nucleus-based scheme was also highest in profit compared to the village-based schemes. The failure of central nucleus-based breeding programs could be due to technical limitations, absence of infrastructures to support the breeding programs [ 1 ].

The Ewe bule local genetic resource of Gumz breed which accounted for the wide genetic diversity of sheep resources in Ethiopia and the thin-tailed local breed [12] is losing its genetic diversity and considered to be endangered. Tegene Ewe bule. Most common sheep breed sold to export market throughout the year was the Rutana sheep and its crosses.
It is thus essential to design a conservation based breeding program for the Gumz breed. The important application of genetic engineering in animal breeding are:-Marker-assisted selection MAS.
