The aim of the present work was to analyse the morpho-productive parameters of the R1 sheep resulting from the crossing of the local sheep from the north-eastern area of the country with the Awassi breed. The results showed that compared to the milk production of Tsurcana breed during the milking period (120 days), the milked milk production of R1 sheep in the first lactation is higher by 17.30 kg, the differences being very significant (P<0.001). Following the analysis of the external morphological characteristics of the R1 sheep, it emerged that the only character specific to the Awassi breed that was transmitted in a higher percentage is the long and drooping ears (36.7%), the other characters being transmitted in a reduced percentage (3.3-16.7%). The reproductive indices showed the highest values in the case of R1 sheep (compared to the Tsurcana breed, the prolificacy is 28.6% higher, and the numerical productivity index is 41.4% higher). All these results recommend the improvement of local sheep from the north-eastern area of our country through crossbreeding with the Awassi breed up to the second generation of absorption.
