A comparative assessment of Dorper sheep in different production environments and systems

Small Ruminant Research, 2000
Performance of Dorper sheep was compared to other breeds in pure and cross-breeding evaluations under different production systems. The number of ewes lambed per ewe joint (E(L)/E(J)) varied for the Dorper from 0.68 to 0.91 (average 0.81) and for other breeds and crosses from 0.65 to 0.91 (average 0.82). Average litter size (L(B)/lambing) varied from 1.
