No significant differences, between the Awassi and Coopworth lambs were recorded in: birth weight, liveweight gain (birth to weaning), and liveweight gain (weaning to 6 months). A trend for the Coopworths to have greater liveweight gains was noted. Significantly less wool was clipped from Awassi lambs (0.83 ± 0.06kg) than Coopworth lambs (1.46 ± 0.06kg). In comparison with the Coopworth, Awassi wool was coarser (31 v 35 µ), higher yielding (74% vs 82%), more yellow (Y-Z: 1.8 vs 4.2), of similar bulk, longer in the staple (72 vs 106mm) and more tender (57 vs 39 N/ktex). The teaser ram marked 94% of the Coopworth ewe lambs, but no Awassi's. The faecal egg counts of the Awassi lambs were lower (p<0.05) than the Coopworth's.
