Grazing Behaviour and Diet Selection by Dorper Sheep

Small Ruminant Research, 2000
The 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.

Laryngeal chondritis in two Dorper sheep

Veterinary Record Case Reports, 2020
SUMMARY Laryngeal chondritis is an acute obstructive upper respiratory condition characterised by severe dyspnoea and laryngeal stridor, considered an uncommon disease in sheep. In this study, we describe detailed clinical evolution, imaging and pathological findings of the first cases of laryngeal chondritis in Dorper sheep.

Feed efficiency improves sperm quality and viability of fertilisation in Dorper sheep

New Zealand Journal of Agricultural Research, 2023
The aim was to evaluate the influence of residual feed intake (RFI) on the semen characteristics of Dorper sheep after cryopreservation. Six Dorper sheep were used, classified from a population of 64 according to feed efficiency (groups of animals ...

Changes in the physiological, hematological and parasitological parameters of Dorper sheep in relation to residual feed intake and confinement environment.

Journal of Thermal Biology, 2023
The selection of animals with greater feed efficiency has unknown parasitological and physiological parameters when confined in full sun or shade. Thus, we aimed to assess the effect of residual feed intake (RFI) and the confinement environment on the ...

Vascularization of the muscles of the shoulder joint of a Dorper sheep

Hippology and Veterinary Sciences, 2023
The angioarchitecture of the intraorgan arterial bed of the studied muscles of the thoracic limb of the Dorper sheep is characterized by a modular type of structure. The direction of the arteries of the first and second orders inside the muscles usually does not correspond to the course of the muscle bundles, and their intrasystemic anastomoses form a ...

Interaction between residual feed intake and thermal environment on performance, nitrogen balance, ingestive behavior and carcass yield of dorper lambs.

Journal of Thermal Biology
Residual feed intake (RFI) is a nutritional variable used in genetic improvement programs, the relationship between the environment and the availability of energy and protein in the diet has not yet been explored.

Estimates of the genetic parameters of a Dorper flock in Brazil

Small Ruminant Research, 2019
Abstract 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 ...

Identification of the SP22 Sperm Protein in Santa Inês and Dorper Rams

Reproduction in Domestic Animals, 2010
The sperm membrane protein referred to as SP22 has been identified in different species and, at least in rats, is highly correlated with fertility. The goals of this study were to identify and to quantify the SP22 protein on spermatozoa from adult rams (Dorper and Santa Inês breeds), and to correlate its levels to morphological and kinematics ...
