Abstract
Number of European sheep breeds were introduced to Egypt since the forties. The breeding plans involved assessing their performance under Egyptian conditions; and to upgrade the local breeds. Suffolk - crosses with Ossimi (Sc), performed better than both parents, heavier body weights and longer breeding season. Low Sc was suitable for the Egyptian conditions than high Sc.  Hampshire crosses with Ossimi did not perform well and were not recommended. Crosses of Fleisch Merino (Mc) with Ossimi or Barki were better than both parents. Individual heterosis contributes highly to the 1st cross, and maternal heterosis contributes to the backcrosses.  Merino crosses mate each 8 months, with better performance in May mating, in consistent with their oestrus activity.Crossing Rahmani (R)and Ossimi (O) with Finn landrace (F) sheep, improved prolificacy of the 1st crosses by 69 and 65 % in FR and FO, respectively, and by half these values for the 1/4 Finn crosses with ability to mate each 8 months, they performed well with the smallholders in the villages. Romanov breed (V) improved annual fecundity of 1/4 VR by 25%, having slight advantage over the Finn-cross. Chios crosses with Ossimi were better than their mid-parent and weaned heavier lambs.
