Summary

The zebu population of Somalia includes four main types (Boran, Dawara,, Gasara and Surqo), which cannot be considered as breeds in the same sense as cattle in Europe. Boran, Dawara and Gasara are included in the type known as East African Shorthorned zebu, while the Surqo is regarded as an ancient stable mixture of zebu and Sanga (see Figure 1).

The task of identifying the genetic relationships existing among these types, within a rather heterogeneous population, could best be approached through the study of marker loci like thoseicontrolling the immmogenetic and biochemical polymorphic systems, rather than through the comparison of morphological traits.

Research was continued along these lines to facilitate the genetic characterization of Boran and Dawara types (Di Stasio et al., 1978.and 1980), and the study was extended to include the Surqo type ird-a comparison of the results.
