The history and performance of Dorper sheep in Western Australia

, 2001
The history of Dorper sheep in Western Australia is reviewed, since their arrival as embryos from South Africa, in 1996. Limited data are provided - mainly small-scale observations and anecdotes - on reproduction, growth rates, carcass characteristics ...

Methodological Determinants of Grayscale Pixel Intensity in Ram Testicular Ultrasonography: Effects of ROI Placement and Imaging Plane Across Age Groups and Two Reproductive Periods

Reproduction in Domestic Animals, Volume 61, Issue 8, August 2026.
ABSTRACT Testicular ultrasonography is increasingly used in ram breeding soundness evaluations, yet methodological standardization of quantitative grayscale image analysis remains limited. The primary objective of this study was to determine the effects of region‐of‐interest (ROI) placement and imaging plane on testicular parenchymal numerical pixel ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, Volume 199, Issue 1, Page e21-e29, 4/11 July 2026.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

From Assessment to Optimization: A Comprehensive Review of the Mutton Quality Evaluation Index, Factors, and Improvement Strategies

Food Frontiers, Volume 7, Issue 3, May 2026.
This graphical abstract summarizes the comprehensive framework of mutton quality, including evaluation indices, influencing factors, and improvement strategies. Meat quality is systematically assessed through multiple dimensions, including flavor, color, pH, tenderness, water‐holding capacity, intramuscular fat, and nutritional composition.

Ventricular dyssynchrony as a cause of structural disease in the heart of Dorper sheep

Onderstepoort J Vet Res, 2004
Ventricular dyssynchrony is a disturbance of the normal, organized electromechanical coupling of the two ventricles. This condition has many causes, such as left bundle branch block, ventricular preexcitation, right ventricular pacing and right ventricular premature ventricular complexes (PVCs).

Effect of Diet Neutral Detergent Fibre Content on Dry Matter Intake, Nutrient Digestibility, Growth Efficiency and Carcass Characteristics of Finishing South African Mutton Merino Wether Lambs

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Feeding South African Mutton Merino lambs low‐NDF lucerne hay diets improved nutrient digestibility, energy utilisation, growth efficiency, and carcass quality. Despite lower intake at the lowest NDF level, fibre digestibility and feed conversion improved, indicating that highly digestible, low‐NDF finishing diets enhance lamb growth and carcass traits.

Moringa stenopetala Leaves and Cafeteria Leftover as Nonconventional Supplements in the Diets of Local Gamo Sheep: Nutrient Utilization, Growth Performance and Economic Efficiency

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
For smallholders having plenty of cafeteria leftovers and M. stenopetala leaves, blended feeding of the ingredients is more profitable than their exclusive feeding. Provided that they are comparably available, sole supplementation of M. stenopetala is more advantageous and profitable than sole supplementation of cafeteria leftovers.

DataSheet1_Genetic Basis of Dorper Sheep (Ovis aries) Revealed by Long-Read De Novo Genome Assembly.ZIP

, 2022
Dorper sheep (Ovis aries) (DPS), developed in the 1930s by crossing Dorset Horn and Blackhead Persian sheep in South Africa, is a world-famous composite breed for mutton production. The genetic basis underlying this breed is yet to be elucidated.

Genetic structure of South African Nguni (Zulu) sheep populations reveals admixture with exotic breeds.

PLoS ONE, 2018
The population of Zulu sheep is reported to have declined by 7.4% between 2007 and 2011 due to crossbreeding. There is insufficient information on the genetic diversity of the Zulu sheep populations in the different area of KwaZulu Natal where they are ...

The performance of the Dorper and Dorper X Red Maasai sheep

, 2013
Data on 1199 lambs collected over a 10 year period (1978 to 1987) on Dorper and Dorper X Red Maasai sheep at Ol'Magogo were used in this study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages of ...
