open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2016
Ultrasonic measurements of Musculus longissmus dorsi thoracis et lumborum (MLD) were taken of Dorper (n=99) and Dorper x Merino (n=65) lambs at 156 days of age and comparisons made to various body dimensions to ascertain whether sex, genotype, birth type and live weight had any effect on these parameters.

A Comparative Assessment of Dorper Sheep in Different Production Environments and Systems

open access: yesSmall 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.

Although Dorper sheep may be infested with the scab mite, Psoroptes ovis, this does not seem to cause production losses.
