A crossbreeding experiment was carried out by Ministry of Agriculture using imported German Mutton Merino (M) on both Ossimi (O) and Barki (B) subtropical, fat-tailed sheep. The plan was to grade the local sheep up to 3/4 M-l/4 local, and to interbred these cross in an attempt to produce medium wool types of sheep. Number of ewe records available for the analysis were 6959 out of 2168 ewes from the 3 purebreds, their first cross and backcroses to Merino.
