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.

Productive performance of Dorper sheep
Small Ruminant Research, 2000 The Dorper is a hardy South African composite breed, derived from a cross between the Black-headed Persian and the Dorset Horn. Dorpers are regarded as early-maturing, and ewes lambed at an age of 1 year in one study. Age at first lambing was higher in other literature sources cited.

Status of Dorper sheep as hosts of ectoparasites
Small Ruminant Research, 2000Seventeen ixodid tick species or subspecies have been collected from Dorper sheep in South Africa. The diseases transmitted or the conditions caused by these ticks in sheep are discussed. Although Dorper sheep may be infested with the scab mite, Psoroptes ovis, this does not seem to cause production losses.

The history of the Dorper sheep
Small Ruminant Research, 2000This short history of the Dorper sheep traces its background and the steps taken to develop that breed in South Africa. The most important traits considered for the developing of the Dorper are listed and the breeding system outlined. The development of the White Dorper is also detailed and the breed improvement programs are indicated.

Grazing behaviour and diet selection by Dorper sheep
Small Ruminant Research, 2000The grazing behaviour and diet selection by Dorper sheep, as well as other related aspects (pasture intake, walking habits and trampling) is reviewed. It was clear that Dorper sheep are less-selective grazers, compared to Merino-type breeds. Dorpers utilised shrubs and bushes to a greater extent, but grass to a lesser extent in relation to Merino sheep.

Estimates of the genetic parameters of a Dorper flock in Brazil
Small Ruminant Research, 2019Abstract Dorper sheep breeding increased in several countries but the estimates of genetic parameters for some traits remain unknown. Therefore, this study aimed to estimate genetic parameters for body weights at birth (BW), 30 (W30), 60 (W60) and 90 (W90) days of age, total and daily weight gains from 0 to 30 (WG1 and DWG1), 30 to 60 (WG2 and DWG2 ...
